Thermal Monitoring for Process Control and Parameter Correlation in Laser Powder Bed Fusion of AlSi10Mg

Abstract

Laser Powder Bed Fusion (L-PBF) of AlSi10Mg is challenged by rapid thermal transients and high diffusivity. This study applies a microbolometer-based thermal monitoring system to correlate laser power, scan speed, and build position with thermal features. Results demonstrate reliable detection of defects such as keyhole porosity, supporting real-time process control and quality assurance.
