Design and fabrication of an open-source 4-axis milling machine for dental prosthesis production

Abstract

This article will present the development of a low-cost CNC milling machine for manufacturing dental prostheses. In this study it was proposed the development of a CNC milling machine using parts made on a 3D printer, through the study of various printing parameters to deliver resistant and durable parts, reducing their final production cost. The implementation of the CAD-CAM flow in dentistry brings precision and increased production to laboratories and clinics, thus delivering prostheses with greater quality and durability. Unfortunately, the high cost still impacts its implementation and part of the population that requires prostheses is unable to obtain the benefit of good restorations, both aesthetically and functionally. With this research, engineers and technicians can built their own machine and focus on improvements, reduction of development costs and teaching in the areas of mechatronic and dental engineering. Also, with this research it is possible to inspire the dissemination of knowledge of milling technology applied to the manufacture of high-precision prostheses. Over time, this technology could be more accessible to dental laboratories and clinics, people will receive more dental prosthetics made with the benefits of CAD-CAM technology. The results of this study shows that it is feasible to develop this technology with low production costs and open-source, making it accessible to the community.
