Fig. 1: 3D PIPS printing mechanism of functional objects.
From: Direct printing of functional 3D objects using polymerization-induced phase separation
a Schematic of the phase separation of AgND induced by PIPS (left) depicting the AgND functional material phase separating from the polymer object to the interface during 3D printing using an SLA printer (right). b The tuning of phase separation is controlled with crosslinker molecular weight and percent crosslinker to alter the crosslinking density and polymer gelation rate to yield different morphologies in 3D objects. Representative SEM images are presented to depict the composite, gradient or coating morphologies. c Photographs of PIPS induced 3D printed and sintered Ag coated lattice objects with dimensions of 40 × 40 × 40 mm.
