High‐resolution <scp>3D</scp> printing resin reinforced by polyurethane filler particles; physical and mechanical properties

Abstract In 3D printing technology, unwanted resin properties such as low mechanical, thermal, electrical, and biocompatibility can be enhanced by using proper fillers. this study, sucrose urethane microparticles, acrylic modified are used to improve the of final object without losing other resolution. Modification is confirmed FTIR spectroscopy hydrogen bonding index enhancement after modification filler. Filler particles reduced in sizes followed ball‐milling scanning electron microscopy. When filler content 2.5 wt%, mechanical tensile flexural modulus increase compared neat however, increases brittleness photo‐cured samples. Thermal degradation temperature lifted up for 2.5–5.0 wt% loading resin. Improved dimensional accuracy detailed higher resolution, due physical effect particles, also achieved real 3D‐printed explored. Highlights High‐resolution printing, random geometry Scattering from polyurethane foam microparticles lead high‐resolution printing. Acrylate‐modified provide compatibility. Polyurethane leads resolution with properties.
