Abstract

In this paper, we propose a new method of fabricating 3-D models of the high-temperature structural materials such as ceramics by selective laser sintering (SLS). To save the laser energy, we adopted the combustion synthesis which is the exothermic reaction between the raw materials. By adding chemical reaction heat to laser heat, the particles of the products of the reaction were bonded together by relatively low laser energy. The combinations of the raw materials and the laser scanning conditions for solidifying the products and laminating the solidified layers were investigated experimentally. Since burning in the furnace is unnecessary in the proposed method, it is possible to fabricate the models in a short time.
