SLA 3D Printing in Canada

SLA was the first 3D printing technology and remains the gold standard for surface finish and feature resolution. A UV laser (or, in modern LCD machines, a high-resolution screen) cures liquid photopolymer one layer at a time, producing parts with smooth surfaces, fine details, and extremely tight feature accuracy.

Where SLA Wins

Visual prototypes and design verification. Industrial design teams use SLA to validate aesthetic and ergonomic decisions before committing to tooling.

Dental and orthodontic. Crowns, bridges, surgical guides, models, and aligner-printing patterns. Canadian dental SLA capacity is well-developed in major urban centres.

Jewelry and investment casting patterns. Castable resins burn out cleanly, leaving cavities that produce high-fidelity cast jewelry, dental, and turbine blade patterns.

Master patterns for low-volume molding. Silicone molding and short-run urethane casting use SLA-printed masters extensively.

SLA Material Categories

Standard resin — visual prototypes and design verification. Tough and durable resins — functional prototypes that must survive testing. High-temp resin — molds and patterns for short-run production. Castable resin — jewelry, dental, and investment casting patterns. Bio-compatible / dental resins — Class I medical and dental devices.

Limitations of SLA

UV degradation. Photopolymers continue to react with sunlight over time. Long-life outdoor parts should not use SLA.

Mechanical performance. Even tough resins do not match thermoplastic mechanical properties. For production functional parts, use SLS, MJF, or injection molding.

Build size. Most production SLA machines have build envelopes under 300 x 300 x 400 mm. For larger parts route to FDM or SLS.
