Mobile 3D printer and printing method thereof

Abstract

The invention discloses a mobile 3D printer and a printing method thereof. The 3D printer comprises a machine base, an exposure mechanism, a printing mechanism, a solution containing mechanism and a control mechanism, wherein the exposure mechanism, the printing mechanism, the solution containing mechanism and the control mechanism are arranged on the machine base. The solution containing mechanism comprises a material tank used for containing a printing solution, and a drive assembly for driving the material tank to slide. A plurality of equal-width transparent lines are arranged at the bottom of the material tank at coincident intervals. A non-transparent line is arranged between every two adjacent transparent lines, wherein the width of the transparent lines is larger than that of the non-transparent lines, and a height difference is reserved between the transparent lines and the non-transparent lines. According to the mobile 3D printer and the printing method thereof, as the transparent lines and the non-transparent lines are arranged alternately, the curing time can be significantly shortened; and due to the fact that the height difference is reserved between the transparent lines and the non-transparent lines, a printing platform can be quickly separated from the bottom of the material tank, and thus quick printing is achieved.

Description

technical field [0001] The invention relates to a mobile 3D printer and a printing method thereof, belonging to the field of 3D printing. Background technique [0002] A 3D printer is a machine that adopts cumulative manufacturing technology (that is, rapid prototyping technology). Its principle is to put data and raw materials into the 3D printer, and the machine builds products layer by layer according to the program. At present, when 3D printers expose and cure, they all use the whole layer to cure in one piece. When the curing area is large, the curing time is longer, which greatly affects the printing speed; For quick detachment, the oblique pull-out type (such as the oblique pull-out component described in the patent "a 3D printing device and its printing method" with the publication number CN104309128A) or the rotary material tank is generally used. The former structure is more complicated and the detachment time Long, the latter is only suitable for some printing so...

AI Technical Summary

Problems solved by technology

At present, when 3D printers expose and cure, they all use the whole layer to cure in one piece. When the curing area is large, the curing time will be longer, which greatly affects the printing speed; For fast detachment, the oblique pull-out type (such as the oblique pull-out assembly described in the patent "A 3D Printing Device and Its Printing Method" with the publication number CN104309128A) or the rotary material tank is generally used. Long, the latter is only suitable for some printing solutions with higher viscosity
