µCT data of additively manufactured downskin surface test specimens according to DIN EN ISO/ASTM 52902 for 316L and CuCrZr

This dataset contains micro-computed tomography images of selected additively manufactured (powder bed fusion of metals using a laser beam, PBF-LB/M) downskin surface test specimens in accordance with DIN EN ISO/ASTM 52902:2020-05. Individual scans of flat tabs with downskin angles of 15° were acquired per material to ensure comparability.

• Materials: 316L (Carpenter Additive) and CuCrZr (Eckart TLS GmbH)
• Downskin Angle: 15°
• PBF-LB Machine: Aconity MIDI+ equipped with an integrated Aerosint SPD Recoater V1.0
• µCT Scanner: Bruker SkyScan 1275
