This paper demonstrates the obtainment of the optimal parameters of production of a H13 tool steel by additive manufacturing in regard of porosity and cracking. The experimental analysis of 28 samples allowed the plotting of 2 charts that contain regions of the most efficient parameters of VED and travel speed that resulted in lower porosity and smaller crack length.

The effect of travel speed and laser power in the porosity and cracking of AISI H13 tool steel produced by adittive manufacturing
