SLA works by utilizing the principles of photopolymerization.
The additive manufacturing process begins with a vat of liquid resin selectively cured by a UV light source, solidifying one layer at a time.
The build platform gradually moves, curing and fusing each layer. This precise layering process produces highly accurate, intricate parts with smooth surface finishes.

Protects SLA prints from UV exposure while enhancing visual appearance. This finish helps maintain color stability and preserves the part’s structural integrity over time.
A primer is first applied to create a smooth base, followed by a color coating. This enables detailed, high-quality surfaces and customized visual results.
Careful buffing and smoothing create a glossy, reflective surface that enhances fine details and can improve transparency.
Fine particles such as sand or glass beads remove the outer layer to create a smooth, uniform surface and eliminate support marks.

Choosing the right 3D printer for your automotive part? Here’s how to decide.
You have a CAD file and a delivery deadline. You need a part — not a printer. Whether you’re a procurement manager sourcing functional components or a mechanical engineer validating a prototype, the process question always comes up: FDM, SLA, or SLS? The right answer depends on three things: geometry complexity, surface quality required, and whether the part needs to perform under load or simply look right. This article walks through each process clearly — so you can decide with confidence and source the right part, including via MakerVerse’s instant quoting platform. The Topic in a Nutshell Process determines surface finish: FDM leaves visible layer lines; SLA delivers the smoothest finish straight off the machine; SLS produces a slightly textured surface that post-processing can refine. Complexity without support costs: SLS needs no support structures — making it the most cost-effective choice for undercuts, internal channels, and small-batch functional parts. FDM
