Binder jet printing (BJP) is a flexible additive manufacturing platform capable of producing complex geometries from diverse materials. However, developing new material systems and optimizing processing conditions in BJP is costly and time-consuming. This study introduces a modified molding technique to produce comparable green parts that can be integrated into BJP’s process flow, enabling rapid screening of de-binding and sintering conditions without burdening production printers. Leveraging powder slurry mixture and flexible molds, we fabricated molded green parts with densities of 55–65% similar to typical BJP parts. Following burnout and sintering at 1150–1350°C, the final parts achieved 89–98% density and tensile strengths of 350–550 MPa, comparable to BJP counterparts. The method also allowed evaluation of sintering additive effects, with BN promoting densification via liquid-phase formation. Overall, this approach provides a fast, scalable, and cost-effective proxy for material and process development in BJP. |
