Background: Additive manufacturing (AM) have become increasingly important in personalized medicine. To finally introduce AM to the clinic, preclinical investigations are necessary to guarantee patients’ safety. 3D-printed parts must be free of pathogens and contaminants, but reliably maintain their mechanical properties. PMMA (Polymethylmethacrylate) has already been used for years for...

Various plastics have a long tradition and have been successfully established as biomaterials for implants.
