3DP (3D Print) is currently the rapid prototyping method that is commercialized in 3D printing. The working method comprises the following steps: the method comprises the steps of firstly, uniformly paving a layer of very thin powder on a workbench, bonding a printing spray head according to part layering patterns under the control of a computer, so that the powder is bonded into a section shape, lowering the workbench by one layer thickness after one layer is finished, paving a layer of powder on the upper layer by a powder paving mechanism, and spraying and bonding the powder according to the corresponding pattern of the layer. This process is repeated until the entire three-dimensional model is created. After all the powder is bonded, the redundant powder is removed, and the required parts are obtained after the treatment such as polishing, drying and the like. 3DP can use various powder materials, such as metal powder, gypsum powder, ceramic material, polymer material and their composite powder.
At present, the traditional powder is mainly conveyed in a pneumatic mode, the pneumatic conveying is large and complex, and compressed air, an air source, an air storage pump, a dryer, an air pipeline, air separation, a fan, a control system and various valves are mainly adopted. These result in a complicated construction of the feeding equipment and are very noisy. Most importantly, the existing pneumatic powder conveying device cannot separate air from powder, so that a large amount of air and powder cannot accumulate and fly all over the sky. In addition, the filter element is easy to adhere powder, so that the filter element is blocked.
