Micro-CT scans of additively manufactured AlSi10Mg cylinders

All three cylinders were fabricated using the same process parameters, which are: scanning speed of 1250 mm/s, hatch distance of 150 µm, and layer thickness of 50 µm. The difference is that batches 1 and 2 were fabricated with a focused beam, while batch 3 was fabricated with a negative laser beam defocus.

Additionally, a stainless steel wiper blade was used for batch 1, whereas a carbon fiber wiper blade was used for batches 2 and 3. The micro-CT scans reveal defect conditions in these samples. In particular, micro-CT-based porosity analysis enables a deeper understanding of the effects of different parameters in PBF-LB fabrication of AlSi10Mg.</p><p dir="ltr">All details of this dataset are provided in the associated thesis (Title: Imaging and image enhancement of additive manufacturing defects) and manuscript (Title: Porosity reduction in laser powder bed fusion of AlSi10Mg through laser beam defocusing).
