Implication

Experimental study demonstrates multi-objective optimization of laser powder bed fusion parameters in Al6061 alloy, highlighting pathways to minimize porosity and crack densities.

Key Points

Simultaneous minimization of porosity and crack density is achievable in additively manufactured Al6061 alloy by adjusting laser power, scan velocity, and hatch spacing.
Multi-objective optimization coupled with machine learning techniques evaluated laser powder bed fusion parameters to identify conditions that mitigate microstructural defects.
Highlights the viability of real-time parameter tuning for laser powder bed fusion, though adaptive in situ monitoring remains essential to ensure component fatigue resistance.
