Problems solved by technology

[0002] Existing light-curing 3D printers are generally equipped with only one optical machine, and its resolution is usually fixed and single, and the size of a single pixel is also constant, so this determines the printing accuracy of the printer. Therefore, the optical machine The resolution of the printer limits the printing accuracy of the printer and the surface quality of the print
At present, for variable format printing, the printing format can be changed by changing the focal length of the camera, but it cannot change the printing resolution, and it is difficult to improve the quality of 3D printing on this basis

Embodiment Construction

[0037] At present, 3D printing is well known to people, and 3D printers can realize 3D printing of workpieces, mainly through the following methods: such as figure 1 As shown in the figure, modeling is first performed by modeling software (modeling of the workpiece to be printed), and then the built 3D model is cut into layer-by-layer sections (that is, multiple slice layers are obtained by performing a slicing operation). The 3D printer 100 prints layer by layer according to the section, taking photocuring 3D printing as an example, as figure 2As shown, the printed part will be formed on the formed product table 104. After each layer of printed sheet is printed, the forming platform 104 will rise to the thickness of the next layer of slices (thickness of a new layer of printed sheet) , and then the light machine 101 projects light to the light-transmitting portion 102 at the bottom of the tray 103, and the photocurable printing material in the exposed area will polymerize an...

Abstract

The application provides a 3D printing method and device, a storage medium and a 3D printing system. The 3D printing method comprises the following steps: obtaining a plurality of slices of a workpiece model to be printed; determining control parameters corresponding to each slice, wherein the control parameters are used for controlling the printing accuracy when printing the slice, and the control parameters corresponding to at least two slices are different; and printing the slices according to the control parameters corresponding to each slice, so as to obtain the workpiece corresponding tothe workpiece model to be printed. The printing accuracy when printing the slice is controlled by determining the control parameters corresponding to each slice of the workpiece model to be printed,therefore, different parts of the workpiece can be printed with different accuracy; relatively high-accuracy printing can better reflect details; and relatively low-accuracy printing can maintain theprinting efficiency. Therefore, different parts of the workpiece can be printed with different accuracy, and therefore, the print quality can be ensured.

Description

technical field [0001] The present application relates to the field of 3D printing, in particular, to a 3D printing method, device, storage medium and 3D printing system. Background technique [0002] Existing light-curing 3D printers are generally equipped with only one optical machine, and its resolution is usually fixed and single, and the size of a single pixel is also constant, so this determines the printing accuracy of the printer. Therefore, the optical machine The resolution of the printer limits the printing accuracy of the printer and the surface quality of the print. At present, for variable format printing, the focal length of the camera can be changed to change the printing format, but it cannot change the printing resolution, and it is difficult to improve the quality of 3D printing on this basis. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a 3D printing method, device, storage medium and 3D pri...
