Abstract
In stereolithographic additive manufacturing （STL-AM）, 2-D cross sections were created through photo polymerization by UV laser drawing on spread resin paste including nanoparticles, and 3-D models were sterically printed by layer lamination. The lithography system has been developed to obtain bulky components with functional geometries. As the row material of the 3-D printing, fine metal particles were dispersed into acrylic liquid resins at about 60% in volume fraction. These materials were mixed and deformed to obtain thixotropic slurry. The resin paste was spread on a glass substrate with 50 μm in layer thickness by a mechanically moved knife edge. An ultraviolet laser beam of 355 nm in wavelength was adjusted to 50 μm in variable diameter
and scanned on the spread resin surface. The composite precursors including nanoparticles were dewaxed and sintered in the air atmosphere. Through computer-aided smart manufacturing, design, and evaluation （Smart MADE）, practical material components were fabricated to modulate energy and material transfers in potential fields between human societies and natural environments as active contributions to Sustainable Development Goals （SDGs）.
