Resumen
A manufatura aditiva está em evolução, sendo a Fabricação por Filamento Fundido uma das tecnologias mais populares. A oferta de filamentos de novos materiais poliméricos tem crescido, inclusive de polímeros de alto desempenho. Existe uma ampla gama de aplicações destes materiais, porém são difíceis de processar em impressoras 3D comuns. Para viabilizar pesquisas com estes materiais, foi desenvolvido um protótipo de impressora com cinemática delta invertida. Na validação do equipamento, foram identificadas ondulações e variações dimensionais excessivas nas peças impressas. O objetivo deste trabalho foi desenvolver uma nova plataforma de construção e aperfeiçoar os módulos de movimentação lineares. Após as melhorias realizadas a plataforma conseguiu atingir temperaturas adequadas e usando filamento de ABS, a repetitividade nas peças impressas foi aprimorada de ± 0,27 mm para ± 0,09 mm. Esses avanços são importantes para continuar o desenvolvimento da máquina e possibilitar novos estudos com polímeros de alto desempenho.
Additive manufacturing is evolving, with Fused Filament Fabrication being one of the most popular technologies. The supply of filaments made from new polymeric materials has been growing, including high-performance polymers. There is a wide range of applications for these materials; however, they are difficult to process with common 3D printers. To enable research with these materials, a prototype printer with inverted delta kinematics was developed. During the validation of the equipment, excessive ripples and dimensional variations were identified in the printed parts. The objective of this work was to develop a new build platform and improve the linear motion modules. After the improvements were made, the platform managed to reach adequate temperatures, and using ABS filament, the repeatability of the printed parts was enhanced from ± 0.27 mm to ± 0.09 mm. These advancements are important for continuing the development of the machine and enabling new studies with highperformance polymers.
