Technical principle

Laser sintered 3D printers are industrial 3D printers, also known as stereolithography 3D printers, SLA 3D printers. The technical principle is that the liquid photosensitive resin is scanned by a laser of a specific wavelength, and a photosensitive reaction occurs in a scanned place to form an instant curing, which is generally a large-sized 3D printing device. Due to its high molding speed and high resolution, it can print a high-precision surface smooth hand model and gradually push the low-end FDM3D printer out of the hand model market.

3D printing material

The material used in stereolithography 3D printers is generally "photopolymer", which is composed of polymer monomer and prepolymer, generally liquid, with photoinitiator (photosensitizer), UV after a certain wavelength. After irradiation of light (for example, a wavelength of 250-300 nM), polymerization is caused to complete the curing.

SLA 3D printer production process

SLA molding technology printing process generally goes through three steps: First, the machine slices the 3D model to determine the printing path; secondly, the machine illuminates the surface of the photosensitive resin material according to the procedure, and the irradiation process is point-to-line, line-to-face, The layering is cured until the finished product appears; finally, the finished product is taken out for post-processing work such as dyeing, painting, and the like.

◆The advantages of SLA molding technology in the molding process:

1. The molding process appears early and relatively mature

2, high printing accuracy, good quality

3, processing speed is fast, the production cycle is relatively short

Stereolithography 3D printing technology is the earliest proposed and commercialized molding technology. In recent years, it has been widely used in the industry of hand model production, industrial design, mechanical production, automobile manufacturing, shoe mold industry, education, medical, consumer electronics and other industries. . At present, there are not many mature and reliable SLA 3D printer manufacturers in China. The KINGS brand is the leader in the industry. It not only supplies 3D printing equipment, but also provides specific 3D printing solutions for many industries, which improves the user's production efficiency.
