Research Progress of Bone Implant Additive Manufacturing

Abstract

Bone implants are currently a solution for the treatment of large bone defects. The structural design and manufacture of complex bone tissue engineering scaffolds can be realized by using additive manufacturing technology. Advances in additive manufacturing techniques and the continued emergence of related materials provide different opportunities for new bone implant techniques to achieve the challenging requirements of proposed bone implants. The purpose of this review is to present the current status and analyze the advantages and disadvantages of various additive manufacturing for the manufacturing of bone implants. Five different manufacturing techniques (multilayer deposition forming, ink direct writing, laser melting, laser sintering, and light curing are reviewed.) and the currently required bone implants technology, and thus put forward the research and development direction of additive manufacturing suitable for bone implants.
