Automatic 3D printing device and automatic 3D printing device method

Abstract

The invention relates to an automatic 3D printing device and an automatic 3D printing device method. The device comprises an irradiation source, a bearing substrate, a resin groove and an automatic pre-correction device, wherein the irradiation source is connected with a control system of the automatic pre-correction device; the irradiation source is fixed below the bearing substrate; a light-transmitting part is arranged at a position facing the irradiation source, of the bearing substrate; the rein groove is fixed above the bearing substrate; the bearing substrate is connected with the control system of the automatic pre-correction device; an upper cantilever beam of the automatic pre-correction device is fixed to a lifting adjustment structure; a forming tray of the automatic pre-correction device is installed on the upper cantilever beam; a plurality of electric adjustment nuts of the automatic pre-correction device are arranged between the forming tray and the upper cantilever beam; and a plurality of tension and pressure sensors of the automatic pre-correction device are arranged between the forming tray and the upper cantilever beam, and installed on the upper surface of theforming tray. According to the automatic 3D printing device and the automatic 3D printing device method, automatic leveling and automatic correction for a printing starting position can be carried out before printing is started.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an automatic 3D printing device and method. Background technique [0002] 3D printing technology is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to build objects by layer-by-layer printing. At present, 3D printing technology is developing vigorously, and most of the 3D printing methods are manually operated on site: first, the preparatory work for 3D printing is carried out, and then the printing equipment performs layer-by-layer printing according to the prepared conditions. After printing, manual disassembly and printing are required. The finished model can be printed next time. The first and last process of the printing operation requires manual intervention, which is time-consuming and labor-intensive; especially after printing, if the model is not disassembled in time, the next printing cannot be perf...

AI Technical Summary

Problems solved by technology

The first and last process of the printing operation requires manual intervention, which is time-consuming and laborious; especially after printing, if the model is not disassembled in time, the next printing cannot be performed, and the efficiency is extremely low.

[0003] In addition, when using the bottom printing method, the lower surface of the forming tray must be parallel to the lower liquid surface of the printing resin in the resin tank every time before printing the workpiece model, but it is difficult to ensure that the two are consistent in the actual operation process. They are all parallel to each other; during the remote operation of 3D printing, it may happen that there is no resin in the resin tank or the amount of resin is not enough when printing starts; tight situation

All of the above situations are the reasons for the relatively low efficiency of 3D printing.
