Abstract

The invention provides a 3D photocuring dynamic focusing self-adaption light spot printing method and equipment. The method comprises the steps that 1, three-dimensional model data of a to-be-printedarticle are built anddiscretized,so that multiple layer models are obtained; 2, light spot route planning is conducted on each model, wherein a light spot route comprises the sizes and the moving direction of light spots, and the sizes of the light spots are dynamically changed according to the area size of the layer models; and 3, according to the light spot route obtained through planning of step 2, the layer models are printed, the sizes of the light spots are dynamically adjusted through the printingequipment, and printing is conducted along the light spot route until printing is completed. Light spot route planning is conducted on each layer model, The proper light spot sizes are set for printing in all different areas in the layer models according to the shape and performance requirements; and the light spots are gradually decreased at positions with sharp corners; and on the premise that the printing precision and printing article performance are guaranteed, dynamic light spotprinting can be achieved in all directions, and the printing speed can be increased.

Description

technical field

[0001] The invention relates to a 3D photocuring dynamic focusing adaptive spot printing method. Background technique

[0002] 3D photo-curing printing technology is a rapid prototyping technology that uses laser light to irradiate photosensitive resin materials to quickly solidify liquid resin into product shapes; it is based on digital models and uses liquid photosensitive resin as material to print layer by layer. Construct objects.

[0003] In 3D photo-curing printing, before starting to "print" the object, it is necessary to obtain the three-dimensional model data of the object to be printed, and then slice the three-dimensional model to obtain the layer model of each layer that needs to be printed. Each layer of the model generates the scanning path of the ultraviolet laser by setting the printing parameters. The ultraviolet laser scans the liquid resin sequentially along the scanning path of each layer model, and the scanned resin thin layer will und...
