Stereolithographic 3D Printing by Using Functional Ceramics Particles

Ceramics dendrites with spatially ordered micro cavities were successfully fabricated by three dimensional printing of stereolithography. Micro lattices pattern were propagated spatially in computer graphic. Ceramics nanoparticles dispersed photo sensitive liquid resins were spread on a grass substrate, and an ultra violet micro pattern was exposed to create cross sectional solid layer. The composite precursor formed by layer staking processes was dewaxed and sintered. Through this process, alumina photonic crystals with a diamond lattice structure were fabricated to control electromagnetic waves. Subsequently, solid electrolyte dendrites of yttria stabilized zirconia were fabricated for fuel cell miniaturizations.
