Abstract Scope |
A multi-scale ALE3D high fidelity model is developed to simulate directed energy deposition additive manufacturing. The model captures at a high fidelity the powder transport from the coaxial nozzle to the work piece as well as the effect of the carrier gas and laser ray tracing. The high cost of modeling is brought down by using deep learning and data driven reduced order modeling at different scales. The end goal is to combine modeling with a data driven (deep learning) approach for “first time right” also referred to as intelligent feedforward (IFF). We apply IFF to optimize laser power and scan speed to print complex large parts with overhang geometries, such as the Menger sponge, and obtain high density and geometric accuracy.
