摘要：
A spinal interbody implant is fabricated using 3-D printing to provide an engineered structure of one or more porous, permeable, or non-solid portions with or without one or more solid, dense, or micro-dense portions. The porous, permeable, or non-solid structure can be a mesh, lattice, web, weave, honeycomb, simple cubic, tetrahedral, diamond, or otherwise with the number and size of its pores, holes, perforations, or openings, as well as the distance or thickness between them, can vary accordingly. Some portions of the porous, permeable, or non-solid structure(s) may have porosities and/or thicknesses different than other portions. The solid, dense, or micro-dense structure may be constant throughout the body of the implant or may be a range of densities throughout the body of the implant. Alternately, one or more portions of the implant may have a range of densities throughout its body ranging from solid to a maximum porosity.
