Abstract: Aspects of the present disclosure relate generally to preparing models of three-dimensional structures. In particular, a model of a three-dimensional structure constructed of porous geometries is prepared. A component file including a porous CAD volume having a boundary is prepared. A space including the porous CAD volume is populated with unit cells. The unit cells are populated with porous geometries having a plurality of struts having nodes on each end. The space is populated with at least one elongated fixation element extending beyond the boundary to produce an interlocking feature enabling assembly or engagement with a mating structure.

Abstract: 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.

Abstract: A packaging system includes a packaging unit and an article. The packaging unit includes a solid layer, a porous layer and a plastic layer with a cavity. The cavity is configured to receive and secure the article in an opening defined by the cavity that is flexible between a first and a second dimension. The packaging unit is fabricated by a 3D printing process. A tensioning device of a 3D printing machine tensions a feed filament during the 3D printing process.

Abstract: A three-dimensional structure is formed when layers of a material are deposited onto a substrate and scanned with a high energy beam to at least partially melt each layer of the material. Upon scanning the layers at predetermined locations at least a first segment overlapping a second segment and underlapping a third segment is formed.

Abstract: A porous apparatus includes a first layer and a second layer. The second layer has a plurality of struts. At least some of the struts define a porous geometry defining a plurality of faces, at least one of the plurality of the faces at least partially confronting the first layer. Each face is bounded by intersecting struts at vertices. Less than all of the vertices of each face of the porous geometry at least partially confronting the first layer are connected by a strut to the first layer. 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 portion 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.
