... and tested on numerical simulations based on the discontinuous Galerkin finite element method for the direct energy deposition AM process. The results shows that the model maintains 0.983 − 0.999 R 2 over geometries not included in the training data, which is higher than convolutional neural networks...

...Jihoon Jeong; Samantha Webster; Rujing Zha; Jon-Erik Mogonye; Kornel Ehmann; Jian Cao The process parameters of Directed Energy Deposition (DED) have been widely studied including laser power, powder flow rate, and scanning speed. These parameters affect clad dimension and melt pool temperature...
