Surface modification in additive manufacturing

点击翻译按钮获取中文摘要

Developing customized implants with successful bone integration is important for dental, maxillofacial, and orthopedic care in**Ontario. Liburdi has a unique direct energy deposition (DED) based additive manufacturing (AM), or 3D printing, technology that**can be further developed to efficiently produce highly customized/personalized implants on demand.**While metallic implants have become common place in dentistry and joint replacement surgeries, between 10-15% of orthopedic**and 2% of dental implants that bond to bone still fail in service within 20 years. In addition, many patients had infections from the**surgical procedures or during recovery. These problems demonstrate the need for novel surface modification processes optimized**for the additive manufacturing of metallic implant applications.**This project aims to develop new surface modification techniques that are compatible with Liburdis direct energy deposition**based AM technologies. The proposed project will focus on surface modification approaches that will 1) selectively produce**advanced surface morphology by laser machining for improved osseointegration; and 2) reduce post-surgery**infection/inflammatory response using polymer based surface modification. Integration of such technology development with**customized implant design, implant production, surgical planning, and post-surgery management will lead to a complete medical**implant solution, which will lead to a new product by Liburdi and ultimately benefit implant recipients.**.**Ontario
