A digital workflow to produce maxillofacial prostheses could improve reproducibility and aesthetic outcomes. The possibility to 3D scan patients’ limbs is given, but there is no method established to produce the prostheses from this data. In this study, tests were performed and a protocol developed to print 3D objects from water-soluble polyvinyl alcohol (PVA) in consistent quality. Prototypes of maxillofacial prosthesis were fabricated (Figure 1). Those could be used to create molds for the casting...
