FIELD: process engineering.
SUBSTANCE: invention relates to layer-by-layer production of parts from metal powders. This nozzle is produced by copper powder sintering by laser focused beam. Copper powder is preheated to 150°C and fed from batching bin. During layer-by-layer sintering of copper powder temperature in batching bin is kept constant. After sintering of every layer, nozzle surface is cleaned by focused laser beam of power making 25% of laser beam power at sintering.
EFFECT: production of precise complex shape parts of required strength.
