Abstract
Systems and methods for fabrication of implantable medical devices using an Electron Beam Melting (EBM) manufacturing process are provided. According to one embodiment, an EBM manufacturing system is caused to perform a fabrication process that results in an implantable medical device of unitary construction having a solid volume and a porous volume. A layer of metal powder is spread across a build platform of the EBM manufacturing system. Portions of the layer of metal powder are selectively heated in accordance each portion's association with the solid volume or the porous volume by scanning the layer of metal powder with an electron beam of the EBM manufacturing system and adjusting a power of the electron beam and a speed of said scanning. The build platform is lowered based on a predetermined layer thickness and the process of continues on a layer-by-layer basis until the implantable medical device is completed.
