Three Dimensional Printing of Metals and Ceramics Graded Dendrites for Energy and Material Flows Modulation

Full Article:

Artificial ceramic dendrites were successfully fabricated by three dimensional printing of stereolithography. The ceramics nanoparticles were dispersed in to photo sensitive liquid resins were spread uniformly by a mechanical knife edge. The cross sectional pattern was formed through illuminating visible laser. The high resolution image could be achieved by a digital micro mirror device. The solid micro structures were built by stacking these patterns. The formed precursors with dendrite structures were dewaxed and sintered in air atmosphere. By utilizing stereolithography, micro photonic crystals with diamond lattice structures composed of alumina or copper were fabricated. Subsequently, solid electrolyte dendrites of yttria stabilized zirconia with spatially ordered porous structures were fabricated for fuel cell miniaturizations. Moreover, artificial bones of hydroxyapatite scaffolds with dendritic lattice structures were modeled successfully to realize excellent biological compatibilities. Graded porous structures in the artificial bones were processed as novel tissue engineering.
