Porous implant structures

A method for fabricating a porous structure, said method comprising the steps of:

• creating a computer aided design (CAD) model of the porous structure;
• the creating comprising:
• determining a shape and size of a frame for one or more cells of the porous structure, where the shape of the frame comprises a geometric shape selected from the group consisting of Archimedean shapes, Platonic shapes, strictly convex polyhedrons, prisms, anti-prisms and combinations thereof;
• defining the frame based on the shape and size determined;
• defining two or more struts with a first end, a second end, and a continuous elongated body having a length between the first and second ends for each strut, wherein said body comprises a curved portion, the curved portion curves along at least a portion of the length between the first and second ends;
• defining at least one junction with a tangential intersection between two of said curved portions;
• and
• adding the two or more struts and the at least one junction to the frame;
• selecting a thickness for the frame and the one or more struts;
• and
• fabricating the porous structure according to the CAD model by exposing fusible material to an energy source.
