摘要： A High Energy Beam Processing (HEBP) system (1) provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Signals (301, 302, 303, 308) reflecting process parameters and the quality of the fabricated parts are analyzed by monitoring feedback signals from artifact sources (61A, 61B, 62A, 62B, 63A, 63B, 64A, 64B) with a process controller (20) which adjusts process parameters. In this manner, fabricated parts are produced more accurately and consistently from powder feedstock by compensating for process variation in response to feedback signals.

摘要： A component is fabricated in an additive manufacturing process. Only a portion of a first layer of a first material is at least partially melted to define a first component layer of the component. Only a portion of the second layer of a second material is at least partially melted to define a second component layer of the component in which the entirety of the second component layer is formed simultaneously, and the second component layer is attached to the first component layer. b6 d1 as - q

摘要： An implant is produced by fabricating first and second layers. The first layer of repeated and truncated building units is fused together to define pores. The second layer of repeated and truncated building units are fused together to define pores and fused onto the first layer of truncated building units. The first and the second layers form at least part of a porous portion of the implant. The formed porous portion is attached onto a base portion of an implant. The truncated building units of each of the first and the second layers are in the form of spatially overlapping three-dimensional shapes. [FIG. IC for publication] FIG.l A FIG.l B

摘要： A bone part is repaired by a process. A first implant is attached to a first bone part. The first implant corresponds to an intraoperatively defined or an intraoperatively selected cutting path. A preoperatively defined second implant is attached to the first implant. The first implant and the second implant together augment the first bone part.

摘要： A porous apparatus 210 including a first layer 220 and a second layer 230 is disclosed. The second layer has a plurality of struts 240. At least some of the struts 240 define a porous geometry defining a plurality of faces 285, and at least one of the faces 295 partially confronts the first layer. Each face is bounded by intersecting struts at vertices. Some of the vertices of each face 295 of the porous geometry confronting the first layer 220 are connected by a strut 240 to the first layer 220. A process of producing the at least partially porous structure includes depositing and scanning metal powder layers. At least some of the scanned metal powder layers form either one or both of a first section of the structure and a portion of a second section of the structure formed by at least the struts defining the porous geometry.
