| Zusammenfassung | The industrial adoption of Powder Bed Fusion with Laser Beam of Metals (PBF-LB/M), alongside specialized equipment tailored for different alloys and applications, necessitates a neutral, open benchmark to assess fabrication quality across different setups. This study aims to close the gap in the VDI 3405 Part 2.1 database for geometric dimensioning and tolerancing (GD&T) of AlSi10Mg. To this end, a modular test artifact is developed in collaboration between BAM and PTB. It addresses current geometric resolution limitations observed in a representative machine fleet, including machines from Nikon SLM, EOS, DMG Mori, and Aconity, as well as ensuring mandatory accessibility by various Non-Destructive Testing (NDT) methods. Designed according to DIN ISO/ASTM 52902, the artifact enables seamless communication of its geometry and facilitates the sharing of its Computer Aided Desing (CAD) model. To evaluate practical implications, an EOS M 300-4 and a DMG Mori Lasertec 30 are used to fabricate the artifact. The PBF LB/M machines are calibrated per DIN ISO/ASTM 52930, using Original Equipment Manufacturer (OEM) qualified powder and corresponding parameter sets to replicate an industrial production environment. However, the evaluation of features used to describe the test artifact can be significantly affected by measurement procedure and its uncertainty. To mitigate variations, a test plan is established for X-ray Computed Tomography (XCT) and tactile surface roughness measurement, subsequently executed with devices from different OEMs. Preliminary results of the small Round Robin study provide insights into achievable geometric accuracy of AlSi10Mg, establishing a foundation for benchmarking PBF-LB/M machines and homogenizing performance across machines. |
