Benefits of SLA (Stereolithography) 3D Printing:
- High Precision & Accuracy – SLA can achieve tight tolerances (±0.1% accuracy) and fine details down to 0.006 inches (0.15 mm).
- Smooth Surface Finish – Produces parts with a near-injection-molded quality, reducing the need for extensive post-processing.
- Wide Material Selection – Compatible with engineering-grade resins, including clear, flexible, and high-temperature-resistant materials.
- Thin Wall Capabilities – Enables delicate, intricate geometries with wall thicknesses as low as 0.5 mm.
- Functional Prototyping & End-Use Parts – Ideal for concept models, fluid flow analysis, investment casting patterns, and medical devices.
- Watertight & Transparent Parts – Certain resins, such as Somos® WaterShed XC 11122, provide moisture resistance and optical clarity.
- Scalability & Repeatability – High dimensional stability allows for consistent batch production with reliable mechanical properties.
- Fast Turnaround – SLA enables rapid prototyping and production, reducing lead times for product development.
- Customizable Post-Processing – Supports sanding, painting, vapor smoothing, and dyeing for enhanced aesthetics and functionality.
- Supports Complex Geometries – SLA’s layer-by-layer approach enables intricate designs that traditional manufacturing cannot achieve.
