Three dimensional (3D) printing is a technology that is rapidly developing and being integrated into manufacturing of different parts and prototypes for a variety of industries. Many people have heard of the emergence of 3D Printing into the commercial world but labeled by different names such as additive manufacturing (AM), rapid prototyping (RP), layered manufacturing (LM) or solid freeform fabrication (SFF). Conceptually, 3D Printing or AM is an approach where 3D designs can be built directly from a computer aided design file without any part specific tools or dies. In this freeform layer-wise fabrication, multiple layers are built in the X-Y direction one on top of the other generating the Z or 3rd dimension. Once the part is built it can be used for touch and feel for concept models, tested for functional prototypes, or used in practice. Over the years, we have used 3D Printing to manufacture patient specific implants, implants with tailored porosity to enhance osseointegration or bone bonding, and implants with better articulation surface to reduce metal ion release. My presentation will focus on application of laser based 3D printing or additive manufacturing in biomaterials with special emphasis on biomedical devices.
