Description

Technical Field

[0001] The utility model relates to the technical field of intelligent control, and more particularly to a honeycomb matrix parallel light source component based on intelligent control. Background Art

[0002] Stereolithography is one of the earliest 3D printing technologies and is currently one of the more mature 3D printing technologies. The basic principle of this technology is to utilize the layer-by-layer solidification of materials, stacking them up to form a three-dimensional target part into several planar layers. Liquid photosensitive resin is then scanned with a beam of light of a certain wavelength, causing the scanned portion of each layer of liquid photosensitive resin to solidify and form, while areas not irradiated by the beam remain liquid. Ultimately, each layer accumulates to form the desired target part. Currently, the more common types of photocuring 3D printers include SLA, DLP, and LCD. Among them, LCD photocuring 3D printers are more commonly used due to their high precision and cost-effective equipment. However, existing LCD photocuring 3D printers always illuminate the entire screen regardless of the printing area of ​​the current layer. However, high-intensity full-screen illumination affects the service life of the LCD screen. Therefore, how to improve the service life of the LED screen is an urgent problem that technicians in this field need to solve. Utility Model Content
