FIELD: technological processes.
SUBSTANCE: group of inventions relates to laser sintering of metal powder. Laser sintering device for building up a metal part from metal powder includes a laser beam generator, means for deflecting beam to scan a surface of part, a sintering pan including a metal powder used to thicken part by melting metal powder with laser beam, and at least one means for induction heating of metal powder contained in area of said sintering pan. Disclosed is a method of laser sintering for build up of metal part from metal powder, as well as device and method of laser sintering for making a metal part of metal powder.
EFFECT: reduction of residual stresses after hardening part.
