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