SLA (Stereolithography) technology (also known as light curing rapid prototyping technology) is based on the principle of liquid photosensitive resin. The liquid material can be rapidly changed under the irradiation of a certain wavelength and intensity of ultraviolet light (such as =325nm), and the molecular weight of the liquid can be changed from liquid to solid. Its core technology is computer technology and material technology. Laser forming technology has abandoned the traditional machining method, according to the geometry information of the parts produced by CAD, the 3D numerical

 control forming system is controlled by the laser beam.

SLS the main materials used in the actual production process include: nylon 11, nylon 12, ceramic, wax and the material is modified according to differen

t requirements. Such as adding aluminum powder to make the material have a certain metal and effect; the addition of fiber material to increase the

 hardness of the material, etc.
