Overview

This study demonstrates how laser thermography identifies defects in AlSi10Mg parts, suggesting a viable non-destructive method for inspection.

Key Points

  • Laser thermography successfully detects defects in AlSi10Mg parts produced by Laser Powder Bed Fusion.
  • Thermographic tests identified defects introduced by varying printing parameters, validating the effectiveness of this method.
  • Micro-computed tomography assessed defect geometry, revealing deviations from nominal shapes in the manufactured parts.
  • While thermography has limitations, it presents a cost-effective alternative to traditional micro-computed tomography for inspections.
