FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of articles from metal powders. Mixture of metal powder with binder is prepared in form of a paste in ratio: 78–82 % of metal powder, 18–22 % of binder. Liquid glass is used as binder, and cast iron chips are used as metal powder. Formation of billet by digital model is carried out layer by layer by means of extrusion printing on 3D-printer. Produced billet is sintered and impregnated with bronze.
EFFECT: production of articles by non-pressed powder sintering is provided.
