METHOD OF THE PRODUCT MANUFACTURING BY THE ROLL POWDER SINTERING Russian patent published in 2018 - IPC B29C67/04 B29C43/48 B29C64/153 B29C64/245 B29C64/393 B33Y10/00 

FIELD: metallurgy.

SUBSTANCE: method relates to the field of powder metallurgy, in particular to the three-dimensional objects layer-by-layer manufacturing method by means of powder sintering, and can be used in the composite products manufacturing to create the model tooling for the casting processes, machine building and instrumentation products, scientific research products physical models, created on the basis of technical data obtained through the computer-aided design systems. Method is based on the articles creation by the various powders or powders combinations sintering placed into the perforated, soluble, compressible tape during its rewinding, and enables the creation of products with complex structure under the winding off system control.

EFFECT: technical result of the invention consists in increase in the products formation accuracy and speed, improving their quality, strength, uniformity, reducing the surface roughness and manufacturing cost.
