Laser based powder bed fusion for metals (PBF-LB/M) is an industrial additive manufacturing (AM) method offering high -precision manufacturing for complex geometries. However, comparing the performance of different PBF-LB/M machines remains difficult, especially when machines are from different manufacturers. This study introduces a new benchmark artifact with standard features for facilitating the evaluation and comparison of machine performance. Two industrial PBF-LB/M machines, EOS M290 and Aconity3D MIDI+, were used to fabricate the part under similar conditions. The additively manufactured (AMed) samples were then inspected using 3D scanning metrology tools, and the results were analyzed using a method called root mean square deviation (RMSD) to measure how far each feature deviates from the original design. The results showed apparent differences in how each machine handled certain features and provide useful information for choosing the right machine based on part geometry.
