AMにおけるシミュレーションによる事前評価と設計

抄録

This article summarized the recently published papers or books on the design for additive manufacturing (DfAM) from the standpoint of the numerical simulation or computer aided engineering (CAE), focusing on the laser powder bed fusion (LPBF) technique for metals. Chapter 2 described the state-of-the-art of the process simulation and topology optimization. Micro-CT image-based simulation is useful for the evaluation of real products, but for predictive simulation before manufacturing to be used in the design phase, probabilistic simulations are presented in Chapter 3. Finally, some recent reports on the Digital Twin are shown in Chapter 4.
