Postprocessing Study for the Controllable Structures of

For indirect ceramic additive manufacturing (AM), green parts' initial densities are low, limiting the postprocessing strengthening under atmospheric pressure. This study employed binder jetting printing (BJP) based on the polycondensation curing of urea-formaldehyde resin to produce series of Al 2 O 3 green specimens with controllable structures.
