Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a learning algorithm-based SLA 3D printing time estimation method and system. Background technique [0002] With the development of science and technology, 3D printing technology is becoming more and more popular and widely used in many technical fields. 3D printing technology is a rapid prototyping technology. It is based on digital three-dimensional model files, and it is a technology that forms objects such as metal, plastic, and photosensitive resin through layer-by-layer printing. It belongs to additive manufacturing. Stereolithography (SLA) 3D printer is based on the principle that photosensitive resin is solidified by ultraviolet light. The computer controls the laser to scan and solidify the liquid photosensitive resin layer by layer. Obtain the physical prototype of photosensitive resin. Light-curing rapid prototyping should have the highest precision and the smoot...

Problems solved by technology

In the prior art, the printing time is usually calculated during printing. The calculation of the printing time is usually to first determine the scanning path according to the printing file, and then calculate the printing time according to the preset printing parameters. However, in the actual printing process, due to the The delay will be affected by factors such as jumping and scanning distance, time lag between electrical signals and actuators, etc. The printing time will often deviate, such as the printing deviation of each action, and then the printing time error of each layer will be superimposed , eventually the printing time of all layers will form a large deviation, which will seriously affect the printing efficiency
