Manufacturability-Based Design Optimization for Directed Energy Deposition Processes

Additive Manufacturing (AM) is the process of joining materials by selectively depositing them layer upon for purpose manufacturing parts or assemblies which are based on a 3D digital model. The nature these processes results in morphing complex component geometries, enabling high degree design freedom and resulting lightweight structures with increased performance. These processes, however, experience many limitations regarding manufacturability. aim this study to develop method tool that optimizes avoid overhanging geometries need supports during process. A workflow consisting steps topology optimization, orientation material addition, machine code generation described implemented using Rhinoceros Grasshopper software. proposed compared conventional Key Performance Indicators (KPIs) such as part volume, support build time. significant reduction observed all KPIs method. Examining from both one, it clear latter has unquestionable advantages terms effectiveness. In particular case presented, total volume around 80% observed. (including required volume) leads used well time, consequently cost reduction.
