A Digital Manufacture Technology for Skull Prosthesis Using Incremental Sheet Forming Method

Abstract:

In order to alleviate the suffering of the patients with skull defects, this paper presents a detailed analysis of incremental sheet forming (ISF) method to shape skull prosthesis of titanium alloy meshed plate. In the study, we emphasized the following points: First, we designed and made skull model based on computed tomography image, and extracted the skull defect data using reverse engineering technology, then we reconstructed the surface of the prosthesis and designed it’s three dimentional model, finally, we adjusted tool path repeatedly and then imported the tool path into incremental sheet forming system to shape skull prosthesis. This paper provides a fast and accurate prosthesis manufacture method of titanium alloy meshed plate, which can improve the level of the skull repair technique.
