METHOD OF PRODUCING ARTICLES FROM COMPOSITE POWDERS Russian patent published in 2013 - IPC B22F3/105 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of articles from powder materials. It may be used for making complex-shape composite parts. Proposed device comprises bed 1 with location surface 2, platform 3 with working surface arranged inside said bed to reciprocate for distance equal to thickness of article functional layer 4, proportioning container 5 arranged for 2D horizontal reciprocation relative to platform 3, material compactor composed of shaft 6 arranged at base location surface, laser 7 mounted above said platform and software-hardware control complex 8. Proportioning container is composed of a set of cells 9 with outlets 10 made at their bottom. Outlet diameter makes (3-10) x d where d is powder granule diameter. Every said cell 9 is furnished with powder vibratory feeder.

EFFECT: expanded operating performances in using low-fluidity powders or with no fluid properties.
