DEVICE FOR LAYER-BY-LAYER MANUFACTURING OF THREE-DIMENSIONAL ARTICLES FROM TWO AND MORE POWDER COMPONENTS Russian patent published in 2019 - IPC B22F3/105 B29C64/321 B33Y30/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a device for layer-by-layer manufacturing of three-dimensional articles and can be used for production of three-dimensional articles from two or more dissimilar powder components. Device comprises a construction chamber, a construction platform, powder feeders, a laser device for programmable layer-by-layer laser fusion of a given region in each layer, device for leveling powder layer on construction platform, powder removal device from layer. Device for leveling the powder layer on the construction platform is made in the form of a beam placed in guides, with which a leveling element is connected. Device for removal of powder from layer is made vacuum with inlet slot hole and is fixed to beam of device for leveling powder layer, powder feeders are made with slotted outlet holes, beam is made with slot channel, wherein inlet slot of device to remove powder from layer, leveling element, slot channel of beam and outlet holes of feeders are parallel to each other.

EFFECT: higher accuracy of geometric dimensions of manufactured three-dimensional item.
