Análise sobre a consideração da anisotropia de material e parâmetros de impressão 3D na otimização topológica de uma peça de ABS para montadora de caminhões

Abstract

The 3D printing process is becoming even more relevant in the industrial context, with its importance strengthened by the application of structural optimization. This final project aims to verify the aplicability of a proposed topology optimization procedure for 3D printed parts at the Virtual Manufacturing department at Volvo from Brazil, considering its resulting geometry and orthotropic material from the printing process. As a case study, the new procedure was used on a electrical cable spacer component printed with material extrusion technology. The finite element structural study, topological optimization and mechanical properties comparison between the current process used in the department and the proposed were made using Ansys Student version 19.2. In conclusion, it was observed that even though the simulation mechanical behaviour results are more realistic in the proposed procedure, the complexity created by the printed geometry was responsible for increasing the total procedure time in 13 times.
