Abstract Scope |
This work concerns the laser directed energy deposition (DED) additive manufacturing of stainless-steel parts. In this work, we achieved closed-loop control of the meltpool temperature. We demonstrate that maintaining the meltpool temperature at a steady state through closed-loop control of laser power leads to the following outcomes: (1) mitigation of microstructure heterogeneity, and (2) reduction in porosity of parts. |
