Manufacturing of Polymeric Biocompatible Cranial Geometry by Single Point Incremental Forming

Abstract Incremental Sheet Forming (ISF) technology is used to manufacture customized products and its application to metallic prosthesis manufacturing has been already tested. However, the use of thermoplastic sheets as raw material in ISF is still reduced and therefore the manufacturing of polymer prosthesis by this technology too. In this framework, the objective of the present paper is to obtain a real cranial geometry of a feasible prosthesis manufactured by ISF using a biocompatible polymer. The real geometry of a cranial fracture is acquired from a computer tomography and treated until get a CAD model. From it, the trajectories have been defined and the cranial geometry manufactured.
