Embodiment Construction

[0037] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0038] A digital projection surface adjustment method, such as figure 1 shown, including the following steps:

[0039] Step 101, receiving the printing format and the target format, dividing the target format into several sub-formats, the size of the sub-formats is not larger than the printing format of the projection light source;

[0040] For example, if figure 2 As shown, the printing format of the projection light source is 51.2*38.4mm, and the target printing format of the user is 80*60mm; the target printing format is divided into four sub-formats: sub-format 1, sub-format 2, sub-format 3 and sub-format 4, The size of each sub-frame is not larger than the printing frame of the projection light source.

[0041] Step 102, generating printing parameters according to the number of sub-frames and the size of the sub-frames, where the printing param...

Abstract

The invention discloses a digital projection surface adjusting method and device and a 3D printing system and method. The 3D printing system comprises a moving module, a projection light source, a forming module and a controlling module. The controlling module is used for controlling the moving module according to internally-stored printing parameters of the controlling module, so that the moving module is made to control the projection light source to move. The moving direction of the projection light source is parallel to the plane where the forming module is located. The projection light source is used for irradiating the forming module, so that raw materials on the forming module to be solidified to be an object. The digital projection surface adjusting method and device and the 3D printing system and method has the advantages that the moving module is controlled through the controlling module according to the printing parameters, so that the moving module is made to control the projection light source to move; and under the premise of guaranteeing printing precision, the printing breadth can be enlarged.

Description

technical field [0001] The invention relates to 3D printing technology, in particular to a digital projection surface 3D printing system, method, adjustment method and device. Background technique [0002] The light source is a core component of the light-curing 3D printer. At present, there are generally two types of light sources used in the light-curing 3D printer: laser point light source and digital projection surface light source. Among them, the 3D printing molding process of the laser point light source is to solidify the material into a surface bit by bit, and then solidify each surface into a 3D model. The disadvantage is that the molding speed is relatively slow. The 3D printing process of the digital projection surface light source is to directly solidify the material into the contour surface of the model, and then solidify the surface into a 3D model. [0003] The resolution of the digital projection surface light source largely determines the accuracy of the p...
