Abstract: The present invention relates to a method of producing a SiC—Si composite component. The method includes preparing a first molded body containing SiC particles by a 3D printing method, wherein the first molded body has a first average pore diameter M1;

forming a second molded body, in which the first molded body and a dispersion containing carbon particles are brought into contact so that the pores are impregnated with the carbon particles, wherein the carbon particles have a secondary particle having an average particle diameter M2, and the carbon particles satisfy the following formula:




M2≤M1/10; and

forming a SiC—Si composite component by carrying out that the second molded body is impregnated with a metallic si and is reactively sintered;
wherein the content of Si is in the range of 5% by mass to 40% by mass in the SiC—Si composite component.
