Stereolithography (SLA) 3D Printing Service
This technology is ideal for high-resolution finishes on medium- to large-sized parts. It is an extremely cost-effective solution for creating durable, aesthetically pleasing parts of considerable size on a tight deadline. Stereolithography (SLA) resins with extremely high heat deflection are available and are great candidates for molds or inserts.
How does the Stereolithography technology work? SLA cures photopolymer resin with an ultraviolet laser. The laser traces a shape dictated by the original file across the surface of the resin bath. The resin touched by the laser hardens, then the build platform descends in the resin bath and the process is repeated until the entire part is complete.

SLA 3D Printing Finishes
Supports are removed and minimally sanded in order to remove the support nubs left behind with some nubs remaining in hard-to-reach areas. Build lines are visually present and the parts have a granulated/gritty texture.
Supports are removed , parts are bead blasted and then sanded smooth. Build lines are somewhat present, but parts have a smooth texture. Bead blasted parts will make clear parts look frosty/cloudy.
Supports are removed and then the parts are sanded and bead blasted. Paint is applied directly to parts without a primer which means the build lines will be somewhat present through the paint.
Supports are removed and then the parts are sanded and bead blasted. A basic clear coat is applied to parts, but the build lines will still be somewhat present under the clear coat.
Supports are removed, parts are bead blasted and extensively sanded until all build lines are removed. Primer is applied before painting. Pantone color or color chip will need to be supplied to match color. Parts are smooth and build lines are completely removed. Parts look as close to production quality as possible.
Supports are removed, parts are bead blasted and extensively sanded until all build lines are removed. Multiple coats of clear are applied. Parts are smooth and build lines are completely removed. Parts are completely clear—almost glass-like.
Why Choose SLA 3D Printing?
Brands use SLA for many reasons. SLA is an excellent choice if your project requires fine features, smooth surface finishing, part precision and accuracy, isotropy, mechanical attributes, water tightness or versatility of materials.
SLA offers a combination of high-quality resolution and surface finishes at large volumes. SLA is also very effective at faithfully capturing the intricacies of even the most complex parts. Clear SLA resins can achieve colorless clarity with additional post processing to mimic clear plastics. SLA specializes in creating parts that are highly cost-intensive to produce using any other method of manufacturing, being consistently used for trade show models, aesthetic parts and snap fits/functional assemblies.
