About

Shoji Maruo is a pioneering researcher at the intersection of optics, photonics, and additive manufacturing, with a core focus on advancing 3D printing technologies through light-based methods. His major contributions include developing novel photoresist materials and optical techniques for high-precision 3D additive manufacturing, as well as creating robotic systems that bridge digital design and physical assembly. Notably, Maruo has explored the two-way relationship between optics and 3D printing—using light to enable printing and printing to manipulate light—as highlighted in his 2020 feature issue introduction (5 citations). He also introduced a groundbreaking “3D block printer” that automatically converts CAD models into toy brick sculptures, with a robotic system that plans and assembles block structures from digital designs (2016, 4 citations; 2017, 2 citations). This work demonstrates his innovative approach to merging robotics, computer-aided design, and tangible construction. With a career dedicated to pushing the boundaries of what 3D printing can achieve—from microscale optical devices to large-scale block assemblies—Maruo’s research continues to inspire new directions in manufacturing, education, and interactive design.
