Biocompatible 3D printing resins for medical applications: A review of marketed intended use, biocompatibility certification, and post-processing guidance

Over the last thirty years, there has been an increase in the adoption of 3D printing by the medical community to create devices for patients that require custom and rapid solutions. In turn, a demand has been created for a variety of specifically engineered biocompatible materials. The aim of this study was to review the information provided with biocompatible photosensitive resins with regards to their intended uses, cited biocompatibility certifications, and post-processing technique, and arising from this, detail challenges for users when making an informed and safe decision regarding material selection.
