Solid freeform fabrication systems have been used to fabricate solid three-dimensional structures using a few materials. At present, the structures are either made from pre-processed materials or processed after the entire structure is made. In various applications, including the food industry, materials are sometimes required to be processed before additional layers of materials are added. Accordingly, there is a need for methods and systems for solid freeform fabrication of edible foods.
Technologies are provided herein for processing edible materials using tools associated with a fabrication system. In one aspect, a fabricator includes a control module and a drive assembly controlled by the control module. The fabricator also includes at least one food processing tool head coupled to the drive assembly that can process material for fabricating an edible structure on a build surface.
In another aspect, a soft-shelled packet containing a material includes a soft outer shell having an outer surface, and an outlet through which the material is dispensed upon a force being applied to the outer surface, wherein the soft-shelled packet is sized to be received within a food processing tool head of a fabricator.
In yet another aspect, a fabricator includes a control module and a drive assembly controlled by the control module. The fabricator further includes at least one detachable food processing tool head configured to couple with the drive assembly. The tool head includes a housing for holding a soft-shelled packet comprising material, an actuation mechanism for dispensing material from the soft-shelled packet, an outlet for depositing the dispensed material to a build surface, and a food processing component configured to process the dispensed material deposited on the build surface via the outlet.
Technologies are provided herein for processing edible materials using tools associated with a fabrication system. By way of the present disclosure, solid edible materials may be grated, sliced, chopped, and deposited over a designated portion of a build surface or over the entire surface. Powdered material may also be deposited. Furthermore, materials being deposited may also be processed as a layer of material is being deposited, or in some embodiments, before, between or after layers of materials have been deposited. Examples of processing operations include, but are not limited to, heating, frying, cooling, humidifying, and supplying hot air or other gases. Furthermore, providing ultraviolet light or maintaining the fabricator in an anaerobic environment can keep the environment sterile, preventing the edible materials from being contaminated. Although edible materials may be used, it should be appreciated that the present disclosure is not limited to edible materials.
Further technologies are provided herein for a soft packet container for storing materials. The soft packet material may be flat, or accordion-shaped. In various embodiments, the soft packets may dispense material by applying a mechanical force or a pneumatic force. Details of the soft packets and the dispensing mechanisms are also provided herein.
The present disclosure will be more completely understood through the following description, which should be read in conjunction with the drawings. In this description, like numbers refer to similar elements within various embodiments of the present disclosure. Within this description, the claims will be explained with respect to embodiments. The skilled artisan will readily appreciate that the methods, apparatus and systems described herein are merely exemplary and that variations can be made without departing from the spirit and scope of the disclosure.
Co-pending PCT patent application entitled “DEPOSITION TOOL WITH INTERCHANGEABLE MATERIAL BAY”WIPO publication W02012103007) and co-pending U.S. Utility patent application entitled “SYSTEMS AND METHODS FOR FREEFORM FABRICATION OF FOAMED STRUCTURES”U.S. Pat Publication 20120241993) both filed on Jan. 23, 2012 having first named inventor Jeffrey Lipton are hereby incorporated by reference in their entirety and for all purposes. In addition, issued U.S. Pat. No. 7,625,198 entitled “MODULAR FABRICATION SYSTEMS AND METHODS” is also hereby incorporated by reference in its entirety and for all purposes,
Referring now to the figures, FIG. I is a pictorial representation of a three dimensional fabrication system for fabricating a structure according to embodiments of the present disclosure. The three dimensional fabrication system 100 comprises a fabricator 102 having at least one fabrication tool head 104 that is controlled by a control unit 106. In various embodiments, the control unit 106 may include a drive assembly that is configured to receive modular fabrication tool heads, such as the tool head 104, and control the movement of the modular tool head 104 such that the tool head 104 can either deposit or process material at any particular portion of a surface on which the structure is being fabricated. In various embodiments, the drive assembly includes a gantry mechanism for moving the tool head over an entire build surface.
The control unit 106 may be configured to receive instructions from a processing unit 120. The processing unit 120 includes, but is not limited to, a processor 122, a memory 124, and a fabrication software application 126, which is executable by the processor 122. The fabrication software application 126 is configured to provide instructions to the control unit 106 to cause the fabricator 102 to perform particular functions to prepare fabricated structures. In some embodiments, these fabricated structures may be related to edible materials, while the functions being performed by the fabricator may include functionality that processes the materials to make them edible. As will be described in further detail below, some of these functions may entail processing one or more layers of the materials as they are printed.
Referring now to
An edible solid material 202 may be driven towards an oscillating grating tool head 204 causing the grating tool head 204 to grate the solid material 202 via a grating surface 206 of the grating tool head 204. As the edible material is driven towards the grating surface 206, the material 202 is processed into the desired form and distributed across the target surface. For example, a block of solid cheese could be driven down towards the oscillating grating surface 206, which grates the cheese such that the grated cheese applies an even coating, while the tool head 204 and grating surface 206 moves across the build surface. Similarly, a stick of butter could move down a prescribed amount, and then a slicing mechanism could slide across the exposed portion to deposit it across the surface. In various embodiments, the material can be driven down using a roller based mechanism, as shown in
Referring now to
In various embodiments, the fabricator may be configured to process materials after they are deposited on the build surface. For instance, after depositing grated cheese on the surface, there may be a desire to supply hot air to melt the grated cheese. Upon heating the cheese, there may be a desire to rapidly cool the heated cheese. These processes may be performed using food processing tool heads, such as those shown in
The tool head 700 is configured to receive hot oil from a first end and deliver the hot oil on the build surface via the outlet 708. The outlet 708 may be configured to deliver the oil in one or more different forms, including, but not limited to spraying the oil, pouring the oil or squirting the oil. If located on a material deposition tool head, such as shown in
It should be appreciated that the hot oil can be sprayed on a particular portion of the build surface or materials covering a portion of the build surface for localized frying of foods. Further, using this mechanism for dispensing hot oil allows for controlling the crispness of a food throughout the printed or fabricated structure.
As described above, the supply pipes and corresponding outlets can be mounted as an independent tool head, or collocated with the deposition tool head. If collocated, the supply pipe may be placed on a rotary track around the deposition nozzle to allow the pipe to move along the path of the deposition nozzle. In some embodiments, the heat source could be a combination or radiative, convective or conductive head transfer sources. For example, a microwave emitter could be located on a tool head, or a high powered infra-red source could be used. A heated air source could be used for convection heating. All of the sources may be more intense than traditional cooking heat sources, reaching higher temperatures to cause the reactions of cooking to take place more quickly, allowing the heat exposure to be briefer. The higher the temperature, the faster the tool head could move ensuring the entire object is heated and cooked evenly throughout the machine.
In
Food being fabricated or prepared can be sterilized by exposing the food to an ultraviolet source. This can be accomplished by having a single UV light source in the build chamber which can expose the entire exposed surface at once. In various embodiments, an IR light source may be used in a similar fashion to induce chemical reactions in the deposited material/s. Another method would include a UV light source which extends the length of an axis of the exposed surface and is scanned across the perpendicular axis, as shown in
Referring now to
In some embodiments, the packet may include an opening fitted with a one way valve or filter to prevent back flow of the material. The fluid stored in the packet could be dispensed using several methods. A displacement mechanism would regulate the volume of material extruded by having the mechanism deform the packet by a prescribed volume to ensure the equivalent volume of material is ejected into the fluid flow path. For instance, with respect to
In various embodiments, the packets could contain an identifier for identifying the contents to be deposited on the surface. In this way, the fabrication system 100 may automatically fabricate an entire structure by automatically identifying a material packet that contains the proper material for deposition.
While the foregoing includes the best mode and, where appropriate, other modes of performing the disclosure, the disclosure should not be limited to specific apparatus configurations or method steps disclosed in this description of the preferred embodiment. Those skilled in the art will also recognize that the disclosure has a broad range of applications, and that the embodiments admit of a wide range of modifications without departing from the inventive concepts.
