Abstract

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.
