Effect of non-reactive diluent on defect-free debinding process of 3D printed ceramics

Defect-free three-dimensional (3D)-printed ceramics, such as alumina, zirconia, and titania, have been successfully fabricated by controlling the initial defect formation using a non-reactive diluent, namely, polypropylene glycol (PPG), as an additive in the photocurable resin. By crosslinking with...

Description
Summary:Defect-free three-dimensional (3D)-printed ceramics, such as alumina, zirconia, and titania, have been successfully fabricated by controlling the initial defect formation using a non-reactive diluent, namely, polypropylene glycol (PPG), as an additive in the photocurable resin. By crosslinking with uncured monomers in 3D-printed ceramic green bodies, PPG prevented them from evaporating early, which often results in defect formation at low temperatures (
