Morphological study of ۳D printed foam-like polyurethane using ip-۳Dprinting

Immersion precipitation ۳D printing (ip-۳dp) is an innovative technique that leverages nonsolventinducedphase separation to fabricate complex ۳D structures. Due to exchange of solvent andnonsolvent, porous structures can be obtained without any additives or sacrificial materials. In highexchange rate of solvent and nonsolvent, spinodal decomposition takes place and finger-likemorphology can be obtained. In low exchange rate, nucleation and grow phase separation becomedominate and tiny pores create. Herein we present the effect of nonsolvent in morphology and strandsuniformity.
