SIRAYA TECH BLU - Tough Resin

Siraya Tech's Blu Tough resin is an engineering-grade UV resin designed for strong, durable, and precise parts. It combines high hardness with true impact resistance, making prints feel more like injection-molded plastic than standard resin. Blu is also known for its low shrinkage and clean detail, making it a reliable choice for functional prototypes, tooling, jigs, and mechanical parts. The Blu series is available in several colors/variants, all built on the same durable, high-resolution material platform.

Main features

• Tough, engineering-grade resin for functional parts
• High hardness with strong impact resistance
• Low shrinkage for precise, dimensionally stable prints
• High detail and smooth surface finish
• 405 nm resin for compatible MSLA/LCD and DLP/SLA printers
• ISO 10993-10 certification for skin-safe external applications (when appropriately post-processed)

Durable engineering resin for functional prints

Blu Tough resin is formulated to withstand real-world mechanical use. Prints are hard and rigid, yet durable enough to resist cracking under stress. This makes the material suitable for functional prototypes, brackets, fasteners, and final components.

Precision with low shrinkage

The Blu platform is designed to ensure dimensional stability. Low shrinkage helps components maintain tight tolerances, especially in mechanical assemblies where fit and alignment are critical.

Clean surfaces and high detail

It prints in high-resolution blue with a smooth finish, making it a good option for components requiring both durability and visual quality. It also resists primer and paint well, for a clean final look.

Printer Compatibility and Management

The resin is optimized for 405nm MSLA/LCD printers and works with compatible DLP/SLA machines, where exposure can be controlled. For best results, use a printer profile from your slicer and maintain a stable resin temperature during printing.

Post-processing and usage notes

Wash prints thoroughly and cure fully for maximum strength. For biocompatible applications, follow the post-processing steps recommended by Siraya Tech. Store the resin sealed and away from direct light.
