Beschreibung
Zusammenfassung:	The utility model discloses a device for preparing metal spherical powder for 3D printing. The device comprises a stock bin, a powder feeding mechanism heating barrel, a gradient temperature barrel, a first collecting barrel and a second collecting barrel which are sequentially connected in series. A powder feeding pipe is connected between the powder feeding mechanism and the heating barrel, an inner cavity of the heating barrel is communicated with an inner cavity of the gradient temperature barrel, an air feeding mechanism is arranged at the inner bottom of the gradient temperature barrel, a first screening net is arranged in the gradient temperature barrel, and the inner cavity of the gradient temperature barrel is vertically divided into a high-temperature area and an evaporation area through the first screening net. The evaporation area and the upper side of the inner cavity of the first collecting cylinder are connected with a condenser pipe, the upper side of the inner cavity of the condenser pipe and
