At the stage of computer modeling at the CAD/CAE level, there are open perspectives of subsequent reproduction of smart 3D structures via SLS. These materials can find their application in the aerospace, chemical, and nuclear power industry. In this case, an SHS reaction is only initiated within a spot of focused laser beam that is scanned over the surface of a powder mixture until formation of a desired computer-designed configuration. At present study, our experimental results by SLS have been described for the following SHS oxide systems:· mixture of oxides for synthesis of ceramics: TiO2 + ZrO2 + PbO, Al(Al2O3) + Zr(ZrO2);
· mixture of oxides for synthesis of ferrites: BaO2 + Fe2O3 + Cr2O3 + Fe, Li2CO3+ Fe2O3+Cr2O3+Fe.
· high-temperature superconductivity oxide ceramics YBa2Cu3O7, SrFe12O19.
Optimization of the process of 2D and 3D computer-aided prototyping is discussed with emphasis on synthesis of 3D parts. It was emphasized, that PZT and ferrites systems are more perspective for synthesis of functionally graded tools and MEMS.
