FREEFORM FABRICATION OF CERAMICS DENDRITES FOR FLUCTUATION MODULATIONS IN ENERGY AND MATERIAL FLOWS

Ceramics dendrite structures with geometrically ordered lattices had been created successfully by using a laser scanning and micro patterning stereolithography of spatial joining techniques. Micro rods of alumina, zirconia, titania and hidroxiapatite were connected to realize four, six, eight and twelve coordination numbers for fluctuation modulations of electromagnetic wave, electronic current propagation, heat diffusion, stress distribution, liquid flow and gas dispersion. Intensity profiles of these energy fields and material densities were visualized theoretically though finite element methods to compare with measured results. Technological concepts of these ceramics dendrites will be applied to novel censor devices, composite materials, solid electrodes and biological implants in near future industrial and medical fields. In this paper, fabrication processes of ceramic dendrites and numerical simulations of spatial gas flows or electromagnetic wave propagations will be discussed for novel energy harvesting devices.
