Predictive modeling of solidification during laser additive manufacturing of nickel superalloys: recent developments, future directions
TL;DR: In this paper, a multiscale modeling and simulation of additive manufacturing processes is presented, where the critical issues in this process are linked with multiphysics (such as fluid flow and diffusion of heat and mass) and multi-scale challenges that arise due to localized rapid heating and cooling during AM processing.

TL;DR: 3D metallic parts of mild steel wire are built with a WAAM process by depositing layers of material on a substrate of a S235 JR steel sheet of 3 mm thickness under different process conditions, and CMT Continuous is the optimal option as the mechanical properties are better than single CMT.
