355nm UV laser light curing SLA 3D model, bringing a new revolution 3D printing is a very popular solid model manufacturing technology. In fact, it has appeared in the 1990s and is now more widely used in the direct production of some industrial products. 3D printing is the latest rapid prototyping device using technologies such as photo curing and paper lamination, and photo curing refers to lasers. The stability of the laser is very important in 3D printing technology, so it has become a key consideration for some manufacturers when purchasing 3D printing equipment.
