Aylvin Dias, PhD, DSM, Geleen, The Netherlands, provides an overview of the development process for personalized 3D printed wrist implants. Various technologies such as injection molding were explored and were found to be superior to 3D printing, due to 3D printed models not having the required properties required for implants. Safety was an additional concern, with materials used in injection molding having a more established safety profile. Dr Dias also discusses the regulatory process for approving personalized medical devices, and innovations in the field. This interview took place at the 6th World Congress of the Tissue Engineering and Regenerative Medicine International Society (TERMIS 2021).
