High-Resolution 3D Printing
The perfect fit for accurate, high-resolution finished parts
Stereolithography 3D printing is ideal for medium or large parts that require a "show model" look, or in instances with an emphasis on aesthetics.
This process is appealing not only because of the quality surface finish and clear parts, but also as a cost-effective option for accurate parts.
It is worth mentioning, however, that the material may degrade with UV or humidity exposure, and the parts tend to be fragile or have structural instability.
How It Works
An overview of the SLA 3D printing process
Stereolithography (SLA) is an epoxy-based photopolymer system that utilizes lasers to cure the resin on the cross-sectional area of the part. It begins with a recoating bar that applies a thin layer of resin, then an ultraviolet laser creates an image of the part on that resin. After one layer, this process is repeated until the build is complete.
Once the build is complete, the parts are removed and put into a solvent to remove excess resin. The SLA process uses supports of the same material as the part itself, which have to be manually removed. From there, the parts go through a curing cycle in a UV curing machine.
