Abstract:
1. A method of preparing a computer-generated model of a three-dimensional structure constructed of porous geometries, the method comprising: preparing a computer-generated component file including a porous CAD volume having a boundary; populating, by a processor, a space including the porous CAD volume with unit cells, at least one unit cell overlapping the boundary; populating, by a processor, the unit cells with porous geometries, a plurality of the porous geometries having a plurality of struts having opposing ends, each end being connected at a corresponding node, at least one strut overlapping the boundary and having a length, a first node outside the porous CAD volume, and a second node inside the porous CAD volume; removing, by a processor, all struts entirely outside the porous CAD volume such that each end of the remaining struts remains connected at its corresponding node; and populating, by a processor, the space with at least one elongated fixation element extending beyond the boundary to produce an interlocking feature to enable assembly or engagement with a mating structure.
