Abstract
In the industry, the need to reduce the manufacturing cost and CO2 emissions makes structural optimization an important computational tool to develop and design products with the required and necessary mechanical properties and as light as possible. Additive manufacturing is nowadays used to produce structural optimized products due to the possibility of producing complex shapes with high accuracy. In this work, a topology software developed by the research team and an already validated commercial software capable to structurally optimize a structural component and deliver its prototype are used. A cross-analysis was performed to validate and compare the results. Advanced numerical discretization techniques combined with algorithms of evolutionary structural optimization were applied in the process. Several optimized structures were produced using FFF technology and experimentally tested. The chosen material was PLA with a Young’s modulus of 3145 MPa. It was verified that the optimization tools are suitable to reduce the parts weight and, at the same time, maintain the structural performance. Thus, it is expected to reduce the part costs and the CO2 emissions resulting from their production with this approach, without risking the required mechanical properties.
