FIELD: powder metallurgy.
SUBSTANCE: invention relates to the production of metal powders using physical processes. It can be used for recycling metal products made using 3D printing. A sputtered metal anode in the form of a 3D printed product is immersed to a depth of 2-9 mm in a bath with an electrolyte in the form of a salt solution with a pH of 2≤pH≤11, which acts as a cathode. A voltage is set between the sputtered metal anode and the cathode in the range of 300≤U≤1500 V. After the discharge is ignited, the metal anode is raised above the electrolyte surface at a distance of 1-15 mm in manual or automatic mode, whereas sputtering to obtain a metal powder is carried out until the discharge stops burning.
EFFECT: obtaining a fine powder for use in 3D printing.
