Aplicação do método de Taguchi na otimização das propriedades mecânicas em protótipos 3D – manufatura aditiva

Abstract

The study proposes a simple and effective processes in the quality improving of mechanical materials properties. The procedures are divided into seven steps: material setting, equipamento setting, variables setting, modeling, material testing. calculations survey and optimal parameters setting. Manufacturing structural factors were chosen and classified into three parameters and levels. The Taguchi method in this stage will allow a test systematization, test time reduction and mechanical properties optimization. The importance of additive manufacturing and PLA polymer will be as well discussed. The presente study aims to define specimen's maximum tensile and elongation, based on types of mesh, layer height and mesh angle, thus, defining it as a better configuration for higher response values. The study verified that for each factor analyzed a different configuration was determined
