Implant fusion device and method of manufacturing

A method of making a spinal implant device or orthopedic device or bone implant device comprises the steps of:

• fabricating an implant body structure using 3D printing to create the implant body structure;
• additively building the body structure having a superior load bearing surface and an inferior load bearing surface and a wall structure;
• and
• wherein the body structure has at least a portion of the body structure having a plurality of interconnected struts forming porous walls with openings extending inwardly from an exterior surface to a depth of 1.0 mm or greater forming a porous portion with a void volume to solid mass volume mimicking trabecular bone.

• and
• laser etching nano channels on at least a portion of the exterior surface or surfaces of the implant body structure, the nano channels creating new bone growth attachment features to enhance osteoinductivity of the spinal implant fusion device.
