Development of Characterization Controls for 3D-Printed Implants by Direct Energy Deposition

Currently, the largest market share of biomedical implants consists of devices fabricated from metallic materials such as titanium,**and cobalt-chromium alloys using conventional casting processes. While the implantation of these metallic biomaterials has**become common place in dentistry, oral maxillofacial, and joint replacement surgeries, between 10-15% of orthopaedic and 2% of**dental implants still fail in service. The lack of patient specific devices with both appropriate mechanical, materials and biological**properties is one of the causes for this failure. With instruments now capable of printing metals, additive manufacturing, or 3Dprinting,**is a promising technology for manufacturing customized medical implant devices that can be optimized for better success.**However, there remains several challenges related to the materials optimization during additive manufacturing to meet the**stringent materials and mechanical properties for medical implant regulations. A thorough and robust high-resolution materials**characterization and understanding of local mechanical properties will help to advance biomedical implants produced by additive**manufacturing. Liburdi Engineering is interested in developing their manufacturing instrumentation for applications in additive**manufacturing of biomedical implants, since their current direct energy deposition technology has several advantages to**conventional powder-bed additive manufacturing. By partnering with McMaster University, this project will provide significant**advancements in developing the 3D-printing technology by understanding and optimizing the materials produced.**.**Ontario
