Additive manufacturing product and powder treating system and working method thereof

Abstract

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.

Description

【Technical field】 [0001] The invention relates to an additively manufactured product, a powder processing system and a working method thereof. 【Background technique】 [0002] All the discrete equipment required by the existing laser sintered additive manufacturing system for industrial-grade 3D printers, including powder lifting trolleys, powder cleaning platforms, powder adding buckets, ejector mechanisms, powder screening mechanisms, recycling powder buckets, waste powder Buckets, new powder buckets, powder mixers, powder feeders, powder weighing devices, and dust collectors and other equipment and facilities are all separated, and the plastic powder used is ultra-fine powder with excellent fluidity Generally, the diameter of powder particles is 10 to 100um in diameter. At present, the operator completely manually transfers the powder from one equipment container to another equipment container from each discrete equipment to complete powder recovery, new powder feeding, an...

AI Technical Summary

Problems solved by technology

[0004] 1. The volume is large, and the floor area is still large;

[0005] 2. The new powder used for powder mixing has not passed through the powder sieving machine, which will cause the large particles formed by the agglomeration of the fine powder during transportation to be unable to be screened out, resulting in the mixing of large particles into the mixed powder, which will affect the printing stability and the surface of the printed product. Effect

[0006] 3. When the old powder bucket is full, it cannot be sent out of the machine, which will affect the subsequent process

[0007] 4. The efficiency of powder feeding is relatively low, the amount of compressed air required is relatively large, and the noise is relatively large

[0008] 5. When the wrong powder is added to the feeding bucket, it cannot be removed outside the machine
