Stereolithography printers (SLA) are precision and accuracy. A thin layer of UV-curable photopolymer resin is applied to a build table, then a UV laser is used to trace a pattern based on a CAD program. Afterwards, it’s lowered to cover the table with resin and the process is repeated until the desired three-dimensional shape is produced. This process allows for the smoothest surface finish of any additive manufacturing process. Stereolithography printers offer the most accurate type of fit/form prototype and is the preferred choice for designer models, engineering verification, and master patterns for silicone rubber molds.
Stereolithography printers (SLA) achieve a level of quality that permits immensely accurate casting patterns for a number of areas that require precision above all else. SLA printing is not only versatile, but saves money and time. Stereolithography printing is quite fast and stays true to the design. SLA doesn’t require slow and expensive retooling if there happens to be design flaws and can be adjusted before it goes into production. No process handles a wider range of applications and rapid manufacturing demands.
Try before you buy!
If you’re considering a purchase of a 3D printer you may want to test your part on one or multiple machines to determine the best investment.
