Projeto de protótipo de extrusora para produção de filamento de impressora 3D

Abstract

This work presents a theoretical and constructional approach of an extruder machine used for the production of 3D printing filament, as well as the plastic behaviour ABS applied to the process. Based upon the technical information available on the literature and through the benchmarking, a desktop extruder prototype was designed, built and tested. The extruder alone is not able to maintain the diameter size constant in process, which requires the development of auxiliary measurement and control systems, that can be develop in future works. Although it is possible to manufacture an extruder with components, which are found in the market, reducing time and manufacture costs, in order to foster the 3D printing.
