Abstract Scope This study investigates the dimensional tolerances of part fabricated by two metal additive manufacturing (AM) technologies, i.e., laser powder bed fusion (L-PBF) and metal binder jetting (MBJ), by fabricating a geometric feature build plate. The geometric feature build 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 parts in the feature build plate were kept the same between L-PBF and MBJ technologies. Optical and mechanical measurement methods were employed for all the features in the build plate. Obtained results were analyzed for different features and compared between both technologies. The difficulties experienced during the feature build plate fabrication are discussed in detail for both processes, and suggestions are made regarding strategies to overcome them.
