Overview
Low-cost fabrication methodology for palatal obturator prostheses is a research collaboration between +Lab, Politecnico di Milano, and the Dental School, Vita-Salute San Raffaele University. The project explored the use of low-cost Fused Filament Fabrication (FFF) 3D printing and indirect fabrication techniques to produce patient-specific palatal obturator prostheses (maxillofacial devices used to restore function following palate resection) starting from DICOM medical imaging files. The methodology combines parametric design, indirect 3D printing, and silicone casting to generate customized prostheses in cases where conventional acquisition methods or fabrication cannot be used, for instance, for patients with limited oral cavity opening. 1

My contribution:
- Methodology development: Developed the fabrication methodology combining parametric design, mesh sculpting, indirect 3D printing, and silicone casting for the production of patient-specific palatal obturator prostheses from DICOM files.
- Product design: Design of the palatal obturator and its corresponding mold starting from the DICOM file and considering the fabrication method (silicone casting in FFF 3D-printed molds), reducing material use and improving adaptation for reduced oral mobility.
- Additive manufacturing: Designed and fabricated prosthesis prototypes and casting molds using low-cost Fused Filament Fabrication (FFF) 3D printing; managed silicone casting for the final prosthesis, including maxillofacial-grade silicone.
- Thesis co-supervision: Co-supervised one MSc thesis focused on the preliminary study of the case and validation of the clinical workflow at Vita-Salute San Raffaele University in collaboration with +LAB.
