FIELD: process engineering.
SUBSTANCE: proposed method comprises making the 3D model of article, its division to plies in cross-section, application of powder, application of model cross-section pattern on powder by liquid binder, ply-by-ply solidification of powder in 3D model unless cycle completion. Powder consists of the mix of fine and granular heat-resistant materials. Mixing is performed in mixing runners to homogeneous bulk. Said liquid binder represents the solutions of magnesium salts and/or organic binder and/or hydraulic binder. Obtained article is cured for at least 2 hours and, then, dried. Carbon component, a plasticiser, can be added to said powder. Produced article can be heat treated at, at least 180°C.
EFFECT: complex shape refractory articles with isotropic properties.
