Problems solved by technology

[0003] When DLP photo-curing printers print complex structures, the exposure time and peeling speed of each layer are usually fixed, but some layers are inherently cross-linked and stable, and the exposure time does not need to be too long. If the exposure time is unified by layer, the total printing If the time is too long, it will affect the printing efficiency

Abstract

The invention discloses a printing method of a DLP photocuring printer. The printing method comprises the following steps that 1, a digital 3D model of a to-be-printed object is established; 2, the digital 3D model is subjected to slicing treatment, and multiple layers of model slices are obtained, wherein the number of the model slices is n; and 3, printing is started from the bottom end to the top end of the digital 3D model from the first layer according to the model slices, wherein the number of the current printing layers is m, the exposure time is h, and h is 1s. According to the printing method, through a digital 3D model processing system, during specific using, the sectional area of the current printing model slice and the sectional area of the upper layer of model slice can be compared through a sectional area comparison unit in the digital 3D model processing system, if the sectional area of the current printing model slice is smaller than the sectional area of the upper layer of model slice, the cross-linked structure of the two layers of slices is relatively stable, thus, the exposure time can be properly shortened, the printing time of a complex model is greatly shortened, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a printing method and system for a DLP light-curing printer. Background technique [0002] The working principle of DLP (Digital Light Processing) light-curing 3D printer is to use DLP technology. The light source is imaged by a projector. The light source solidifies the liquid photosensitive resin layer by layer, and prints out a three-dimensional object with a higher resolution. Its resolution exceeds that of a typical FDM ( Fusion deposition manufacturing) type 3D printers. [0003] When DLP photo-curing printers print complex structures, the exposure time and peeling speed of each layer are usually fixed, but some layers are inherently cross-linked and stable, and the exposure time does not need to be too long. If the exposure time is unified by layer, the total printing If the time is too long, the printing efficiency will be affected. Contents of the invention [0004]...
