What Is 3D Printing Photosensitive Resin?

As one of the most promising advanced manufacturing technologies at present, 3D printing has been used more and more widely in various fields by virtue of its advantages of low manufacturing cost, high production efficiency, and fast design update. Large and small companies in the industry create new value and enhance their core competitiveness.

With the continuous development and maturity of 3D printing technology, the types of 3D printing materials are becoming more and more abundant. The photosensitive resin is a widely used 3D printing material. So, what is 3D printing photosensitive resin?

The photosensitive resin is UV resin, which is generally liquid, composed of polymer monomers and prepolymers, in which a photo (ultraviolet) initiator is added, which will immediately cause a polymerization reaction under the irradiation of ultraviolet light of a certain wavelength, making the liquid photosensitive resin. Rapid curing of resin materials. The reason why 3D printing photosensitive resin materials are widely used is that it has the characteristics of fast curing speed, high curing degree, high light sensitivity, high wet strength, etc. With the support of 3D printers, it can improve the dimensional accuracy, surface quality, reliability and constancy, etc., which are especially suitable for use in precision material processing and mold manufacturing.
