Additive manufacturing (AM) technologies in metallic materials have experienced significant growth over recent decades. Concepts such as design for additive manufacturing have gained great relevance, due to their flexibility and capacity to generate complex geometries with AM technologies. These new design paradigms make it possible to save on material costs oriented toward more sustainable and green manufacturing. On the one hand, the high deposition rates of wire arc additive manufacturing (WAAM) stand out among the AM technologies, but on the other hand, WAAM is not as flexible when it comes to generating complex geometries. A methodology is presented in this study for the topological optimization of an aeronautical part and its adaptation, by means of computer aided manufacturing, for WAAM manufacturing of aeronautical tooling with the objective of producing a lighter part in a more sustainable manner.

用于拓扑优化航空夹具的电弧增材制造工艺


近几十年来，金属材料的增材制造 (AM) 技术经历了显着的发展。增材制造设计等概念因其灵活性和利用增材制造技术生成复杂几何形状的能力而获得了很大的相关性。这些新的设计范例可以节省材料成本，实现更可持续和绿色的制造。一方面，电弧增材制造 (WAAM) 的高沉积速率在增材制造技术中脱颖而出，但另一方面，WAAM 在生成复杂几何形状时并不那么灵活。本研究提出了一种通过计算机辅助制造对航空零件进行拓扑优化及其适应的方法，用于航空工具的 WAAM 制造，目的是以更可持续的方式生产更轻的零件。
