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 varying ultrasound radiation duration on the alignment of IOMP in the resin and their mechanical properties.
The project evaluates multiple design concepts based on effectiveness of alignment, modularity, durability and ease of fabrication. The selected design is fabricated and evaluated for its effectiveness in aligning Fe3O4 particles in the resin and printing them. The experiment uses various methods, including the cure depth test to examine printing properties, visual inspection to observe alignment patterns, and the tensile test to determine mechanical properties.

The ultrasound-assisted set-up for DLP successfully prints ultrasound radiated and aligned IOMP in resin, producing better mechanical properties compared to the neat resin and IOMP resin without ultrasound radiation. This project designs and fabricates an ultrasound-assisted set-up for DLP 3D printing and evaluates the effectiveness of aligning IOMP in the resin. |
