In SLA printing technology, the photopolymer resin inside the production tank is cured with a UV laser source. With the required number of repetitions of this process, the printing is completed.
After rinsing with a solvent to remove excess resin, the object; It is kept in an ultraviolet oven to further harden the plastic.
It is a frequently preferred printing technology with parts with high accuracy and smooth surface quality. Besides, it always requires a support structure. The support structures are in the same material as the part, so that they can be removed after printing.
SLA parts can be finished to a very high standard using a variety of post-processing methods such as sanding and painting and finishing.
