43% Porosity Decrease Exposes Hidden Process Optimization Secrets
Optimizing laser power, scan speed, and hatch spacing can cut porosity in high-entropy alloy (HEA) laser-directed metal deposition (LMD) builds by up to 35%, boosting tensile strength and meeting ASTM A383 standards. In a recent DOE LMD campaign, 24 experimental runs revealed a 35% porosity drop while increasing tensile strength
