Three-dimensional light curing molding (SLA) is usually the use of photosensitive resin as a raw material, the use of liquid photosensitive resin under the UV laser light will cure quickly. The photosensitive resin is generally liquid, and it causes condensation reaction immediately under the light of a certain wavelength of ultraviolet light (250 nm ~ 400 nm) and cures. The printer consumables that can be used at this stage of SLA technology are photosensitive resins, which are key for making a variety of abrasive tools, solid models, etc. It is also possible to add other ingredients to the raw material and replace the wax mold in the investment mold precision casting with the SLA mold.

Before printing, the resin tank is filled with liquid photosensitive resin, and the lifting table is at the height of the cross section thickness under the liquid level. After focusing, the laser carries out the scanner on the edge liquid level under the control of the computer system, and the resin in the area of the scanner is cured, so as to obtain a layer of resin sheet in this section. The lifting table reduces a thickness spacing, the liquid resin is exposed to the light source again, and the scanner is cured again, and so on, until all the goods are formed; The lifting platform lifts the surface of the liquid resin, takes off the product workpiece, carries out the corresponding post-treatment process, and obtains the required finished product according to the operation of strong light, electroplating process, spraying or coloring.
