Stereolithography (SLA) is a versatile 3D printing process ideal for creating concept models, cosmetic prototypes, and complex parts with delicate geometries. It uses an additive manufacturing approach, curing thermoset resin with a UV laser to build parts layer by layer. SLA stands out for its wide material selection, ultra-high feature resolution, and the ability to deliver high-quality surface finishes for various application needs.
Design Guidelines and Capabilities
Our basic guidelines for stereolithography include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

| Tolerances | For well-designed parts, tolerances in the X/Y dimension of ±0.002 in. (0.05mm) for first inch plus 0.1% of nominal length. (0.001mm/mm), and Z dimension tolerances of ±0.005 in. for first inch plus 0.1% of nominal length, can typically be achieved. Note that tolerances may change depending on part geometry. | ||

Why Use SLA?
As an advanced additive manufacturing process, Stereolithography (SLA) excels at producing 3D printed parts with miniature features, tight dimensional tolerances, and uniformly smooth surface quality.
How Does SLA 3D Printing Work?
The SLA machine first traces support structures, then the part itself, using a UV laser on liquid thermoset resin. After each layer cures, the platform lowers, a recoating bar applies new resin, and the cycle repeats until printing finishes.
Newly printed parts are cleaned with solvents in a lab, then supports are manually removed. Parts undergo UV curing to solidify surfaces, followed by custom finishing. To avoid degradation, SLA parts should be used with minimal UV exposure and humidity.
