The invention discloses an additive manufacturing product and
powder treating
system and a working method thereof. According to the technical scheme, the
system is characterized by comprising a powdercleaning cabinet, wherein a
powder cleaning table is arranged in the
powder cleaning cabinet, a forming
barrel is placed on one side of the lower portion of the powder cleaning table, used old powderis contained in the forming
barrel, a vibrating screen used for screening the old powder or novel powder is arranged on the other side of the lower portion of the powder cleaning table, a material receiving
barrel used for receiving screened powder is arranged below the vibrating screen, a dust collection cabinet communicating with the powder cleaning cabinet is arranged outside the powder cleaning cabinet, a dust collection device is arranged in the dust collection cabinet, a powder recycling barrel and a powder mixing barrel are further arranged outside the powder cleaning cabinet, and a powder mixing device for fully mixing the novel powder and the old powder is arranged in the powder mixing barrel. According to the
system and the method, arrangement of the powder barrels is redesigned, the old powder and the novel powder need to be screened through the vibrating screen, coarse particles are prevented from entering mixed powder, purity and more recycling times of the mixed powder are guaranteed, and the surface quality of printing-formed parts is guaranteed.
