摘要

Abstract

Digital light processing (DLP) 3D printing enables high-resolution and efficient fabrication

yet achieving multimaterial printing with robust mechanical performance remains challenging due to limitations in the molecular design. Here

we report a photo-thermal dual-curing strategy to address this challenge. The photosensitive poly(oxime-urethane) resin

which forms ionic bonding between carboxylic acid and 2-(dimethylamino)ethyl methacrylate

exhibits excellent printability with low viscosity (below 5000 mPa·s)

high storage moduli after gelation (exceeding 10

Pa)

and high storage stability (over 30 days). The post-printing thermal curing between carboxylic acid and oxime-urethane bonds enables network rearrangement for mechanical enhancement and interfacial welding of modules with diverse properties. This dynamic chemical design facilitates high-performance multimaterial integration

significantly expanding the design flexibility and versatility for the fabrication of complex structures.
