The invention provides a powder removal and recovery device for a 3D printing product. The powder removal and recovery device comprises a powder removal box body, a rotating device, a fixing device, avibrating device and a powder recovery hopper, wherein the powder removal box body is provided with a powder removal cavity of which the opening faces downwards; the rotating device comprises a supporting frame and a rotary shaft extending in the transverse direction, and the rotary shaft is rotationally arranged on the supporting frame; the fixing device comprises a product bearing plate and connectors, the product bearing plate is fixedly connected with the rotary shaft, and the connectors are used for fixing the 3D printing product or a machining substrate to one side surface of the product bearing plate; the vibrating device is arranged on the other side surface of the product bearing plate; and the powder recovery hopper is provided with a big-end-up powder collecting cavity, the large-opening end of the powder collecting cavity communicates with the opening of the powder removal cavity, and the small-opening end of the powder collecting cavity forms a powder outlet. The powder removal and recovery device can shake off and recycle powder on the 3D printing product, accordingly, a lot of powder for 3D printing can be saved, and explosion hidden danger caused by powder flying is eliminated.
Description
technical field [0001] The invention relates to 3D printing technology, in particular to a powder removal and recycling device for 3D printed products. Background technique [0002] At present, due to the complex shape of 3D printed products (usually metal 3D printed products), there are many dead ends, and even support connectors are printed between the 3D printed product and the processed substrate, resulting in a lot of powder (such as metal powder, etc.) remaining on the product. , Support the dead corner of the connecting piece, resulting in a lot of waste of powder. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a powder removal and recovery device for 3D printed products, which can shake off and recycle the powder on 3D printed products, thereby saving 3D A large amount of powder for printing eliminates the potential explosion hazard caused by...
