FIELD: powder metallurgy, namely manufacture of three-dimensional metallic articles of complex configuration with use of selective inhibiting of sintering.
SUBSTANCE: method comprises steps of layer-by-layer application of metallic powder; before applying next layer inhibiting sintering of one or several zones in applied layer; then pressing material for producing powder blank; sintering it; removing out of produced blank one or several sintered sections in boundary of inhibiting. Steps pressing and sintering may be performed after applying each layer. Apparatus for performing the method includes unit for applying layers, unit for inhibiting sintering, press and furnace.
EFFECT: possibility for producing dense high-accuracy metallic articles.
