Masao Torii, a second-year master’s student in the Graduate School of Engineering at KUAS, won the Best Presentation Award at the 2025 Japan Society for Precision Engineering Autumn Meeting for his research presentation titled “Mechanical Properties of 3D Printed Photocurable Resin Nanostructures: Effects of Sample Size and Printing Orientation.”
Under the guidance of Professor Takahiro Namazu (Faculty of Engineering; Specialization: Nanomechanics, Nanotechnology, Functional Materials), Torii-san used a nanoscale 3D printer to create photocurable resin nanostructures and successfully measured their Young’s modulus and fracture strength using their unique tensile testing technology. Torii-san clarified the effects of structure size and printing direction on these mechanical properties. Currently, nanodevices with a variety of functions are being proposed worldwide, and Torii-san’s results are expected to improve their reliability significantly.
Torii-san says, “My hard work, diligently conducting difficult experiments every day under Namazu-sensei’s strict guidance, has paid off. I feel great!” Professor Namazu praised Torii-san, saying, “This is all thanks to his hard work. I hope he will continue to work hard and complete an excellent master’s thesis.”
