Abstract
Disclosed is a method for manufacturing a silicon carbide ceramic special-shaped part with a complex shape by plastic fused deposition modeling (FDM)-3D printing based on water debinding. The method includes: mixing graphite, carbon black, silicon carbide, and a surface modifier, and subjecting a resulting mixture to modification to obtain a surface modifier-coated composite ceramic powder; subjecting the surface modifier-coated composite ceramic powder with a macromolecular binder to internal mixing with an internal mixer to obtain a ceramic 3D printing feed; and subjecting the ceramic 3D printing feed to 3D printing, debinding, and reaction sintering in sequence to obtain the silicon carbide ceramic special-shaped part with the complex shape.
