摘要： A 3D printing system and methods to selectively pattern dense feedstock based on selective inhibition sintering (SIS). A sintering selectivity agent (inhibitor or promoter) is selectively deposited on a build layer according to the pattern boundary. When the layers are built-up and the part is sintered, the inhibited region remains unbound, thus defining the edge of the part. The material contain powder embedded in cohesive binder that make the adjacent layer adhere together. The build process involves forming the sheets of dense feedstock embedded binder, followed by depositing ink to promote selective sintering onto the layer. Once the build is complete, the process continues with the binder removal, sintering and finishing processes.

摘要： A deployable manufacturing center (DMC) system includes a foundry module containing a metallurgical system configured to convert a raw material into an alloy powder, and an additive manufacturing (AM) module containing an additive manufacturing system configured to form the alloy powder into metal parts. The deployable manufacturing center (DMC) system can also include a machining module containing a machining system configured to machine the metal parts into machined metal parts, and a quality conformance (QC) module containing an inspection and evaluation system configured to inspect and evaluate the metal parts. A process for manufacturing metal parts includes the steps of providing the deployable manufacturing center (DMC) system; deploying the (DMC) system to a desired location; forming an alloy powder from a raw material using the deployable foundry module; and then forming the metal parts from the alloy powder using the additive manufacturing (AM) module.

摘要： Modular additive manufacturing systems, related methods for simultaneously building three-dimensional parts in successively bonded layers, and related computer readable storage medium. A plurality of build assemblies is laid out along at least one direction of a manufacturing path defining a loop, and at least one build assembly is functioning to build a three-dimensional part from build material according to build instructions. A guidable module is guided via a guiding assembly along the manufacturing path to repeatedly perform at least one step necessary to build the three-dimensional part on each functioning build assembly.
