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: 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: A high energy beam verification, calibration, and profiling system includes a conductive base plate, supports extending from the base plate, a plurality of conductors, a data logger electrically connected to the conductors, and a computer electrically connected to the data logger. Each conductor is supported by some of the supports such that each conductor is insulated from the conductive base plate. Each conductor has a profile intersecting with profiles of at least some of the other conductors to define a multidirectional and two-dimensional array of conductors. The data logger receives and records data associated with electrical charges flowing through the conductors. The computer is adapted to receive, manipulate, and display the data recorded by the data logger for comparison of beam characteristics at different locations across a high energy beam build area.

Abstract: A method of forming a tubular structure including a first tube and a second tube. The steps of the method include first successively depositing layers of a first material and at least partially melting at least a portion of each deposited layer of the first material at predetermined locations to form the first tube. Second, successively depositing layers of a second material and at least partially melting at least a portion of each deposited layer of the second material at additional predetermined locations to form the second tube, wherein the second tube is attached to the first tube at an intersection. Additionally, at least partially melting steps include forming portions of a plurality of segments, and the first tube and the second tube share segments of the plurality of segments at their intersection.

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.
