Abstract
A method for producing an article containing silicon carbide as the main constituent includes a plurality of sets of steps of forming a layer of a raw material powder and irradiating the layer with laser light according to three-dimensional model data. The low material powder is a mixture of silicon carbide powder, metallic silicon powder, and carbon powder. The laser light used in the step of irradiation with laser light has a spatial laser power density of 11 J/mmto 50 J/mm.
