摘要： 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.

摘要： Method of providing a desired material on at least a portion of a surface of a substrate of a component, such as a medical implant component. The method may comprise the steps of arranging the component in a holding fixture which is capable of holding the component at atmospheric or substantially atmospheric pressure, and spraying particles of the desired material at a predetermined high velocity toward the at least one portion of the surface of the substrate so as to enable a layer of the material to be accumulated thereon. The spraying may be performed at atmospheric or substantially atmospheric pressure. The desired material may be a reactive type material, such as titanium or an alloy thereof. The method may enable a high density coating or layer of the material to be provided without the use of a post spray thermal consolidation process.
