Problems solved by technology

When the 3D printing device with this structure is solidified, because there is no obstruction on the upper surface of the solidified layer, it is easy to have a bulge in the middle due to the surface tension of the solidified layer, which in turn affects the printing quality of the 3D object.

Abstract

The invention discloses a slide liquid containing mechanism for a 3D printing device and a printing method thereof. The slide liquid containing mechanism comprises a mounting plate fixedly mounted in a 3D printing device box, wherein a guide rail is arranged on the mounting plate; a mobile bracket is movably mounted on the guide rail through a slide block; a resin frame for containing printing solution is mounted on the mobile bracket; bracket motors are respectively arranged at the two ends of the guide rail, and are respectively connected with the two ends of the mobile bracket through connecting bars; the bracket motors drive the connecting bars to drive the mobile bracket and the resin frame to horizontally move along the guide rail; a transparent baseplate is arranged at the bottom of the resin frame; the mounting plate and the mobile bracket are both provided with windows; and the windows are respectively a mounting plate window and a mobile bracket window, wherein the mounting plate window and the mobile bracket window face a printing platform of the 3D printing device. A 3D printing device employing the slide liquid containing mechanism of such a structure has the characteristics of quick printing speed and high printing precision.

Description

technical field [0001] The invention relates to a sliding liquid holding mechanism for a 3D printing device and a printing method thereof, belonging to the technical field of printing equipment. Background technique [0002] A 3D printing device, also known as a three-dimensional printer, is a machine that uses cumulative manufacturing technology (that is, rapid prototyping technology). Its principle is to put data and raw materials into a 3D printer, and the machine builds products layer by layer according to the program. At present, the 3D printing device is more common to use SLA three-dimensional printing (also known as three-dimensional lithography, optical modeling), but SLA three-dimensional printing uses a laser head, and only one laser point is used for forming. Line, line to surface, the printing speed is slow; and the SLA three-dimensional printing system is expensive, the use and maintenance costs are too high, and the printing accuracy is low; although there are...
