Abstract:
3D Metal Binder Jetting is currently disrupting manufacturing and accelerating mass production of 3D-printed parts. Its excellent balance between part quality and productivity rates is founded on powerful R&D investigations and metrics development to support applications for industrial cases. In this study, the technical physics description of the binder jet fundamentals and its role on parts consolidation will be explained. In particular, the focus will be on describing novel metrics of green parts microstructure obtained by scanning electron microscope (SEM) and X-ray computed tomography (XCT) as binder and porosity local fractions and their spatial distributions. These unique metrics will be evaluated for different powders and R&D print modes. The use of this set of metrics to support print mode development and materials integration, as a predictive and more sustainable method will be discussed.
