Ceramics dendrite structures with geometrically ordered lattices had been created successfully by using a laser scanning and micro patterning stereolithography. Micro rods of alumina, zirconia, titania and hidroxiapatite were connected to realize coordination numbers of four, six, eight and twelve 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 can be applied to novel censor devices, composite materials, solid electrodes and biological implants in the near future. In this paper,fabrication processes of ceramic dendrites and numerical simulations of spatial gas flows, electromagnetic wave propagations and biological fluid flows will be discussed for novel energy production devices and biocompatible implants.
