What is Stereolithography (SLA) 3D printing?
Stereolithography (SLA) is an additive manufacturing process that can 3D print parts with small features, tight tolerance requirements, and smooth surface finishes.
Stereolithography uses light to cure liquid resin into a solid object, one layer at a time. For each layer, the laser beam traces a cross-section of the part pattern on the surface of the liquid resin. Exposure to the ultraviolet laser light cures and solidifies the pattern traced on the resin and joins it to the layer below. Stereolithography requires generating supporting structures that attach the part to the elevator platform. This offers dimensional freedom and complexity. Stereolithography can be used for a wide variety of applications including functional prototyping and rapid tooling.
Parts produced through stereolithography are strong enough to be machined and can be used as master patterns for injection molding, thermoforming, blow molding, and various metal casting processes. Although SLA can produce multiple parts, it tends to be expensive due to the cost of the liquid resin and the post-processing required removing supports and smoothing the surfaces by sanding.
