Abstract
A medical implant which comprises a porous lattice is fabricated with additive manufacturing techniques such as direct metal laser sintering. A CAD model of the porous lattice is created by defining a trimming volume and merging some lattice elements with adjacent solid substrate.
Claims15
A method of fabricating an implant device comprising a porous lattice, the method comprising:
- creating, by a computing device, a model of the implant device comprising the porous lattice, the creating comprising:
- defining an initial lattice volume having a bounding surface for the implant device,
- populating the initial lattice volume with a plurality of seed points,
- populating the initial lattice volume with a plurality of nodes and struts that connect the nodes to divide the initial lattice volume into a plurality of 3-dimensional regions, thereby defining an initial lattice,
- attracting one or more nodes and/or struts toward a substrate of the implant device such that at least one attracted node or strut is positioned coincident with or at least partly within the substrate of the implant device, and
- merging some or all of the attracted nodes and/or struts with the substrate of the implant device.
- fabricating the implant device comprising the porous lattice at least in part by exposing fusible material to a heating source according to the model.
