Embodiment 1

[0023] Such as Figure 1-Figure 5 Shown is the high-efficiency 3DP powder spreading printing equipment of the present invention, which includes two or more printing platforms arranged in sequence along the X-axis direction. Each printing platform can realize the lifting action through the control of the lifting device, and each printing platform is equipped with a corresponding Rectangular printing areas, respectively 1# printing area, 2# printing area...N# printing area; each printing area shares a powder spreading device 1 and a common printing head 2 arranged above each printing platform; powder spreading device 1 The powder spreading direction is the X-axis direction which is consistent with the arrangement direction of the printing area, and the powder spreading device 1 is a two-way powder spreading device, which can reciprocate powder spreading along the X-axis direction; the printing direction of the print head 2 is the same as the powder spreading direction. The direc...

Embodiment 2

[0029] This embodiment is a method for performing 3DP high-efficiency powder-coating printing on the high-efficiency 3DP powder-coating printing device implemented above, which specifically includes the following steps:

[0030] 1) if figure 1As shown, 1#, 2#...N# printing platforms are arranged sequentially along the X-axis direction at the 3D printing production site, and 1#, 2#...N# printing areas are respectively set on each printing platform, and the position of the powder spreading device 1 is adjusted. , so that it is located at the starting position outside the 1# printing area; then adjust the position of the print head 2 so that it is located at the starting position outside the 1# printing area along the Y-axis direction;

[0031] 2) Start the powder spreading device 2, so that the powder spreading device 2 starts from the 1# printing area and spreads powder to each printing area in sequence along the powder spreading direction, until the powder spreading of the N# ...

Abstract

The invention relates to efficient 3DP powder laying printing equipment and a powder laying printing method thereof. The efficient 3DP powder laying printing equipment comprises two or more printing platforms which are sequentially arrayed in the X-axis direction. Each printing platform is correspondingly provided with a rectangular printing area. All the printing areas share one powder laying device arranged above all the printing platforms and one shared printing head. The powder laying direction of the powder laying device is an X-axis direction which is consistent with the layout directions of the printing areas. The printing direction of the printing head refers to a Y-axis direction perpendicular to the powder laying direction, and the printing head can move above all the printing areas in the X-axis direction and further return back and forth for printing in sequence. According to the efficient 3DP powder laying printing equipment and the powder laying printing method thereof, the multiple printing areas are arranged in the powder laying direction, the printing head and the powder laying device are shared, and the printing direction is arranged perpendicular to the powder laying direction; and by setting the reasonable powder laying and printing sequence, simultaneous working time of the printing head and the powder laying device is prolonged, and therefore printing efficiency is improved and printing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an efficient 3DP powder coating printing device and a powder coating printing method thereof. Background technique [0002] The 3DP molding method is a typical powder (or granular) material 3D printing technology, which was first proposed by the Massachusetts Institute of Technology in the patent US5204055A1 in 1989. The specific process of this method is to spread a layer of powder evenly on the platform first, the print head scans and sprays a liquid material in a specific area, so that the powder at the sprayed part sticks together, and then the printing platform drops the corresponding layer thickness distance, repeat the above steps until the powder laying printing work of all layers is completed. In the prior art, the powder 3D printing equipment based on the above-mentioned technology is generally characterized in that the powder spreading and printing are completed s...
