Photocuring 3D printing equipment and photocuring printing method

Abstract

The invention provides photocuring 3D printing equipment and a photocuring printing method, and relates to the technical field of 3D printing. The photocuring 3D printing equipment comprises a frame, a printing head, a driving device, a supply device and a control device; the supply device is connected with the printing head; the driving device is arranged on the frame, and can drive the printing head to move; the control device can control the driving device and the supply device to work; the printing head comprises a printing head body and a photocuring element; the photocuring element and the printing head body are arranged correspondingly, so that a printing material can be quickly solidified under the effect of the photocuring element; the supply device comprises a pressure container, a supply adjusting structure and an output guide pipe; the pressure container and the printing head body are connected through the output guide pipe; and the supply adjusting structure is arranged on the output guide pipe for adjusting the flow. The photocuring printing method is based on the photocuring 3D printing equipment, and can relieve the problems of complicated structure, high design difficulty, supply discontinuation and low printing efficiency caused by higher printing head temperature.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a light-curing 3D printing device and a light-curing printing method. Background technique [0002] The FDM hot melt deposition 3D printer can heat the printing material, and then extrude it to make the printing material into a semi-molten filament, which is deposited on a layer-by-layer basis, and the model is directly constructed from the 3D CAD data. However, this type of 3D printer has the following disadvantages: the printing material needs to be heated during the printing process, which leads to a high temperature at the print head and a complicated structure. On the one hand, higher requirements are placed on the design of the print head. On the other hand, during the printing process, the printing material will be softened ahead of time due to the higher temperature print head, which reduces the feeding pressure, so that the printing process is prone to material break...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a light-curing 3D printing device and a light-curing printing method to alleviate the high temperature of the print head in the printing process of the 3D printer in the prior art, improve the design requirements of the print head, and make the printing material Pre-softening leads to insufficient feeding pressure, which is prone to material breakage and reduces printing efficiency
