FIELD: process engineering.
SUBSTANCE: invention relates to laser facing and alloying and may be used in stereolithography with application of powder materials. Proposed device comprises laser coupled optically with circular beam generation system and focusing system, and system to feed material to be applied in the form of tube. Focusing system represents conical prism to produce conical laser beam. Material feed system is arranged along focusing system optical axis. Said focusing system has annular spherical lens with optical axis aligned with that of conical laser beam. Its focus is located on article surface.
EFFECT: higher efficiency powder utilisation factor.
