UV lasers, which emit light with wavelengths between 355nm and 360nm, are commonly used for marking plastics, metals, ceramics, and glass surfaces. They are gentle on materials and do not cause much damage. With the rise of industrialization, demand for this type of marking has increased.
There is much debate over whether certain actions may cause cancer, which is another complication of life. High-quality anticancer treatments should aim to prevent and reduce cancer-causing agents in the environment, or at least minimize their negative effects as much as possible.
3D printing is a manufacturing process that involves using an ultraviolet laser, controlled by a computer, to scan liquid photosensitive resin point by point and layer by layer along a predetermined contour. This triggers photopolymerization reactions to solidify and produce solid results. The 3D printing industry has experienced tremendous growth in the past two years, and as printing processes become more mature, there are greater requirements for ultraviolet lasers. Strict parameter requirements can help address various curing-related problems, such as insufficient hardness and color differences during curing. Additionally, using air-cooled cooling makes the laser smaller and easier to integrate into the overall optical path of 3D printing.
