| Abstract Scope |
In stereolithographic additive manufacturing (STL-AM), cross sections were created through photo polymerization on spread resin paste including nanoparticles, and models were sterically printed by layer lamination. As the row material of the printing, nanometer sized biological ceramic 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. Irradiation power was automatically changed for an adequate solidification depth for layer bonding. 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. |
