Abstract:
Powder bed fusion systems, apparatus, and processes for the production of multi-material parts are provided, in which the material composition varies throughout the part, including different regions within a particular layer. Present embodiments include the capability to selectively deliver fusion-inducing energy over the part bed as each layer of the part is made, rather than uniformly over the part bed, and include those wherein a digital light processing (DLP) projector interfaces with the thermal source to direct the application of energy from the thermal source.
