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.

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.

Abstract: A method is provided for depositing a hard wear resistant surface onto a porous or non-porous base material of a medical implant. The wear resistant surface of the medical implant device may be formed by a Laser Based Metal Deposition (LBMD) method such as Laser Engineered Net Shaping (LENS). The wear resistant surface may include a blend of multiple different biocompatible materials. Further, functionally graded layers of biocompatible materials may be used to form the wear resistant surface. Usage of a porous material for the base may promote bone ingrowth to allow the implant to fuse strongly with the bone of a host patient. The hard wear resistant surface provides device longevity, particularly when applied to bearing surfaces such as artificial joint bearing surfaces or a dental implant bearing surfaces. An antimicrobial material such as silver may be deposited in combination with a metal to form an antimicrobial surface deposit.

Abstract: The invention relates to ZrB.sub.2 /Cu composites, and more specifically to methods of making ZrB.sub.2 /Cu composite electrodes and methods of using ZrB.sub.2 /Cu composite electrodes. ZrB.sub.2 powder is contacted with a polymer and shaped to a desired form. The polymer is vaporized and the ZrB/.sub.2 powder is sintered. The sintered ZrB.sub.2 is contacted with Cu and heated above the melting point of Cu which causes the Cu to infiltrate the ZrB.sub.2, forming the ZrB.sub.2 /Cu composite electrode.
