Within laser directed energy deposition (LDED) process, research has expanded into using a combination wire-powder feed to combine multiple materials within the process to produce materials with enhanced properties. The objective of this study was to reconstruct a complex wire-powder LDED process for numerical simulation. Deconstruction of the process and calibration of each component was executed to uncover the closest approximation and optimization for conversion from equipment setup to model. Laser parameters coupled with wire angle conversion were shown to contribute to significant output variations, while powder feed settings had little effect on output measurements. Although one specific process setup was investigated, the simulation demonstrates that a six-laser, three-powder feed, single wire process can be simulated using a single laser, two-powder feed, single wire configuration. By exploring the approach to simulate the wire-powder LDED process, we evaluate the ability to produce bimetals using two material feedstocks in a LDED process.
