The build apparatus 1 is an apparatus that is configured to build a three-dimensional structural object (namely, a three-dimensional object that has a magnitude (a size) in each of three-dimensional directions). Especially, in the present example embodiment, the build apparatus 1 builds the three-dimensional structural object by performing an additive processing. Namely, the build apparatus 1 additively builds the three-dimensional structural object.
The data generation server 2 is an apparatus that is configured to generate three-dimensional model data representing a three-dimensional model of the three-dimensional structural object to be additively built by the build apparatus 1. The data generation server 2 may be referred to as a data generating apparatus. The data generation server 2 transmits the generated three-dimensional model data to the build apparatus 1 through the communication network 4. The build apparatus 1 builds the three-dimensional structural object based on the three-dimensional model data transmitted from the data generation server 2.
The terminal apparatus 3 is an apparatus that is operable by a user to set (namely, designate) feature information related to a feature of the three-dimensional structural object to be additively built by the build apparatus 1. In the below-describe description, the user who is allowed to operate the terminal apparatus 3 is referred to as the “terminal user”. The terminal user may be typically a person who wants to build the three-dimensional structural object by using the build apparatus 1.

In the below-described description, a positional relationship of various components included in the build apparatus 1 will be described by using a build coordinate system corresponding to an XYZ rectangular coordinate system that is defined by a X-axis, a Y-axis and a Z-axis that are perpendicular to one another. Note that each of an X-axis direction and a Y-axis direction is assumed to be a horizontal direction (namely, a predetermined direction in a horizontal plane) and a Z-axis direction is assumed to be a vertical direction (namely, a direction that is perpendicular to the horizontal plane, and substantially a vertical direction or a gravity direction) in the below-described description, for convenience of the description. Moreover, rotational directions (in other words, inclination directions) around the X-axis, the Y-axis and the Z-axis are referred to as a θX direction, a θY direction and a θZ direction, respectively. Here, the Z-axis direction may be the gravity direction. Moreover, an XY plane may be a horizontal direction.
The build apparatus 1 is configured to perform a build operation for forming the three-dimensional structural object.

When the workpiece W is a below-described stage 131, the build apparatus 1 is configured to form the three-dimensional structural object on the stage 131. When the workpiece W is an existing object placed on the stage 131 (alternatively, placed on the stage 131), the build apparatus 1 may be configured to form the three-dimensional structural object on the existing object. In this case, the build apparatus 1 may form the three-dimensional structural object that is integrated with the existing object. An operation for forming the three-dimensional structural object that is integrated with the existing object may be regarded to be equivalent to an operation for adding a new structural object to the existing object. Note that the existing structural object may be an item that needs to be repaired having a missing part, for example. The build apparatus 1 may form the three-dimensional structural object on the item that needs to be repaired to fill in the missing part of the item that needs to be repaired. Alternatively, the build apparatus 1 may form the three-dimensional structural object that is separable from the existing object. Note that
In the present example embodiment, an example in which the build apparatus 1 build the three-dimensional structural object by performing the additive processing (the additive building) based on a Laser Metal Deposition (LMD). In this case, it can be said that the build apparatus 1 is a 3D printer that forms an object by using an Additive layer manufacturing technique. Note that the Additive layer manufacturing technique may be referred to as a Rapid Prototyping, a Rapid Manufacturing or an Additive Manufacturing. The Laser Metal Deposition may be referred to as a Direct Metal Deposition, a Direct Energy Deposition, a Laser Cladding, a Laser Engineered Net Shaping, a Direct Light Fabrication, a Laser Consolidation, a Shape Deposition Manufacturing, a Wire Feed Laser Deposition, a Gas Through Wire, a Laser Powder Fusion, a Laser Metal Forming, a Selective Laser Powder Re-melting, a Laser Direct Casting, a Laser Powder Deposition, a Laser Additive Manufacturing or a Laser Rapid Forming.
The build apparatus 1 forms the three-dimensional structural object by processing a build material M with a processing light EL. The build material M is a material that is molten by an irradiation with the processing light EL having a predetermined intensity or more intensity. At least one of a metal material and a resin material is usable as the build material M, for example. However, another material that is different from the metal material and the resin material may be used as the build material M. The build materials M are powder-like or grain-like materials. Namely, the build materials M are powdery materials. However, the build materials M may not be the powdery materials. For example, a wired-like build material or a gas-like build material may be used as the build material M, for example.

The material supply source 11 supplies, to the processing apparatus 12, the build materials M the amount of which is necessary for forming the three-dimensional structural object per unit time by supplying the build materials M the amount of which is based on the necessary amount.
The processing apparatus 12 forms the three-dimensional structural object by processing the build materials M supplied from the material supply source 11. In order to form the three-dimensional structural object, the processing apparatus 12 include a processing head 121 and a head driving system 122. Furthermore, the processing head 121 includes an irradiation optical system 1211 that is configured to emit the processing light EL and a material nozzle 1212 that is configured to supply the build materials M.

The head driving system 122 moves the processing head 121 along at least one of the X-axis, the Y-axis, the Z-axis, the 8X direction, the GY direction and the 8Z direction, for example. When the head driving system 122 moves the processing head 121, a relative position between the processing head 121 and the stage 131 (furthermore, the workpiece W placed on the stage 131) changes.
The build materials M supplied from the material nozzle 1212 are irradiated with the processing light EL emitted from the irradiation optical system 1211. As a result, the build materials M are molten. Namely, a melt pool including the molten build materials M is formed. When the melt pool is not irradiated with the processing light EL due to the movement of the processing head 121, the build materials M molten in the melt pool are solidified. Namely, a build object corresponding to a deposition of the solidified build materials M is formed. The build apparatus 1 repeats a series of the build process including the formation of the melt pool by the irradiation with the processing light EL and the solidification of the molten build materials M while relatively moving the processing head 121 along at least one of the X-axis direction and the Y-axis direction. As a result, a structural layer that is an aggregation of the build object formed in a pattern based on a moving trajectory of the melt pool is formed. The build apparatus 1 forms a plurality of structural layers in order so that the plurality of structural layers are laminated. As a result, the three-dimensional structural object that is an aggregation of the plurality of structural layers is formed.

The stage driving system 132 moves the stage 131 along at least one of the X-axis, the Y-axis, the Z-axis, the θX direction, the 9Y direction and the 9Z direction. When the stage driving system 132 moves the stage 131, a relative position between the processing head 121 and the stage 131 (furthermore, the workpiece W placed on the stage 131) changes.

In this case, the parameter setting GUI 911 may include a label indicating a name of a setting item of the numerical parameter, and a text box in which a setting value of the numerical parameter can be inputted (alternatively, a combo box, a drop-down list, or a radio button in which the setting value of the numerical parameter can be designated among a plurality of candidate values). Alternatively, the parameter may include a flag parameter for setting the shape of the three-dimensional structural object. The flag parameter is used to set the shape of the three-dimensional structural object to be one shape corresponding to the value of the flag parameter. For example, when the flag value of the flag parameter is set to a flag value of 1, the shape of the three-dimensional structural object may be set to be a first shape corresponding to the flag value of 1, and when the flag value of the flag parameter is set to a flag value of 2, the shape of the three-dimensional structural object may be set to be a second shape corresponding to the flag value of 2. In this case, the parameter setting GUI 911 may include a label indicating a name of a setting item of the flag parameter, and a text box in which a setting value (the flag value) of the flag parameter can be inputted (alternatively, a combo box, a drop-down list, or a radio button in which the setting value of the flag parameter can be designated among a plurality of candidate values).
For example, when a position of at least a part of the three-dimensional structural object changes, the shape of the three-dimensional structural object changes. Thus, the parameter may include a parameter that defines the position of at least a part of the three-dimensional structural object. For example, when a size of at least a part of the three-dimensional structural object changes, the shape of the three-dimensional structural object changes. Thus, the parameter may include a parameter that defines the size of at least a part of the three-dimensional structural object. For example, when a shape of at least a part of the three-dimensional structural object changes, the shape of the three-dimensional structural object changes. Thus, the parameter may include a parameter that defines the shape of at least a part of the three-dimensional structural object. For example, when a direction of at least a part of the three-dimensional structural object (for example, a direction in which at least a part of the three-dimensional structural object faces or extends) changes, the shape of the three-dimensional structural object changes. Thus, the parameters may include a parameter that defines the direction of at least a part of the three-dimensional structural object.
The setting value of the parameter set by the terminal user (namely, the value of the parameter that has been set) may be displayed in the parameter setting GUI 911. Namely, the input screen 91 including the parameter setting GUI 911 may display the value of the parameter that has been set. The value of the parameter that has been set may be provided to the input screen 91. The setting value of the parameter displayed in the parameter setting GUI 911 may be updated each time the terminal user sets the parameter again. The setting value of the parameter displayed in the parameter setting GUI 911 may be updated periodically or at random cycles. The setting value of the parameter displayed on the parameter setting GUI 911 may be updated based on the terminal user's instruction (for example, triggered by the terminal user pressing a button that is included in the setting GUI 9 and that is for updating the setting value of the parameter). As a result, the terminal user can recognize the latest setting value of the parameter set by the terminal user himself. Note that the updating of the setting value of the parameter displayed in the parameter setting GUI 911 may be performed under the control of the display control unit 211 of the data generation server 2. In this case, the display control unit 211 may generate the GUI information so that the setting value of the parameter displayed in the parameter setting GUI 911 based on the shape information obtained from the terminal apparatus 3. Alternatively, the updating of the setting value of the parameter displayed in the parameter setting GUI 911 may be performed under the control of the display control unit 311 of the terminal apparatus 3. In this case, the display control unit 311 may update the setting value of the parameter displayed in the parameter setting GUI 911 based on the shape information obtained by the information obtaining unit 312 of the terminal apparatus 3.
In order to set the shape information, the terminal user may select an icon that defines the shape of the three-dimensional structural object by using the input screen 91 in addition to or instead of setting the value of the parameter. The icon is associated with a specific shape that is allowed to be set as the shape of the three-dimensional structural object. In this case, the input screen 91 may include an icon selection GUI 912 including a plurality of icons (alternatively, at least one icon) that are selectable by the terminal user to set the shape of the three-dimensional structural object to be the specific shape. Each of the plurality of icons included in the icon selection GUI 912 is selectable by the terminal user. The terminal user may set the shape information by selecting, from among the plurality of icons included in the icon selection GUI 912, one icon associated with the shape of the three-dimensional structural object which the terminal user wants to build. The information obtaining unit 312 may obtain, as at least a part of the shape information, icon information related to the icon selected by using the icon selection GUI 912 (namely, information related to the shape associated with the selected icon).
In the icon setting GUI 912, the icon selected by the terminal user may be displayed in a display aspect that is different from that of the icon not selected by the terminal user.
Note that the terminal user may set the shape information by drawing the shape of the three-dimensional structural object on the setting GUI 9 (for example, on the input screen 91) in addition to or instead of selecting one icon from the plurality of icons. In this case, the setting GUI 9 may include a drawing GUI that allows the terminal user to draw the shape of the three-dimensional structural object.
The input screen 91 may include a feature setting GUI 913 that is operable by the terminal user to set the feature information related to any feature of the three-dimensional structural object that is different from the shape of the three-dimensional structural object. For example, as illustrated in
A setting value of the feature information set by the terminal user may be displayed in the feature setting GUI 913. The setting value of the feature information displayed in the feature setting GUI 913 may be updated each time the terminal user sets the feature information again. The setting value of the feature information displayed in the feature setting GUI 913 may be updated periodically or at random cycles. The setting value of the feature information displayed in the feature setting GUI 913 may be updated based on the terminal user's instructions (for example, triggered by the terminal user pressing a button included in the setting GUI 9 to update the setting value of the feature information). As a result, the terminal user can recognize the latest setting value of the feature information set by the terminal user himself. A method of displaying the setting value of feature information may be the same as a method of displaying the setting value of the parameter described above, so a detailed description of this method is omitted.
Note that the shape information set by using the parameter setting GUI 911 may be set by using the icon selection GUI 912. Similarly, the shape information set by using the icon selection GUI 912 may be set by using the parameter setting GUI 911. In short, the method of setting the shape information is not limited as long as the shape information is set by using the input screen 91. The same is true for the feature information.
The output screen 92 is a screen (in other words, an output unit) that is capable of displaying a three-dimensional model (namely, model information) based on the shape information set by the terminal user using the input screen 91. For example, the output screen 92 may be capable of displaying a three-dimensional model based on the value of the parameter set by the terminal user using the parameter setting GUI 911 included in the input screen 91 (namely, a three-dimensional model of the three-dimensional structural object having the shape defined by the value of the parameter set by the terminal user). For example, the output screen 92 may be capable of displaying a three-dimensional model based on the icon selected by the terminal user using the icon selection GUI 912 included in the input screen 91 (namely, a three-dimensional model of the three-dimensional structural object having the specific shape associated with the icon selected by the terminal user). For example, the output screen 92 may be capable of displaying a three-dimensional model based on the feature information set by the terminal user using the feature setting GUI 913 included in the input screen 91 (namely, a three-dimensional model of the three-dimensional structural object having the feature defined by the feature information set by the terminal user).
The data generation server 2 provides the three-dimensional model based on the shape information set by the terminal user using the input screen 91 to the output screen 92 displayed by the display apparatus 35 of the terminal apparatus 3. Specifically, in order to generate the GUI information related to the setting GUI 9 including the output screen 92, the data generation unit 213 of the data generation server 2 generates, based on the shape information (furthermore, other feature information if necessary) obtained by the information obtaining unit 212 from the terminal apparatus 3, three-dimensional model data representing the three-dimensional model based on the shape information set by the terminal user. Then, the display control unit 211 generates the GUI information related to the setting GUI 9 including the output screen 92 on which the three-dimensional model represented by the three-dimensional model data generated by the data generation unit 213 is displayed. The, the GUI information generated by the display control unit 211 is transmitted to the terminal apparatus 3 by using the communication apparatus 23. The display apparatus 35 of the terminal apparatus 3 displays the setting GUI 9 based on the GUI information transmitted from the data generation server 2. Namely, the display apparatus 35 uses the output screen 92 to display the three-dimensional model based on the shape information set by the terminal user. Namely, the display apparatus 35 displays, on the output screen 92, the three-dimensional model based on the shape information set by the terminal user. As a result, the terminal user can recognize the shape and so on of the three-dimensional model based on the shape information set by the terminal user relatively easily.
The three-dimensional model displayed on the output screen 92 may be a three-dimensional model in any format. For example, a three-dimensional model corresponding to a solid model or a surface model (see
The display control unit 211 may generate the GUI information related to the setting GUI 9, including the output screen 92 on which the three-dimensional model based on the newly obtained shape information is displayed, each time the information obtaining unit 212 newly obtains the shape information from the terminal apparatus 3. The display control unit 211 may generate the GUI information related to the setting GUI 9, including the output screen 92 on which the three-dimensional model based on the shape information newly set by the terminal user is displayed, each time the shape information is newly set (for example, changed or updated) by the terminal user using the setting GUI 9. The display control unit 211 may update the three-dimensional model displayed on the output screen 92 each time the shape information is newly set (for example, changed or updated) by the terminal user using the setting GUI 9. In this case, the three-dimensional model that reflects the shape information set by using the input screen 91 in real time is displayed on the output screen 92. As a result, the terminal user can relatively easily recognize the shape and so on of the three-dimensional model based on the latest shape information set by the terminal user himself. Alternatively, the display control unit 211 may generate the GUI information related to the setting GUI 9, including the output screen 92 on which the three-dimensional model reflecting the shape information set by using the input screen 91 is displayed, periodically or in a random cycle. In this case, the output screen 92 updates the three-dimensional model displayed on the output screen 92 periodically or at random cycles. Alternatively, the display control unit 211 may generate, based on the terminal user's instruction (for example, triggered by the terminal user pressing a button included in the setting GUI 9 to update the three-dimensional model displayed on the output screen 92), the GUI information related to the setting GUI 9, including the output screen 92 on which the three-dimensional model reflecting the shape information set by using the input screen 91. In this case, the output screen 92 updates the three-dimensional model displayed on the output screen 92 at a timing desired by the terminal user.
The display control unit 211 may generate the setting GUI 9 including the input screen 91 according to a type of the three-dimensional structural object so that the terminal user can set appropriate shape information according to the type of the three-dimensional structural object that is additively built by the build apparatus 1. Namely, the display control unit 211 may control the display apparatus 35 to display the setting GUI 9 including the input screen 91 according to the type of the three-dimensional structural object. In the present example embodiment, an example in which the build apparatus 1 builds the three-dimensional structural object that includes at least one of a pipe and a plate will be described, wherein the pipe corresponds to a member having a hollow structure (note that the pipe may be referred to as a tube), and the plate is a plate-like member, a size of the plate-like member in a direction perpendicular to a thickness direction is larger than a size of plate-like member in the thickness direction. Thus, in the below-described description, the input screen 91 that is displayed when the three-dimensional structural object includes the pipe and the input screen 91 that is displayed when the three-dimensional structural object includes the plate will be described in order. Namely, the input screen 91 for setting the shape information related to the shape of the pipe and the input screen 91 for setting the shape information related to the shape of the plate will be described in order.
As illustrated in
When the shape information is set by using the plurality of points P through which the pipe passes, the three-dimensional model with which the plurality of points P are associated may be displayed on the output screen 92, as illustrated in

As illustrated in
Incidentally, when each of the position, the direction, and the strength of the curvature of at least a part of the pipe changes, a trajectory along which the pipe extends changes. Thus, each of the parameter that defines the position of at least a part of the pipe, the parameter that defines the direction of at least a part of the pipe, and the parameter that defines the strength of the curvature of at least a part of the pipe may be referred to as a trajectory parameter that defines the trajectory along which the pipe extends.
As illustrated in
In the present example embodiment, the parameter setting GUI 911pi #4 may be a GUI for setting a value of a parameter that defines the size of a cross-section of at least a part of the pipe. For example, as illustrated in
The size of the cross-section of at least a part of the pipe may include a size of the cross-section along a first direction that is along the cross-section (in other words, a first direction that intersects with the centerline C of the pipe). For example, as illustrated in
The size of the cross-section of at least a part of the pipe may include a size of the cross-section along a second direction that is along the cross-section and that intersects with (typically, is perpendicular to) the first direction. For example, as illustrated in
Incidentally, when the shape of the cross-section of the pipe is a rectangular shape, the size of the cross-section of the pipe along the first direction may mean a distance (a length) between two outer surfaces of the pipe (outer walls of the pipe) facing each other along the first direction, and the size of the cross-section of the pipe along the second direction may mean a distance (a length) between two outer surfaces of the pipe (outer walls of the pipe) facing each other along the second direction. When the shape of the cross-section of the pipe is a circular shape, the size of the cross-section of the pipe along each of the first and second directions may mean a diameter of the outer surface of the pipe. In both cases, the size of the cross-section of the pipe along each of the first and second directions may be referred to as an outer diameter of the pipe.
The size of the cross-section of at least a part of the pipe may include a thickness of a wall (in other words, a pipe wall) of the pipe along the cross-section. For example, as illustrated in
When the size of the cross-section of at least a part of the pipe along the first direction, the size of the cross-section of at least a part of the pipe along the second direction, and the thickness of the wall of at least a part of the pipe are determined, each of an inner diameter of the pipe (namely, a diameter of the inner surface of the pipe or a distance (a length) between two inner side faces of the pipe facing each other) and the outer diameter of the pipe (namely, the diameter of the outer surface of the pipe) is determined. Therefore, setting the value of the parameter that defines the size of the cross-section of at least a part of the pipe along the first direction, the value of the parameter that defines the size of the cross-section of at least a part of the pipe along the second direction, and the value of the parameter that defines the thickness of the wall of at least a part of the pipe may be regarded to be equivalent to setting a value of a parameter that defines the inner diameter of the pipe and the value of the parameter that defines the outer diameter of the pipe. Alternatively, the parameter setting GUI 911pi #4 may include a parameter setting GUI 911 for directly setting the value of the parameter that defines the inner diameter of at least a part of the pipe. The parameter setting GUI 911pi #4 may include a parameter setting GUI 911 for directly setting the value of the parameter that defines the outer diameter of at least a part of the pipe.
As illustrated in
Incidentally, in the above-described example, when each of the size of at least a part of the pipe and the rotational angle of at least a part of the pipe each changes, the shape of the cross-section of at least a part of the pipe changes. Thus, each of the parameter that defines the size of at least a part of the pipe and the parameter that defines the rotational angle of at least a part of the pipe may be referred to as a cross-sectional parameter (a section parameter) related to the cross-section of at least a part of the pipe.
As illustrated in
As illustrated in
As illustrated in
Incidentally, in the above-described example, the presence or absence of the branch, the presence or absence of the merge, and the multiple structure of at least a part of the pipe are all related to the structure of the pipe. Thus, each of the parameter that defines the presence or absence of the branch of at least a part of the pipe, the parameter that defines the presence or absence of the merge of at least a part of the pipe, and the parameter that defines the multiple structure of at least a part of the pipe may be referred to as a structural parameters related to the structure of at least a part of the pipe.
As illustrated in
In the present example embodiment, the shapes of the cross-section of the pipe at each of the positions of the plurality of points P through which the pipe passes are used as the shape of the cross-section of at least a part of the pipe. Specifically, when the pipe passes from the start point Po through the intermediate points P1 and P2 in sequence to thereby reach the end point Pe as illustrated in
Incidentally, in the above-described example, each of the size of at least a part of the pipe, the rotational angle of at least a part of the pipe, and the type of the shape of the cross-section of at least a part of the pipe each changes, the shape of the cross-section of at least a part of the pipe changes. Thus, each of the parameter that defines the size of at least a part of the pipe, the parameter that defines the rotational angle of at least a part of the pipe, and the type of the shape of the cross-section of at least a part of the pipe may be referred to as the cross-sectional parameter (the section parameter) related to the cross-section of at least a part of the pipe.
The terminal user may set the shape information by using at least one of the parameter setting GUI 911 and the icon selection GUI 912 so that the shapes of the cross-sections of the pipe at the plurality of points P through which the pipe passes are all the same type of shapes. Note that the “type of shape” here may mean, for example, a type of shape of the cross-section that is allowed to be selected by using the icon selection GUI 912pi #1. Thus, a state in which the shapes of the cross-sections of the pipe at the plurality of points P are all the same type of shape may mean a state in which the shapes of the cross-sections of the pipe at the plurality of points P are set to one type of shape associated with one icon.
Alternatively, the terminal user may set the shape information by using at least one of the parameter setting GUI 911 and the icon selection GUI 912 so that the shapes of the cross-sections of the pipe at at least two of the plurality of points P through which the pipe passes are different types of shapes. Note that a state in which the shapes of the cross-sections of the pipe at at least two points P are different types of shapes may mean a state in which the shape of the cross-section of the pipe at a first point P is set to be a first type of shape associated with a first icon and the shape of the cross-section of the pipe at a second point P is set to be a second type of shape associated with a second icon. For example, the terminal user may set the shape of the cross-section of the pipe at the first point P (for example, any one of the start point Po, the intermediate point P1, the intermediate point P2, and the end point Pe) among the plurality of points P through which the pipe passes to be a first shape (for example, a rectangular shape) and set the shape of the cross-section of the pipe at the second point P (for example, other one of the start point Po, the intermediate point P1, the intermediate point P2, and the end point Pe) to be a second shape (for example, a circular shape) that is different from the first shape. In this case, the shape of the cross-section of the pipe changes from the first shape to the second shape between the first point P and the second point P. Therefore, the output screen 92 may also display the three-dimensional model of the pipe in which the shape of the cross-section changes from the first shape to the second shape between the first point P and the second point P. For example, when the shape information is set so that the shape of the cross-section of the pipe at the first point P is the first shape and then the shape information is set so that the shape of the cross-section of the pipe at the second point P is the second shape, a model part of the three-dimensional model, which is displayed on the output screen 92, between the first point P and the second point P may be updated. More specifically, for example, when the value of the parameter is set so that the shape of the cross-section of the pipe at the first is the first shape and then the value of the parameter is set so that the shape of the cross-section of the pipe at the second point P is the second shape, the model part of the three-dimensional model, which is displayed on the output screen 92, between the first point P and the second point P (especially, the shape of this model part) may be updated depending on the setting of the value of the parameter that defines the shape of the pipe at the second point P2. For example, when the icon is selected so that the shape of the cross-section of the pipe at the first is the first shape and then the icon is selected so that the shape of the cross-section of the pipe at the second point P is the second shape, the model part of the three-dimensional model, which is displayed on the output screen 92, between the first point P and the second point P (especially, the shape of this model part) may be updated depending on the selection of the icon to set the shape of the pipe at the second point P. However, not only in a case where the shapes of the cross-sections of the pipe at at least two of the plurality of points P are different types of shapes but also in a case where the shape information is set so that the shape of the cross-section of the pipe at the first point P is the first shape and then the shape information is set so that the shape of the cross-section of the pipe at the second point P is the second shape, the model part of the three-dimensional model, which is displayed on the output screen 92, between the first point P and the second point P (especially, the shape of this model part) may be updated

Next,
As illustrated in
The parameter setting GUI 911pl #1 may include a parameter setting GUI 911pl #11 for setting a value of a parameter that defines a position of the hole H (namely, a position of the cylindrical part CM). For example, as illustrated in
The parameter setting GUI 911pl #1 may include a parameter setting GUI 911pl #12 for setting a value of a parameter that defines a depth of the hole H (namely, a size of the hole H along the thickness direction of the plate, and it is equivalent to a height of the cylindrical part CM along the thickness direction of the plate). For example, as illustrated in
The parameter setting GUI 911pl #1 may include a parameter setting GUI 911pl #13 for setting a value of a parameter that defines a type of shape of the inner surface facing the hole H (namely, the inner surface of the cylindrical part CM). For example, as illustrated in
The parameter setting GUI 911pl #1 may include a parameter setting GUI 911pl #14 for setting a value of a parameter that defines a diameter of the hole H (namely, a size of the hole H in the direction along the surface of the plate, and it is equivalent to a size of the cylindrical part CM in the direction along the surface of the plate). For example, as illustrated in
As illustrated in
The parameter setting GUI 911pl #2 may include a parameter setting GUI 911pl #21 for setting a value of a parameter that defines a position of the rib part R. For example, as illustrated in
The parameter setting GUI 911pl #2 may include a parameter setting GUI 911pl #22 for setting a value of a parameter that defines a width of the rib part R (namely, a size of the rib part R in a direction that is along the surface of the plate and that intersects with the direction along which the rib part R extends). For example, as illustrated in
The parameter setting GUI 911pl #2 may include a parameter setting GUI 911pl #23 for setting a value of a parameter that defines a height of the rib part R (namely, a size of the rib part R along the thickness direction of the plate). For example, as illustrated in
As illustrated in
As described above, the plate may include the plurality of base parts B (see
As illustrated in
The parameter setting GUI 911pl #3 may include a parameter setting GUI 911pl #31 for setting a value of a parameter that defines a pitch of the base structure BS that constitutes the base part B. For example, as illustrated in
The parameter setting GUI 911pl #3 may include a parameter setting GUI 911pl #32 for setting a value of a parameter that defines a width of the base structure BS that constitutes the base part B (namely, a size of the base structure BS in a direction along the surface of the plate, specifically, a size of rib-shaped part in a direction that is along the surface of the plate and that intersects with a direction along which the rib-shaped part, which constitutes the base structure BS, extends). For example, as illustrated in
The parameter setting GUI 911pl #3 may include a parameter setting GUI 911pl #33 for setting a value of a parameter that defines a height of the base structure BS that constitutes the base part B (namely, a size of the base structure BS along the thickness direction of the plate). For example, as illustrated in
Again in
As a result of the determination at the step S15, when it is determined that the operation of setting the shape information using the setting GUI 9 has not been completed (the step S15: No), the operation of setting the shape information using the setting GUI 9 is continued. Namely, the build system SYS continues the operation from the step S13 to the step S14.
On the other hand, when it is determined that the operation of setting the shape information using the setting GUI 9 has been completed (the step S15: Yes), the data generation unit 213 generates, based on the latest shape information obtained by the information obtaining unit 212 at the step S13, the three-dimensional model of the three-dimensional structural object having the shape defined by the shape information set by the terminal user (a step S16).
The format of the three-dimensional model data may be any format. For example, the data generation unit 213 may generate the three-dimensional model data compliant with a STL (Standard Triangulated Language) file format. For example, the data generation unit 213 may generate the three-dimensional model data compliant with a STEP (Standard for Exchange of Product Model Data) file format. For example, the data generation unit 213 may generate the three-dimensional model data compliant with an IGES (Initial Graphics Exchange Specification) file format. For example, the data generation unit 213 may generate the three-dimensional model data compliant with ta DWG file format. For example, the data generating unit 213 may generate the three-dimensional model data compliant with a DXF (Drawing Exchange Format) file format. For example, the data generating unit 213 may generate the three-dimensional model data compliant with a VRML (Virtual Reality Modeling Language) file format. For example, the data generating unit 213 may generate the three-dimensional model data compliant with an ISO 10303 file format.
The data generation unit 213 may store the generated three-dimensional model data in the storage apparatus 22. Alternatively, the data generation unit 213 may store, in addition to or instead of the generated three-dimensional model data, the shape information used to generate the three-dimensional model data (namely, the shape information such as the parameter set by the terminal user) in the storage apparatus 22. When the storage apparatus 22 stores the shape information, the data generation unit 213 may generate the three-dimensional model data based on the shape information stored in the storage apparatus 22. The data generation unit 213 may regenerate (namely, restore) the generated three-dimensional model data based on the shape information stored in the storage apparatus 22. The data generation unit 213 may generate, based on the restored three-dimensional model data, new three-dimensional model data representing a new three-dimensional structural object that is obtained by adding a new part (for example, a screw part and the like) to the three-dimensional structural object represented by the restored three-dimensional model data. Namely, the data generation unit 213 may modify the restored three-dimensional model data.
Moreover, the data generation unit 213 may store the set shape information in the storage apparatus 22 after it is determined that the operation of setting the shape information using the setting GUI 9 has been completed. The data generation unit 213 may also store the shape information that has been set up to that time (the shape information in the process of being set) in the storage apparatus 22 before it is determined that the operation of setting the shape information using the setting GUI 9 has been completed. For example, the data generation unit 213 may store the shape information that has been set up to that time (the shape information in the process of being set) in the storage apparatus 22 when the terminal user wants to temporarily suspend the operation of setting the shape information using the setting GUI 9, although the operation of setting the shape information using the setting GUI 9 has not been completed. In this case, when the terminal user resumes setting the shape information, the display control unit 211 may display on the display apparatus 35 the setting GUI 9 used by the terminal user to continue setting the shape information from where he suspended based on the shape information in the process of being set.
Then, the data generation unit 213 transmits the three-dimensional model data generated at the step S16 to the build apparatus 1 by using the communication apparatus 23. Note that the data generation unit 213 may transmit the three-dimensional model data to the build apparatus 1 based on an instruction from the server user (alternatively, the terminal user or the build user). Alternatively, the data generation unit 213 may automatically transmit the three-dimensional model data to the build apparatus 1 without waiting for the instruction from the server user (alternatively, the terminal user or the modeling user). The control apparatus 17 of the build apparatus 1 receives (obtains) the three-dimensional model data transmitted from the data generation server 2 by using the communication apparatus 18. Then, the control apparatus 17 generates the build control information that specifies a detail of the operation of the build apparatus 1 based on the three-dimensional model data (a step S18). Specifically, the control apparatus 17 generates, based on the three-dimensional model data, the build control information that specifies a detail of the operation of the build apparatus 1 to build the three-dimensional structural object represented by the three-dimensional model data (namely, the three-dimensional structural object having a shape defined by the shape information set by the terminal user). Namely, the control apparatus 17 generates, based on the three-dimensional model data, the build control information that allows the build apparatus 1 to operate to build the three-dimensional structural object represented by the three-dimensional model data.
The build control information may include path information that indicates a moving trajectory of the processing head 121 relative to the stage 131. As the processing head 121 moves, an irradiation position of the processing light EL from the irradiation optical system 1211 and a supply position of the build materials M from the material nozzle 1212 also move. Thus, the path information may be regarded to indicate a movement trajectory of each of the irradiation position of the processing light EL and the supply position of the build materials M relative to the stage 131.
Then, the control apparatus 17 controls the operation of the build apparatus 1 to build the three-dimensional structural object (namely, the three-dimensional structural object having the shape set by the terminal user) based on the build control information (the step S18). As a result, the three-dimensional structural object having the shape set by the terminal user is built.
Note that a control information generation apparatus that is different from the control apparatus 17 of the build apparatus 1 may generate the build control information. In this case, the data generation unit 213 may transmit the three-dimensional model data generated at the step S16 to the control information generation apparatus. The control information generation apparatus 17 may receive (obtain) the three-dimensional model data transmitted from the data generation server 2. Then, the control information generation apparatus may generate the build control information based on the three-dimensional model data. Then, the control information generation apparatus may transmit the generated build control information to the build apparatus 1 (the control apparatus 17). Then, the control apparatus 17 may control the operation of the build apparatus 1 based on the build control information generated by the control information generation apparatus.
As described above, in the build system SYS in the present example embodiment, the terminal user can generate the three-dimensional model data by setting the value of the parameter and/or selecting the icon that defines the shape of the three-dimensional structural object. Namely, the terminal user can generate the three-dimensional model data without using a software that requires highly specialized knowledge such as a three-dimensional CAD (Computer Aided Design) software. Namely, the data generation server 2 is capable of appropriately assisting the user to generate the three-dimensional model data by providing the setting GUI 9 to the terminal user.
Especially, the data generation server 2 provides, to the terminal user, the setting GUI 9 according to the type of the three-dimensional structural object so that the terminal user can set appropriate shape information according to the type of the three-dimensional structural object to be additively built by the build apparatus 1. Thus, the terminal user can generate the three-dimensional model data regardless of the type of the three-dimensional structural object. For example, the terminal user can generate the three-dimensional model data representing the three-dimensional model of the three-dimensional structural object including at least one of the pipe and the plate.
Moreover, the terminal user can intuitively generate the three-dimensional model data because the three-dimensional model based on the shape information currently set by the terminal user is displayed on the output screen 92 included in the setting GUI 9.
As described above, the terminal user may use the setting GUI 9 to set the shape information related to the shape of the three-dimensional structural object as desired by the terminal user. Specifically, the terminal user may use the parameter setting GUI 911 to set the parameter that defines the shape of the three-dimensional structural object to be the terminal user's desired setting values. The terminal user may use the icon selection GUI 912 to set the shape of the three-dimensional structural object to be the terminal users desired shape (namely, the specific shape associated with the icon selected by the terminal user).
On the other hand, depending on the setting value of the shape information, there is a possibility that the three-dimensional structural object having the shape defined by the shape information set by the terminal user does not satisfy a predetermined shape conditions related to the shape of the three-dimensional structural object. Such a condition that “the shape of the three-dimensional structural object (namely, the shape of the three-dimensional model represented by the three-dimensional model data generated based on the shape information) is a shape that can be built by the build apparatus 1 is one example of the predetermined shape condition. Thus, when the three-dimensional structural object having the shape defined by the shape information does not satisfy the shape condition, there is a possibility that the build apparatus 1 is not capable of building the three-dimensional structural object having the shape defined by the shape information. Note that least one of a reason that at least a part of the build object constituting the three-dimensional structural object interferes with the build apparatus 1 in the process of building the three-dimensional structural object, a reason that at least a part of the build object constituting the three-dimensional structural object prevents the build apparatus 1 from irradiating a desired irradiation position with the processing light EL in the process of building the three-dimensional structural object, and a reason that at least a part of the build object constituting the three-dimensional structural object prevents the build apparatus 1 from supply the build materials M to a desired supply position in the process of building the three-dimensional structural object is one example of a reason why the build apparatus 1 is not capable of building the three-dimensional structural object. All of the reasons are related to at least the build apparatus 1. Thus, the shape condition may be regarded as an example of a constraint condition related to the build apparatus 1.
Moreover, depending on the setting value of the shape information, there is a possibility that the three-dimensional structural object having the shape defined by the shape information set by the terminal user does not satisfy a predetermined strength condition related to a strength of the three-dimensional structural object. Such a condition that “the strength of the three-dimensional structural object built to have the shape defined by the shape information is higher than a predetermined strength which the three-dimensional structural object should have is one example of the strength condition. Thus, when the three-dimensional structural object having the shape defined by the shape information does not satisfy the strength condition, there is a possibility that the strength of the built three-dimensional structural object is lower than the predetermined strength which the three-dimensional structural object should have, although the build apparatus 1 is capable of building the three-dimensional structural object. Namely, there is a possibility the strength of the three-dimensional structural object is insufficient. Note that a reason that the shape of the three-dimensional structural object is a shape by which the strength of the three-dimensional structural object cannot be maintained is one example of a reason why the strength of the three-dimensional structural object is insufficient. This reason is a reason related to at least the three-dimensional structural object. Thus, the strength condition may be regarded as an example of a constraint condition related to the three-dimensional structural object.
Moreover, depending on the setting value of the shape information, there is a possibility that the three-dimensional structural object having the shape defined by the shape information set by the terminal user does not satisfy a predetermined quality conditions related to a quality of the three-dimensional structural object. Here, the quality of the three-dimensional structural object may include a processing quality of the three-dimensional structural object. When the processing quality of the three-dimensional structural object is not relatively good, an error between a characteristic (for example, at least one of size, shape, and weight) of the three-dimensional structural object and an expected characteristic is larger, compared to a case where the processing quality of the three-dimensional structural object is relatively good. Such a condition that “the quality of the three-dimensional structural object that is built to have the shape defined by the shape information is higher than a predetermined quality which the three-dimensional structural object should have is one example of the quality condition. Thus, when the three-dimensional structural object having the shape defined by the shape information does not satisfy the quality condition, there is a possibility that the quality of the built three-dimensional structural object is lower than the predetermined quality which the three-dimensional structural object should have, although the build apparatus 1 is capable of building the three-dimensional structural object. Namely, there is a possibility that the quality of the three-dimensional structural object is lower than expected. A reason that the shape of the three-dimensional structural object is a shape by which the processing quality of the three-dimensional structural object cannot be maintained is one example of a reason why the quality of the three-dimensional structural object is lower. This reason is a reason related to at least the three-dimensional structural object. Thus, the quality condition may be regarded as an example of a constraint condition related to the three-dimensional structural object.
Therefore, in the modified example, the data generation server 2 may assist the terminal user setting the shape information in a period during which the terminal user sets the shape information so that the three-dimensional structural object having the shape defined by the shape information properly satisfies at least one of the shape condition, the strength condition, and the quality condition. Specifically, the data generation server 2 may perform a first assist processing for present, to the terminal user, allowable shape information related to an allowable shape, wherein the allowable shape is a shape which the terminal user is allowed to set as the shape of the three-dimensional structural object. Furthermore, in addition to or instead of the first assist processing, the data generation server 2 may perform a second assist processing for prompting the terminal user to set the shape information again when the three-dimensional structural object having the shape defined by the shape information does not satisfy at least one of the shape condition, the strength condition, and the quality condition. Next, the first assist processing and the second support processes are described below in order.
Firstly, the first support processing for presenting, to the terminal user, the allowable shape information related to the allowable shape, wherein the allowable shape is the shape which the terminal user is allowed to set as the shape of the three-dimensional structural object, will be described.
The allowable shape corresponds to a shape of the three-dimensional structural object in a state that satisfies at least one of the shape condition, the strength condition, and the quality condition. Thus, the allowable shape may include a shape of the three-dimensional structural object that can be built by the build apparatus 1. The allowable shape may include a shape of the three-dimensional structural object having a strength that is equal to or higher than the predetermined strength. The allowable shape may include a shape of the three-dimensional structural object having a quality that is equal to or higher than the predetermined quality.
The allowable shape is determined based on at least one of the shape condition, the strength condition, and the quality condition. Thus, the allowable shape information may be determined in advance based on one of the shape condition, the strength condition, and the quality condition. Alternatively, there is a possibility that the allowable shape changes due to a change of the shape of the three-dimensional structural object in the process of the terminal user setting the shape information. Therefore, the allowable shape information may be generated or changed based on the shape information that has been set by the terminal user and one of the shape condition, the strength condition, and the quality condition. In both cases, the allowable shape easily calculatable from at least one of the shape condition, the strength condition, and the quality condition (furthermore, the shape information that has been set by the terminal user), because the allowable shape is determined based on the characteristic of the build apparatus 1 and a characteristic of the three-dimensional structural object.
As described above, the terminal user sets the shape information on the setting GUI 9 (especially, the input screen 91). Thus, the data generation server 2 (especially, the display control unit 211, the same is applied to the below-described description) may present, to the terminal user, the allowable shape information related to the allowable shape on the setting GUI 9 (especially, the input screen 91).
For example, as described above, the terminal user uses the parameter setting GUI 911 to set the value of the parameter that defines the shape of the three-dimensional structural object. In this case, the allowable shape information may include allowable parameter information indicating at least one of candidate value and range of the parameter which the terminal user is allowed to set. For example, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 that includes the allowable parameter information indicating at least one of the candidate value and range of the parameter that defines the shape of the three-dimensional structural object satisfying the shape condition. Specifically, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable parameter information indicating at least one of the candidate value and range of shape parameter that defines the shape of the three-dimensional structural object that can be built by the build apparatus 1. The data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 that includes the allowable parameter information indicating at least one of the candidate value and range of the shape parameter that defines the shape of the three-dimensional structural object satisfying the strength condition. Specifically, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable parameter information indicating at least one of the candidate value and range of the shape parameter that defines the shape of the three-dimensional structural object having the strength equal to or higher than the predetermined strength. The data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable parameter information indicating at least one of the candidate value and range of the shape parameter that defines the shape of the three-dimensional structural object satisfying the quality condition. Specifically, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable parameter information indicating at least one of the candidate value and range of the shape parameter that defines the shape of the three-dimensional structural object having the quality equal to or higher than the predetermined quality.
For example, as described above, the terminal user uses the icon selection GUI 912 to set the shape information related to the shape of the three-dimensional structural object. In this case, the allowable shape information may include allowable icon information indicating the icon which the terminal user is allowed to select. For example, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 that includes the allowable icon information indicating the icon associated with the shape of the three-dimensional structural object satisfying the shape condition. Specifically, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable icon information indicating the icon associated with the shape of the three-dimensional structural object that can be built by the build apparatus 1. The data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable icon information indicating the icon associated with the shape of the three-dimensional structural object satisfying the strength condition. Specifically, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable icon information indicating the icon associated with the shape of the three-dimensional structural object having the strength equal to or higher than the predetermined strength. The data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable icon information indicating the icon associated with the shape of the three-dimensional structural object satisfying the quality condition. Specifically, the data generation server 2 may control the terminal apparatus 3 to display the setting GUI 9 including the allowable icon information indicating the icon associated with the shape of the three-dimensional structural object having the quality equal to or higher than the predetermined quality.
As illustrated in
A presentation aspect (a display aspect) of the allowable shape information may be selected by the terminal user. For example, the setting GUI 9 including the allowable parameter information displayed in the display aspect selected by the terminal user may be displayed. For example, the setting GUI 9 including the allowable icon information displayed in the display aspect selected by the terminal user may be displayed. As one example, when the terminal user desires the display of the allowable icon information in the display aspect illustrated in
A presence or absence of the presentation (a presence or absence of the display) of the allowable shape information may be designated by the terminal user. For example, when the terminal user does not desire the display of the allowable shape information, the setting GUI 9 that does not include the allowable shape information may be displayed. For example, when the terminal user desires the display of the allowable shape information, the setting GUI 9 that includes the allowable shape information may be displayed.
When the setting GUI 9 including the allowable shape information is displayed, the terminal user can not only recognize the allowable shape, but may also recognize that a shape different from the allowable shape is a shape that does not satisfy at least one of the shape condition, the strength condition and the quality condition (hereinafter, it is referred to as a “disallowed shape”) based on the allowable shape information. For example, when the setting GUI 9 including the allowable parameter information is displayed, the terminal user can not only recognize at least one of the candidate value and range of parameter which the terminal user is allowed to set, but also recognize at least one of the value and range of the parameters which the terminal user is not allowed to set (namely, at least one of the value and range of the parameter defining the shape that does not satisfy at least one of the shape condition, the strength condition, and the quality condition) based on the allowable parameter information. For example, when the setting GUI 9 including the allowable icon information is displayed, the terminal user can not only recognize not only the icon which the user is allowed to select, but also recognize the icon which the terminal user is not allowed to select (namely, the icon associated with the shape that does not satisfy at least one of the shape condition, the strength condition, and the quality condition) based on the allowable icon information. Thus, the operation of presenting the allowable shape information to the terminal user may be regarded to be substantially equivalent to an operation of presenting disallowed shape information related to the disallowed shape to the terminal user.
Alternatively, the data generation server 2 may actively present the disallowed shape information to the terminal user. For example, as illustrated in
When the above-described first assist processing is performed, the terminal user can easily recognize the allowable shape. Thus, the terminal user can set the shape information so that the three-dimensional structural object having the shape defined by the shape information set by the terminal user properly satisfies at least one of the shape condition, the strength condition, and the quality condition. As a result, there is a lower possibility that the shape information is set again, compared to a case where it is found out only after the terminal user has finished setting the shape information that the three-dimensional structural object having the shape defined by the shape information set by the terminal user does not properly satisfy at least one of the shape condition, the strength condition, and the quality condition. Thus, the terminal user can set the shape information efficiently.
Next, the second assist processing for prompting the terminal user to set the shape information again when the three-dimensional structural object having the shape defined by the shape information does not satisfy at least one of the shape condition, the strength condition, and the quality condition.
As described above, the terminal user sets the shape information on the setting GUI 9 (especially, the input screen 91). Thus, the data generation server 2 (especially, the display control unit 211, the same is applied to the below-described description) may perform a processing for prompting the terminal user to set the shape information again on the setting GUI 9 (especially, the input screen 91).
For example, as described above, the terminal user uses the parameter setting GUI 911 to set the value of the parameter that defines the shape of the three-dimensional structural object. In this case, when the terminal user sets the value of the parameter which the terminal user is not allowed to set (namely, the value of the parameter defining the shape that does not satisfy at least one of the shape condition, the strength condition, and the quality condition), the data generation server 2 may perform the process for prompting the terminal user to set the value of the parameter again on the setting GUI 9. For example, as illustrated in
For example, as described above, the terminal user uses the icon selection GUI 912 to set the shape information related to the shape of the three-dimensional structural object. In this case, when the terminal user selects the icon which the terminal user is not allowed to select (namely, the icon associated with the shape that does not satisfy at least one of the shape condition, the strength condition, and the quality condition), the data generation server 2 may perform the process for prompting the terminal user to select the icon again on the setting GUI 9. For example, as illustrated in
Alternatively, in addition to or instead of displaying the message window 918, the data generation server 2 may display the setting GUI 9 so that the value of the parameter which the terminal user is not allowed to set cannot be set (namely, cannot be inputted) on the setting GUI 9. For example, as illustrated in
Similarly, in addition to or instead of displaying the message window 918, the data generation server 2 may display the setting GUI 9 so that the terminal user cannot select the icon which the terminal user is not allowed to select on the setting GUI 9. In this case, the terminal user recognizes that the icon that should have been selected is not selected (namely, the selection of the icon is not completed) and thus, recognizes that the icon needs to be selected again.
When the above-described second assist processing is performed, the terminal user can easily determine whether or not the shape information set by the terminal user defines the shape that does not satisfy at least one of the shape condition, the strength condition, and the quality condition. Thus, the terminal user can set the shape information so that the three-dimensional structural object having the shape defined by the shape information set by the terminal user properly satisfies at least one of the shape condition, the strength condition, and the quality condition. As a result, there is a lower possibility that the shape information is set again, compared to a case where it is found out only after the terminal user has finished setting the shape information that the three-dimensional structural object having the shape defined by the shape information set by the terminal user does not properly satisfy at least one of the shape condition, the strength condition, and the quality condition. Thus, the terminal user can set the shape information efficiently.
The build apparatus 1 may include a display apparatus that is configured to display the setting GUI 9 (namely, an apparatus that is configured to serve as the display apparatus 35 of the terminal apparatus 3). The build apparatus 1 may include an input apparatus that is used by the build user to operate the setting GUI 9 (namely, an apparatus that is configured to serve as the input apparatus 34 of the terminal apparatus 3). Namely, the build apparatus 1 may include at least a part of the terminal apparatus 3. In this case, the build user may set the shape information by using the setting GUI 9. Furthermore, in this case, the control apparatus 17 of the build apparatus 1 may generate the three-dimensional model data based on the shape information set by the build user. Namely, the control apparatus 17 may include at least a part of the data generation server 2.
In the above-described description, the display apparatus 35 of the terminal apparatus 3 displays the setting GUI 9 including both of the input screen 91 and the output screen 92. However, the display apparatus 35 may display either one of the input screen 91 and the output screen 92 and may not display the other one of the input screen 91 and the output screen 92. Namely, a display mode of the display apparatus 35 may be switched between a mode in which both of the input screen 91 and the output screen 92 are displayed and a mode in which either one of the input screen 91 and the output screen 92 is displayed. In this case, the display mode of the display apparatus 35 may be switched based on the terminal user's instruction.
In the above-described description, the build apparatus 1 melts the build material M by irradiating the build material M with the processing light EL. However, the build apparatus 1 may melts the build material by irradiating the build material M with any energy beam. At least one of a charged particle beam, an electromagnetic wave and the like is one example of any energy beam. At least one of an electron beam, an ion beam and the like is one example of the charged particle beam.
In the above-described description, the build apparatus 1 builds the three-dimensional structural object by performing the additive processing based on the Laser Metal Deposition. However, the build apparatus 1 may build the three-dimensional structural object by performing the additive processing based on another method by which the three-dimensional structural object is formable. Alternatively, the build apparatus 1 may build the three-dimensional structural object by performing a removal processing, in addition to or instead of performing the additive processing. The build apparatus 1 may build the three-dimensional structural object by performing a machining processing, in addition to or instead of performing at least one of the additive processing and the removal processing.
