PRODUCTION DEVICE USING SLOTTED EXTRUSION HEAD AND METHOD OF MANUFACTURING Russian patent published in 2020 - IPC B29C64/118 B29C64/20 B33Y10/00 B33Y30/00 

FIELD: additive production.

SUBSTANCE: claimed group of inventions relates to device and method of additive production. Device extrudes radiation-hardened construction material above bearing surface using a slit extrusion head for depositing a layer of extruded structural material above the support surface. Radiation is selectively projected by means of a projection unit into the production area between the support surface and the slotted extrusion head, thereby curing parts of the extruded construction material. Device repeats these stages until the required object is formed by adjacent hardened parts of the structural material passing through the layers and between the layers.

EFFECT: technical result of claimed group of inventions is production of objects of complex geometric shape with increased speed of production and/or with reduction of material losses.
