The 3DP method three-dimensional printing technology was originally proposed by EmanualSachs et al, the American college of labor and technology, at the end of the 20 th century, and the forming principle thereof was: and after the designed three-dimensional model is sliced, the processed three-dimensional model is guided into a 3DP method three-dimensional printer, a spray head of the printer is controlled to spray liquid binder to a powder bed in a forming cylinder according to a certain track, the powder in the corresponding area is bound, and the powder is stacked layer by layer from bottom to top to finally obtain a printing blank. Due to the penetration of the liquid binder, additional powder is loosely bound to the surface of the printed blank, which affects the accuracy of the printed product and requires additional post-processing steps after removal. Moreover, when printing complex structural members and porous members having grooves and cavities, it is necessary to remove powder which is not sprayed onto the adhesive and is not adhered to the corresponding region during printing, so as to obtain the grooves, cavities and porous structures.
Because the strength of the three-dimensional printing blank by the 3DP method is generally low, the printing blank is easy to be broken due to improper powder removal. Blanks with complex shapes, blanks with fine internal structures are more difficult to de-dust. Currently, available 3DP method three-dimensional printing blank powder removing equipment is few, and generally is single-function semi-open type equipment, and the powder removing efficiency is low because powder is removed by adopting blowing and suction methods; the removal effect of the powder in the structure with smaller size is not good, and the powder removal is not thorough; powder dust can be generated in the operation process, which causes harm to human bodies and the environment; cleaning the equipment after the powder removal operation is completed is also a relatively expensive operation.
