Food products are produced in a layer-by-layer manner without object-specific tooling or human intervention. Color, flavor, texture and/or other characteristics may be independently modulated throughout the food product. In addition, in some cases, the food products may further undergo one or more post-processing steps.

Abstract: There is provided compositions and methods for producing three-dimensional objects by selective deposition modeling with a polar build material and a non-polar support material. The build material comprises a hydrocarbon wax material and a viscosity modifier, and the support material comprises a hydrocarbon alcohol wax material and a viscosity modifier. After the selective deposition modeling process has been completed, the object can be placed in a bath of polar solvent to remove the support material. The particular materials provided herein, and the post-processing methods associated therewith, provide for improved part quality of the three-dimensional object and for improved post-processing techniques. The three-dimensional objects can subsequently be used in a number of applications, such as patterns for investment casting.

Abstract: There is provided a support structure for use with 3D printing of objects from computer-aided designs. The support structures include fine points that contact the down-facing surfaces of the 3D object being printed in order to adequately support the 3D object while also being adapted for easy removal after the 3D print process is complete. The fine points are possible by controlling the operation of the dispenser to provide a precise amount of material in a precise location. The dispenser jumps from a first fine point to a second fine point by retracting the print material after the first fine point is printed and then moving the dispenser vertically relative to the first fine point before the dispenser is moved horizontally to the second fine point.

Abstract: There is provided solid imaging methods and apparatus for making three-dimensional objects from solid imaging material. A tray with a film bottom is provided to hold solid imaging material that is selectively cured into cross-sections of the three-dimensional object being built. A coater bar is moved back and forth over the film to remove any uncured solid imaging material from a previous layer and to apply a new layer of solid imaging material. A sensor is provided to measure the amount of resin in the tray to determine the appropriate amount of solid imaging material to be added, from a cartridge, for the next layer. A shuttle, which covers the tray when the exterior door to the solid imaging apparatus is opened for setting up a build or removing a three-dimensional object, can also be used to move the coater bar and to selectively open one or more valves on the cartridge to dispense the desired amount of solid imaging material.

Abstract: A method of fabricating an article, such as a prototype part or a tooling for injection molding, by way of selective laser sintering, using a composite powder system of a metal and/or ceramic powder with a polymer binder comprising thermoplastics and thermoset polymers, and a metal hydride powder to form a nullgreennull article. After removal of unfused material from the green article it is placed in an oven or furnace in a non-reactive atmosphere such as, for example, nitrogen or argon, for subsequent heat treatment to decompose and drive off the binder and sinter the metal substrate particles prior to infiltration by a metal with a lower melting point. During the critical step of decomposing the binders, the metal hydride begins to decompose also and releases an in-situ concentration of hydrogen gas that creates the reducing conditions necessary to thoroughly decompose the polymer fragments so that the hydrocarbon fragments can escape the skeleton structure of the article. It has been found that even with higher loadings of binders, leading to higher desired green strengths, the decomposition of the metal hydride eliminates the blistering phenomena associated with high loadings of some binders.

Abstract: In solid freeform fabrication processes that make use of a removable support material, pre-calculation of the amount of support material needed for a build is difficult (inaccurate or slow) because the digital data for generating the support material is often not generated until the build is in progress. A method is proposed that has been shown to generate rapid and accurate estimates of the amount of both build and support material needed before a build begins, to accurately predict before a build begins when replenishment materials are needed, and to track material consumptions over time.

Abstract: A computer-controlled apparatus and method for fabricating three-dimensional articles in layerwise fashion is disclosed. Upon dispensing a layer of a fusible powder, a laser irradiates selected locations of that layer to fuse the powder into a cross-section of the article to be formed in that layer, such that the fused cross-sections fuse together into the article. The laser is controlled in a raster scan fashion across the selected locations of the powder layer. The parallel raster scan lines are separated from one another, centerline-to-centerline, according to a selected pitch, or fill scan spacing value. The positions of the parallel scan lines are determined with respect to a coordinate system at the powder layer, rather than with respect to boundaries of the cross-section being formed; in alternating layers, the parallel scan lines are offset from one another by one-half the pitch. This arrangement of the scan lines optimizes the structural strength of the article being formed, while minimizing the number of scans required to form the article.
