Abstract Scope |
This study investigates the process capability comparison of two metal additive manufacturing (AM) technologies, i.e., laser powder bed fusion (L-PBF) and metal binder jetting (MBJ), through geometric feature build plates manufactured with similar baseline variations. The geometric feature plate integrates standard ISO/ASTM test artifact geometries that include, but are not limited to, horizontal holes, varying angled walls, vertical features incorporating concentric hollow cylinders, protruding cylinders, etc. All the geometric features in the feature plate were kept the same for both L-PBF and MBJ technologies and were designed following the DfAM guidelines for successful fabrication. Optical and mechanical measurement methods were employed for all the features in the build plate. Obtained results were analyzed for each feature and compared for both technologies with a detailed evaluation. The difficulties experienced during the feature plate fabrication are discussed in detail for both processes, and comments are made regarding strategies to overcome them. |
