Abstract: Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer may be fabricated between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering. Interface layers suitable for manufacture with an additive manufacturing system may resist the formation of bonds between a support structure and an object during subsequent sintering processes.

Abstract: Systems, methods, components, and materials are disclosed for stereolithographic fabrication of three-dimensional, dense objects. A resin including a first binder, a second binder, and dispersed particles can be exposed an activation light source to cure at least one of the binders in a layer-by-layer process to form a green object including the first binder, the second binder, and the particles. A dense object, such as a metal object, a ceramic object, or a combination thereof, can be formed from the green object by thermally processing the particles and removing the first binder through a primary debinding process, removing the second binder through a secondary debinding process different from the primary debinding process.

Abstract: A three-dimensional printer uses a fused filament fabrication process to fabricate a net shape object from build materials that can be debound and sintered into a final part. In order to facilitate separation of the object from surrounding support structures, the three-dimensional printer is configured to deposit material between adjacent surfaces of the object and the support that inhibit bonding between adjacent surfaces of the support structure and the object during sintering.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a build material. One or more energy directors such as ridges are formed in an exposed surface of the deposited build material to provide regions of high, localized contact force that can improve interlayer bonding between successive layers of the build material. An ultrasonic vibrator can also usefully be incorporated into the printer to apply additional energy along these energy directors during deposition of a subsequent layer.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process. The exit of the nozzle may include a number of concentric rings, where each of which may be selectively opened or closed during extrusion to control extrusion properties such as a volume of extrudate or a mixture of material exiting the nozzle.

Abstract: Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is formed between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering. The support structure may be a multi-part support structure to mitigate mold lock or facilitate removal from enclosed spaces.
