Zusammenfassung:	The utility model discloses an SLM type 3D printer powder recovery structure which comprises a powder receiving member and a powder collector, and the top end of the powder collector is connected to the bottom end of the powder receiving member through a thread structure. The inner wall of the powder receiving piece is in an inverted cone shape and is of a smooth surface structure, the top end ofthe powder receiving piece is square, a sealing ring is arranged on the top end face, and a sealing belt is further arranged at the top end of the powder collector. According to the designed powder recovery structure, the powder receiving structure with the smooth inverted cone is adopted, so that powder falling into the powder receiving piece can be smoothly drawn into the powder collector, and the accumulation phenomenon is avoided. Due to the square design, powder in the width direction of the printing cabin can be fully covered and recycled. And the design of the sealing ring and the sealing belt can ensure that t
