The utilization of pore forming agents (PFAs) in digital light processing (DLP) 3D printing to manufacture porous ceramics through their thermal decomposition has received a great deal attention. Nevertheless, even though the inner PFA microstructure green body is an essential precondition for tailoring properties ceramics, approaches established date have only focused on post-processing. To address this gap, present study demonstrates novel DLP approach elucidate how PFAs are formed bodies during printing. Specifically, complex UV scattering patterns that common composite and often detrimental were exploited modify interface between ceramic-polymer matrix. This was done modulation size difference as well DLP's process parameters. Additionally, method inferring interfacial embedded surface characterization proposed.
