Abstract: The present invention is directed to a medical implant, methods of use and making of such implants. A method of making an implantable device may include obtaining an anatomical model in a computer aided design (CAD) system, customizing the anatomical model per patient specific parameters and creating a virtual image of the anatomical model, incorporating at least one microchannel geometry within said anatomical model, adjusting the density infill to a measurement ranging per patient specific parameters, and using three-dimensional printing to form the implantable device based on the anatomical model. The implant can be made of suitable metallic or polymeric material, such as PLA.
