Binder-based ceramic manufacturing is an integral technique for fabricating intricate ceramic structures. However, the debinding process poses a significant challenge, due to the time for binder removal increasing with the square of the part thickness, and excessive pressure buildup that can lead to cracks in the part. We have explored the use of mass transport networks to accelerate debinding and reduce pressure buildup. These networks can be selectively incorporated using additive manufacturing. This work focuses on multiphysics modeling to design networks and extrusion-based additive manufacturing of ceramic green bodies to validate this approach. Addition of appropriately selected mass transport networks can reduce the maximum pressure to below the critical pressure. The binder diffusion rate increases due to the network, enabling faster debinding times. This innovative approach enables faster processing and successful fabrication of larger structures, offering significant energy and cost savings while expanding design possibilities.
