摘要： Systems, methods, components, and materials are disclosed for stereolithographic fabrication of three-dimensional, dense objects. A resin including at least one component of a binder system and dispersed particles can be exposed to an activation light source. The activation light source can cure the at least one component of the binder system to form a green object, which can include the at least one component of the binder system and the particles. A dense object can be formed from the green object by removing the at least one component of the binder system in an extraction process and thermally processing particles to coalesce into the dense object.

摘要： The devices, systems, and methods of the present disclosure are directed to powder spreading and binder distribution techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, a powder may be spread to form a layer along a volume defined by a powder box, a binder may be deposited along the layer to form a layer of a three-dimensional object, and the direction of spreading the layer and depositing the binder may be in a first direction and in a second direction, different from the first direction, thus facilitating rapid formation of the three-dimensional object with each passage of the print carriage over the volume. Powder delivery, powder spreading, thermal energy delivery, and combinations thereof, may facilitate consistently achieving quality standards as the rate of fabrication of the three-dimensional object is increased.

摘要： A variety of additive manufacturing techniques can be adapted to fabricate a substantially net shape object from a computerized model using materials that can be debound and sintered into a fully dense metallic part or the like. However, during sintering, the net shape will shrink as binder escapes and the base material fuses into a dense final part. If the foundation beneath the object does not shrink in a corresponding fashion, the resulting stresses throughout the object can lead to fracturing, warping, or other physical damage to the object resulting in a failed fabrication. To address this issue, a variety of techniques are disclosed for substrates and build plates that contract in a manner complementary to the object during debinding and sintering.

摘要： Systems, methods, and components are disclosed for controlling layer separation in stereolithographic fabrication of three-dimensional objects. Each layer of the three-dimensional object can be cured and separated in discrete portions to facilitate controlling forces in the layers of a three-dimensional object. For example, controlling curing and separation of layers of a three-dimensional object according to the systems, methods, and components disclosed can facilitate accurately forming the three-dimensional object from cured particle-loaded resins. More specifically, particle loading can decrease the shear strength of the cured resin and, thus, controlling the forces exerted on a given layer of a cured particle-loaded resin can be particularly useful for reducing the likelihood of deformation in a three-dimensional object including the particles. In turn, the accurately formed three-dimensional object including the particles can be densified to form a dimensionally accurate finished part.

摘要： 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.

摘要： A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. A build plate that receives the object during fabrication includes a coating of material with a low melt temperature, such as a low melt temperature solder. In particular, the material may be an alloy that can be solidified while receiving the object, and then heated into a liquid state to facilitate removal of the object after fabrication is complete at a temperature sufficiently low that the adjacent, fabricated object does not melt or deform.

摘要： A printer fabricates an object from a build material based on a computerized model and a fused filament fabrication process. A nozzle for depositing the build material has an interior diameter approaching an outer diameter of build material fed to the nozzle in order to reduce extrusion and resistance forces imposed by the nozzle during deposition, while adequately constraining a planar position of the build material for accurate material deposition in a computer-controlled fabrication process.
