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.

Surface modified unit cell lattice structures for optimized secure freeform fabrication

A High Energy Beam Processing (HEBP) system provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Signals reflecting process parameters and the quality of the fabricated parts are analyzed by monitoring feedback signals from artifact sources with a process controller 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.

Device for in-situ fabrication process monitoring and feedback control of an electron beam additive manufacturing process

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.

Fabrication of components using shaped energy beam profiles

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.

High fatigue strength porous structure

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.

The present invention relates to a dental implant and to a process for fabricating the dental implant.

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 predefined portion of a boundary. A space including the porous CAD volume is populated with unit cells overlapping the predefined portion of the boundary. The unit cells are populated with porous geometries having a plurality of struts having nodes on each end. At least a first strut overlaps the predefined portion of the boundary and has a length, a first node outside the porous CAD volume, and a second node inside the porous CAD volume. All struts entirely outside the porous CAD volume are removed. After removal of the struts entirely outside the porous CAD volume, each of the remaining struts is connected to a node at each end thereof.
