Research in PORTUGUÊS

This paper aims to describe the process of digital manufacturing of facial prostheses for patients injured by cancer. For this the proposed innovation is the use of low-cost digital tools, such as photogrammetry, 3D modeling and 3D printing. The main software used are: Blender for modeling the prostheses and the add-on OrtogOnBlender for generating photogrammetry. As a result of the process, the following can be observed: 1 - Less invasive approach to the patient; 2 - Low production cost; 3 - Optimization in production time; 4 - Greater anatomy accuracy and prosthesis details; 5 - Documentation through digital recording of the entire process.
