Description

TECHNICAL FIELD

[0001] The present application relates to the field of 3D printing, in particular, to a 3D printing curing device. BACKGROUND

[0002] Three-dimensional (3D) rapid prototyping, also known as additive manufacturing, is based on the principle of producing a three-dimensional object by printing or laying successive layers of material. A three-dimensional rapid prototyping device or three-dimensional printer works by converting a three-dimensional computer model of an object and producing a series of cross-sectional slices, then printing each slice on top of the other, thereby producing the final three-dimensional object. The main types of three-dimensional rapid prototyping methods include: stereolithography or light-cured layer manufacturing, selective laser melting, fused deposition modeling.

[0003] Since the existing 3D printers all have a curing process, a portion of the resin raw material will remain on the surface of the product after curing is completed, and then after manual cleaning, a second curing is usually performed, either through light curing or through high-temperature curing by heating. However, the existing 3D printers have the following disadvantages:

[0004] The post-curing device (i.e., the second curing device) adopts a fixed curing or a rotary curing manner; in the rotary curing, the light source is fixed, and the bottom is designed with a rotating disc, and the model rotates with the rotating disc during the curing process. The rotary curing has the disadvantages of inconsistent curing effect due to uneven light intensity distribution in the radial direction, and the bottom cannot be irradiated by light intensity; in the fixed curing, the light source is fixed, and the space for placing the model is also fixed, and the model is in a static state during the curing process. This scheme has the disadvantages of uneven light intensity distribution during the curing process and great difference in curing effect at different positions;

[0005] The trough of the post-curing device is fixed, and before curing, a person needs to manually place one model after another into the trough, and after curing, the person still needs to manually take out one model after another from the trough, which greatly wastes the time for pre- and post-operation;

[0006] Since the box is in a closed state during work, and the light intensity of the curing light source is high and the working time is long, heat dissipation is difficult, thereby reducing the service life of the device itself, therefore, some existing technologies often use a lower light intensity, resulting in a lower curing efficiency.
