Additive Manufacturing – Applications and Sustainability
We are investigating surface finishing of additively manufactured implants for veterinary medicine. Abrasive finishing reduces the surface roughness effectively, but studies in the literature are not comprehensively described [Fashanu20]. Grindability of extruded and 3D printed PEEK samples was studied to improve post-processing repeatability and automation [Linke24a]. This is collaborative research with Prof. Denis Marcellin-Little, Surgical & Radiological Sciences, School of Veterinary Medicine, UC Davis.
Polymer 3D printing can generate physical 3D models of organs to help with training and research studies [Roeth19],[Roeth21]. Its sustainability can be improved by considering printing energy, part dimensions, surface roughness, material recyclability, and waste [Linke23]. This research is performed with Dr. med. Dipl.-Phys. Anjali A. Roeth, ESCAM – European Surgical Center Aachen Maastricht, The Netherlands, University Hospital RWTH Aachen, Germany.
A study with Prof. Erick Ramírez-Cedillo (Tecnológico de Monterrey, Mexico) and Prof. Mohsen Habibi (UC Davis) studies the design of mobile, energy-efficient, and sustainable 3D printing systems that can be used in emergencies and in rural communities to print essential medical and mechanical parts [Linke24b].
Further studies at the Master Lab have looked into environmental impacts and perceived quality of polymer 3D printing [Li17] and energy use during fused deposition modeling [Wang21]. RPTU Kaiserslautern led a Unit Process Life Cycle Inventory on high speed laser directed energy deposition [Ehmsen23].
