Dexel-Based Simulation of Directed Energy Deposition Additive Manufacturing

Additive manufacturing is typically a flexible alternative to conventional processes. However, costs increase due the effort required experimentally determine optimum process parameters for customized products or small batches. Therefore, simulation models are needed in order reduce amount of necessary experimental testing. For this purpose, novel technological method directed energy deposition additive presented here. The Dexel-based allows modeling varying geometric shapes by considering multi-axis machine tool kinematics and local conditions. approach can be combined with subtractive processes, which enables integrated digital chains.
