FIELD: printing.
SUBSTANCE: invention relates to 3D printing and can be used for creation of 3D articles. Method of 3D article 3D printing from metal powder material, includes pressing of powder metal material by electrode working surface with subsequent current supply, heating powder material and welding it to molded 3D article. Powdery metal material is supplied along electrode in enveloping air stream.
EFFECT: higher strength of articles, lower porosity, elimination of powder preheating.
