Not Applicable
The present systems, apparatuses, and methods lie in the field of funerary urns, devices, and memorials, in addition to three-dimensional printing/additive manufacturing, ecological design, and industrial design of same. The present disclosure relates to systems and methods for designing, fabricating, and using cremated remains and composite material in combination to form a type of decorative memorial or biodegradable burial urn.
While cremation has been popular in parts of the world for centuries, it is only now just gaining traction as the soon-to-be most popular choice for internment of the deceased in the West. The cremains or ashes are commonly either spread out, such as at sea, or kept in an urn. Traditionally, an urn is any funerary receptacle charged with the responsibility of holding or containing the ashes of the deceased, be it an animal, pet, or human being.
There are a number of precedents for customizable memorial and burial urns for cremains. They range from photorealistic containers to configurable designs that accommodate anything from the ashes to memorial items. There exists several patents for the apparatus and method of burying a container holding human or pet cremains that eventually disintegrate either in water and/or render seed/plant growth. Recently there have been several patents for the combination of cremains, and a material like glass to capture both the ashes of the deceased as well as, but not limited to, a personal memento or mark to memorialize the deceased.

Thus, a need exists to overcome the problems with the prior art systems, designs, and processes as discussed above.
The systems, apparatuses, and methods described provide funerary devices and systems and method for creating funerary devices that overcome the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that provide such features by incurring as little waste as possible and do so by using the cremains as one of the major sources of fabrication material. The funerary devices and systems described herein can be manufactured to be both an object of permanence, as well as a biodegradable urn that is capable of rendering seed growth, simply by customizing the type of second material composite the ashes will be mixed with before being set by the binder, as well as the binder itself. Further, the final form of the urn is customizable through software that is able to accommodate design input as well as empirical measurement of cremain volume and iteration count to produce a unique or set of urns that are truly different for each individual. The systems, apparatuses, and methods described herein are referred to as “Oroboro.”
Provided are systems and processes for designing, fabricating, and using a funeral urn composed of the deceased's ashes, which may be called a “Radix element,” for the purpose of repurposing and/or preserving the ashes and memory of the deceased. The urn is rendered in a matrix of (1) the ashes/particulate of the deceased, (2) a second composite, and (3) a binding agent. The second composite can be either biodegradable and include seeds for plant growth if the urn is to be buried, or plastic/or metal based particulate if the urn is to be a decorative memorial implement. The binding agent may be composed of a biodegradable glue if the urn is to be buried, as well as a resin if the urn's purpose is purely decorative. The fabrication process may include 3D printing of the element into the designed form, as well as casting of the element, which would also require the 3D printed or traditional manufacture of the molds.
As a system, Oroboro seeks to solve several problems. With global mortality rates falling over the century, it is important to note that death becomes a more isolated an individualized threat in low mortality cultures. As such, history has proven that, as with Western funerary customs, practices and rituals have become extravagant, incongruous with respect to tradition or religious custom, and wasteful.
Oroboro mitigates several of the symptoms and effects of this trend. Not only are the systems, apparatuses, and methods designed to cut down on wasteful burial practices (such as the thousands of tons of embalming fluid, concrete, wood and other materials used in body preparation and gravesite and casket construction), but also to reduce the scale and cost of manufacturing of containers for remains and, inevitably, the associated material waste. Such waste includes material cut-offs, scraps, and particles. Further, Oroboro offers an alternative for diminishing available space, especially in urban and some suburban cemeteries around the U.S. Oroboro burial urns are not restricted to having to be buried in cemeteries and permanent Oroboro urns require no burial. Finally, for the biodegradable urns, Oroboro aims to resolve existential anxieties of death and impermanence by promising an alternative that can potentially result in a “life after death,” and without the environmentally destructive practices that have evolved in contemporary funeral culture. It is also important to note that some individuals may not want a biodegradable urn, but may still want to choose an alternative that is less wasteful than the current burial and urn production methods that currently exist on the market. Keepsake urns meet this need as they employ the process of Oroboro to derive an urn comprised of the cremains; however, the supplementary composite material is not biodegradable.
The inventive concepts disclosed serve a similar function to urns and other containers of funerary ashes, however, the critical difference is that Oroboro urns rely on the ash as a significant part of the manufacturing material. This characteristic mitigates the problem of excessive waste in the burial and fabrication of funerary accessories and implements. Instead of using additional material, which requires derivative manufacturing to merely hold or contain the ashes, the Oroboro process utilizes the ashes and raw unfinished particulate to fabricate the contents as the container. Additionally, the urn can be fabricated to decompose and support plant growth after burial in the ground, eliminating the need to inter the deceased or urn in the already limited space of a cemetery. This feature helps to alleviate the grief that comes with the permanence of death of a loved one, by providing the opportunity for friends and family members to “plant” their loved ones. For some customers, having a permanent memento is important, so Oroboro urns can also be made as permanent memorial sculptures, eliminating the need to inter the deceased, cutting down on the material waste of traditional urn fabrication, and still providing a memento of the deceased for friends and family to hold onto.
The fabrication process relies on two types of 3D printing to produce the customized urn, as well as traditional mold making/casting techniques. Aside from the ash particulate, there exists an opportunity to customize the overall composition of the Oroboro urn.
Customization of the urn's form is computer generated by a combination of domain specific (modeling) software and custom built software that interfaces with the output of the modeling software. The type of form customization may include, but is not limited to, overall form generation, surface ornament/treatment, photorealistic modeling or ornament/decoration, embossed or engraved text, and/or perforations for aiding decomposition of a bio urn as well as decoration. Digital customization also includes the calculation of available material and the ability to portion the cremain composite for sets of burial and/or keepsake urns. Further customization may also include the type of seeds embedded in the biodegradable urn.
In the case of fabrication of a bio urn, the second composite can include, but is not limited to, agricultural feedstock waste, clays, salts, corn byproduct, organic particulate, and other like products. Once particulate is combined, an organic binder can be applied, either to create a paste that is extruded through “Fused Deposition Modeling” or FDM 3D printing, or cast in a mold. Alternatively, the binder can be laid down by binder jetting, otherwise known as powder printing, layer-by-layer, as determined by a computer program that has sliced a 3D-computer model of the urn. The biodegradable binder may include, but is not limited to, an agent such as cornstarch or dextrin-based, flour-based, and/or corn-syrup-based glue, and/or gelatin-based, salt-based, and/or potassium-based adhesive.
In the case of fabricating a keepsake urn (i.e., a permanent device), the second composite can include, but is not limited to, clays, wood powder, plastics, metal powder, and other like inorganic composites. Once the particulate is combined, a chemical binder, such as cement can be applied prematurely for FDM-printed or cast urns. The chemical binder can also be applied after each layer of dry particulate is applied in the powder printing process.
The finishing process for both includes a glaze to protect the particulate from becoming dislodged onto any foreign body that may come into contact with the Oroboro urn. The biodegradable urn receives a glaze that is compostable and poses no harm to the surrounding soil or seeds; it may be protein based and/or hydrophilic. The keepsake urn may be finished by a number of glazes including but not limited to ceramic glaze, stains, and other chemical sealers that can be safely handled by humans once fully cured.
For biodegradable urns, the Oroboro process concludes with burial. While the urn is shelf stable for at least eighteen (18) months, it is buried no deeper than a specified depth that depends upon the type of seed chosen before fabrication, as measured from the top of the urn where embedded seed deposition exists.
With the foregoing and other objects in view, there is provided, a process for low waste production of funerary urns includes the steps of providing cremain as a powder having a particulate size of between approximately 0.1 micron and approximately 1000 microns, providing composite material as a powder having a particulate size of between approximately 0.1 micron and approximately 1000 microns, placing the cremain and composite material into an input container of a 3D printer, wherein the composite material and the cremain are mixed to have at least approximately 20% by volume of the cremain, generating a 3D printer input file corresponding to at least one urn shape, and, based upon the input 3D printer input file, printing the at least one urn shape from the mixture with the 3D printer.

Described now are exemplary embodiments. The drawings depict the flow of the fabrication and design process for the conception and production of Oroboro urns, as well as physical fabrication and makeup of the urn.
Referring now to the figures of the drawings in detail and first, particularly to
If the technician or funeral professional believes Oroboro would be an apt fit, the customer is informed of the Oroboro system and the tiered product line offerings to choose from. The customer can choose a biodegradable urn, a keepsake urn, or multiples of each kind. The number of different urn type combinations and iterations is only limited by the cremated particulate available. Once the type(s) and number of urns have been decided 110, the customer is then able to choose the shapes of the final product based on a set of pre-modeled forms, or opt to have a custom form modeled for them. These pre-modeled urns take the form of abstract geometry as well as photorealistic objects. Alternatively, the customer can opt for the production of custom models either to be 3D printed or cast from a 3D printed mold 112. Once the final model(s) have been completed and approved by the customer, the urn is ready to be fabricated. It is worth noting that steps 110 through 114 can also be completed while the deceased is living and making funeral arrangements in advance. They exist as sequential steps in
Once the customer consultation and design process is complete, the next step is physical fabrication of the urn. The exact type of composite is another parameter or attribute that the customer chooses during the consultation. Each type requires a different composite makeup that is combined with the cremains. For biodegradable urns, the added composite includes, but is not limited to, agricultural feedstock waste, clays, salts, corn byproduct, organic particulate, and other like products. The binding agent is biodegradable, such as a dextrin-based glue or chemically similar mixture. The appropriate material composition for a biodegradable binder such as dextrin-based glue is three-parts dextrin to one-part water or soluble liquid, reduced over a rolling boil for approximately an hour. For keepsake urns, the added composite includes, but is not limited to, clays, wood powder, plastics, metal powder, and other like inorganic composites 116. Binders can take the form of anything from a biodegradable binder, like dextrin glue, to a resin, collagen, casein, or wax based cement, adhesive, or binder.
To ensure high fidelity final products, the composite particulate and the cremain particulate is tumbled and ground to measure between approximately 0.1 micron and approximately 1000 microns. The variation in particle size accounts for the different types of fabrication. For powder printing, the desired particulate size range is between approximately 0.1 micron and approximately 200 microns, whereas the FDM printing and casting processes can accommodate particulate measuring along an entire spectrum of approximately 0.1 micron to approximately 1000 microns. Further, the tumbling process ensures an even distribution of ash and composite particulate in the final mixture 118.
Once the particulate has been ground to the appropriate particle size, it is ready for printing or casting. Fused Deposition Modeling is a term for Extrusion Paste Printing 120, one of the types of printing employed to fabricate Oroboro urns. The machinery necessary to extrude the paste of the ash/composite particulate and binding agent is similar to the type of setup that incorporates a RepRap 3D FDM printer and a Structur3d Printing's Discov3ry paste extruder. The process requires a hopper or plunger to load wet ash particulate and a motor to drive the material through a feed leading to a print head. Finally, the print head should be able to operate and extrude paste on three axes, regardless of whether it is modeled after a traditional 3-axis RepRap. This is only one example of how an Oroboro urn may be printed; other models include, but are not limited to, Delta printers, 5-axis robotic arms, and similar implements that could easily be retrofitted. A technician trained in operating a 3D printer or extrusion printers first mixes, for example, approximately 1 part wet binder to 3 parts particulate 122 and loads the mixture into the hopper or plunger container 124. Depending on the size of the printing system and the Oroboro urn, multiple batches of paste may be mixed and loaded throughout the duration of the printing process. It is important to note that the paste can be stored in the hopper for approximately six (6) hours and is done so without exposure to air to prevent drying or clogging. The printer extrudes paste layer-by-layer as it reads instructions written in G-code or a similar language from the program used to import a digital model of the Oroboro urn 126. For biodegradable urns, the option to incorporate seeds to facilitate plant growth requires that the final batch include the seeds in question within the paste composite mixture. Perfect even distribution of seeds within the ash and composite matrix is not necessary, however, it is important for the seeds to be distributed throughout the top 1 to 2 inches of the urn. The Oroboro urn fabrication technician makes certain that the print head is able to accommodate the extrusion of the seeds. If not, the technician may need to install a nozzle with a large enough extrusion diameter to accommodate passage of the chosen seeds. Once the urn is finished printing, it is ready to dry and set 128 for approximately twenty-four (24) hours before the final coating process.
Alternatively, the Oroboro urn can be fabricated by employing a Powder Bed, otherwise known as Inkjet Printing 130. This type of printing requires the wet binding agent to be loaded into the printer, similar to a printer like a Z Corp powder printer, separately from the chamber that holds the dry particulate, and is explained in greater detail in
Aside from directly 3D printing the Oroboro urn, it can also be cast from a mold. The mold can be fabricated using traditional subtractive modeling/mold making techniques. Casting makes the most sense as a process if the chosen form of the Oroboro urn is not complicated (complicated models feature overhangs, undercuts, or difficult to reach interstitial spaces for which casting is not suited) and is to be duplicated many times. The mold making process also incorporates 3D printing using basic plastic, sandstone, or plaster printing powder/particulate to fabricate the pattern around which the mold would be cast. A skilled mold maker is able to take a 3D printed urn pattern and cast 140 the mold surrounding. Once the mold is fabricated, it is ready to receive the wet mixture of, for example, 1-part binder to 3-parts cremain composite particulate 142. The mixture is poured through the sprue or gate, an opening in the top of the mold, and set appropriately to remove air pockets or bubbles 144. After approximately 24 hours, the mold can be removed, and the urn left to dry 146 for approximately another 24 hours. The urn is then ready for finishing during the coating process.
The finishing process is a final fabrication step before presenting the Oroboro urn to the customer. Paste extrusion printed and cast urns require a basic protective coat to prevent surface particulate from becoming dislodged onto individuals who touch the dry urn. For biodegradable urns, this coating or glaze is compostable and poses no harm to the surrounding soil or seeds; it may be protein based and/or hydrophilic. A similar type of glaze might be casein protein, or a similar paste derived from dextrin or maltodextrin. For keepsake urns, the final coating includes ceramic glaze, stains, and other chemical sealers that can be safely handled by humans once fully cured. Both types of glazes or finishes could include applied natural and synthetic coloring. Such natural dyes include, but are not limited to, vegetable dyes, animal based dyes, and other plant or fungi based dyes. Such synthetic dyes or glazed include, but are not limited to, acid dyes, basic dyes, and other inorganic chemical based dyes. Such glazes include, but are not limited to, ash glaze, tin glaze, or glazes comprising of silica, calcium, sodium, and potassium. With respect to powder printing or binder jet printed urns, the finished product is not structurally stable out of the printer and must have a resin binding agent applied as soon as possible to prevent easy breakage 148. Such coatings can be applied by brush or submersion of the urn into the binding solution. Each urn should be given approximately twenty-four (24) hours to dry after the last coat.
The urn is finally ready to be returned to the customer 150. It can stand in for an urn during a religious or end of life ceremony. Additionally, biodegradable urns are ready for planting and burial 152. They are shelf stable for minimum of eighteen (18) months, and are buried no deeper than four (4) inches below the surface of the ground to permit growth of the embedded seeds.

Should the customer choose from a set of pre-designed forms 218, the customer has the option to select photorealistic forms, such as figures related to sports, animals, or religious symbols 220. Alternatively, the customer can choose from sets of abstracted or generative forms, such as platonic solids, intersections of solids and generative motifs, as well as forms similar to that of fractals or natural phenomena 222. The Oroboro-trained designer or technician enters the appropriate information into the modeling/form generation software. This information includes the number of iterations and estimated volume of the cremain material, as well as relevant or sentimental dates or numbers that can parametrically customize the final dimensions of the form without having to manually alter the digital model 224. The final form is then ready for any final surface customization 226.
For customers choosing a custom modeled form, the process 228 differs slightly. The cost to produce custom models adds to the final price to manufacture the Oroboro urn. Photorealistic forms can be modeled after anything, from images to the deceased themselves, or forms relevant to the customer and their family 230. Conversely, more abstract forms 232 can be generated and modeled to be more sculptural or artistic in form and motif. Similarly to the process of deriving models from pre-designed forms, the customer can provide personally significant numerical values if they desire to alter or determine the final form of the custom model with the aid of the parametric design software 234, explained in further detail in
Once the final form has been modeled, the customer has the option to add embossing or engraving to the final design. Such patterns can include a name, a passage, a coat of arms, or any other graphic 238. The customer is then presented with a final rendering or visual mockup of the urn(s) that will be printed 240. When the customer signs off on the model design, the final form is then generated and exported as a supported file format (an OBJ or STL mesh format, for example) that model slicing software for printers can successfully import 242. Once imported into additional slicing software, the appropriate code is generated for the type of printer or 3D extrusion implement and exported into the correct machine readable format 244.

The Oroboro technician then chooses which process the customer has chosen from for development. If the customer has chosen to use a pre-modeled form 308, the user is directed to a visual list of models from which they may choose. Once the particular model has been chosen, the technician must enter the approximate volume of the cremain particulate, as well as the final volume of the ash and composite mixture that will be used for that particular urn edition 312. If the customer or deceased had a favorite number or wished to incorporate a numerical birth date into the urn, these numbers can be added in a custom configuration step that determines directional measurements such as height, width, length, or, for example, rotation of the model around an axis 314. This offers the customer the option to add a personal touch to the urn, despite having selected the original form from a pre-modeled list. The technician is then able to update the model with the new optional parameters and generate the final pre-made form 316.
In the event that the customer wishes to develop a custom-modeled urn 318, a technician skilled in 3D modeling begins by creating a new digital modeling workspace 320. Just as with the pre-modeled route, the technician first enters volumetric measurements based on the ash and composite particulate 322. In the custom modeling process, optional numerical parameters 324 can affect greater overall change on the final form of the model. As there is more flexibility in the design process, it is up to the customer to decide how complex and how many extra parameters they would like to manipulate. For example, a technician could create an urn out of the intersection of a sphere and a honeycomb motif. If the customer is partial to the number “16,” and the date “12-03-92,” these numbers could be entered to determine different customizable parameters, such as the diameter of the sphere (12 cm in this example), the honeycomb could have 92 hexagonal units measure the surface and measure 3 cm in diameter, while the whole structure could measure 16 cm in length. These are all arbitrary numbers that serve to illustrate how the Oroboro software facilitates overall customization of the Oroboro urn without material waste associated with custom burial implements that serve merely as containers. Finally, the model is either procedurally generated or manually modeled if the customer desired a more photorealistic design 326. The model is then ready for the final stage of customization.
Once a model has been completed, the customer has the option to add custom or pre-modeled text or graphics to be printed or cast as a raised or embossed texture 328. An example of such a graphic could include dates, bible passages, or logos of a beloved sports team. The model then undergoes a manual and automated check by printing software to ensure that there are no parts of the model that have poor structural integrity or are susceptible to breakage during and/or after printing 330. Should a flaw be found in the model of the urn, the technician edits the model until it passes inspection by the printing software, which is then exported 332 to a mesh file type, such as an .OBJ or .STL file that can be read by all common model slicing software such as Slic3r or Cura. If the technician is using external software like Slic3r, the urn model is imported into the program, where it is sliced into layers with a height that the intended printer can accommodate 334. For powder printing, the model will be sliced into layers measuring about 0.2 microns in thickness and between approximately 50 to 200 microns per layer for paste extrusion printers. Tool paths or predefined paths that the print head will travel are generated into code or a machine readable set of instructions 336. The Oroboro software consolidates this stage of the process as another step in the process of generating the urn for final fabrication. Once the instructions have been generated, they can be sent 338, e.g., through a network connection to a printer or can be transferred physically by loading the instructions onto an external storage device, such as a USB.
The concept for proprietary Oroboro software also accommodates the generation of sales estimates 340 based on the material volume and print time estimates that the software is able to generate. These are calculated by considering, for example, the speed of a respective print head, the number of layers per model, the length of each tool path, the volume of the added composite material, and the hours of technician labor tracked to generate and fabricate the Oroboro urn. The Oroboro technician is then able to generate a report or invoice 342, further consolidating an otherwise fragmented modeling and cost estimation process.
