In stereolithographic additive manufacturing (STL-AM), 2-D cross sections were created minutely through photo polymerization by UV laser drawing on spread resin paste including ceramic nanoparticles, and 3-D models were sterically printed by layer lamination. Designed models with intended 3-D structures were converted into the stereolithography file format through polyhedral approximations and sliced into a series of 2-D layers. The slicing pitches were defined as 50 μm for laser scanning stereolithography. The numerical data were transferred into each stereolithographic system to create raster patterns for laser scanning. The lithographic system has been developed to obtain bulky ceramic components with functional geometries. An automatic collimeter was newly equipped with the laser scanner to adjust beam diameter. Fine or coarse beams could realize high resolution or wide area drawings, respectively.
