Large-scale powder bed spraying liquid bonded type three-dimensional (3D) printer

Abstract

The invention provides a large-scale powder bed spraying liquid bonded type three-dimensional (3D) printer which comprises a movable powder bed, a double-gantry rack, an X-axis movement mechanism, a Y-axis movement mechanism, a Z-axis movement mechanism, a powder laying device and an adhesion promoter spraying and dropping device. The X-axis movement mechanism, the Y-axis movement mechanism and the Z-axis movement mechanism are perpendicular to one another; the Y-axis movement mechanism is connected with the double-gantry rack and the Z-axis movement mechanism; the adhesion promoter spraying and dropping device and the X-axis movement mechanism are connected and arranged on the side surface of the powder laying device; the powder laying device and the Z-axis movement mechanism are connected; and a powder bed drive mechanism drives the powder bed to move in a reciprocating way so as to expand a printing area. The large-scale powder bed spraying liquid bonded type 3D printer provided bythe invention has the beneficial effects that a powder material and an adhesion agent are mixed so as to be laid on the powder bed, the adhesion promoter is then sprayed through the adhesion promoterspraying and dropping device and is reacted with the adhesion agent so as to be cured and formed, and a 3D entity is finally printed, so that the size range of a printable model is large, the printingefficiency is high, the cost is low, and the large-scale powder bed spraying liquid bonded type 3D printer is particularly suitable for quickly manufacturing a large-scale industrial model.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a large powder bed spray-liquid bonding 3D printer. Background technique [0002] With the continuous development of 3D printing technology, various forms of 3D printing equipment continue to appear. Most of these 3D printing devices are desktop-level and can only print models of small size. Moreover, the efficiency of 3D printers is low, and printing takes a long time. Printing materials are expensive. Therefore, there is an urgent need to develop a 3D printing device for large-scale three-dimensional models with high printing efficiency to meet people's printing needs for large-scale models. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a large powder bed spray liquid bonding 3D printer, which can quickly and efficiently complete the 3D printing of large 3D models. [0004] An embodiment of the present i...
