Development of in-situ alignment of particles in digital light processing 3D printing

This Final Year Project aims to design an ultrasound-assisted set-up for Digital Light Printing (DLP) to align Iron (II, III) Oxide (Fe3O4) microparticles (IOMP) in resin and evaluate its effectiveness for DLP printing of Fe3O4-filler Shape Memory Polymer (SMP). The study examines the effect of vary...
