Incremental Sheet Forming (ISF) technology has been mainly applied on metallic sheets during the last years. ISF is used due to its flexibility, low costs, low batch production, production of complex geometries and customized prodcuts. For this reason ISF seems to be the ideal process for prosthesis production.
The main objective of the thesis is to study the ISF technology, considering Single Point Incremental Forming (SPIF) and Two Point Incremental Forming (TPIF) variants, on biocompatible polymers to obtain a real customized cranial implant. The methodology is based on the following steps: a) Experimental work in SPIF to produce basic geometries using non-biocompatible and biocompatible polymers, b) Study of the influence of the process parameters, c) Case study: customized cranial implant. Achieving the objectives established in these stages will permit to improve the knowledge about ISF process in order to successfully manufacture customized implants at a low cost and reduced time-to-market
