Abstract: The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

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 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 a tube device having a first tube and a second tube intersected with the first tube is formed.
