QTS ENGR Strong 405nm UV Resin (1kg) - High Hardness, Impact Resistant Engineering Grade
QTS ENGR Strong is an all-purpose engineering-grade 405nm UV resin designed for functional prototypes, jigs, and fixtures. It delivers a powerful combination of high hardness (Shore 85D), superior tensile strength (57.21 MPa), and excellent impact resistance (36 J/m). This formula provides ABS-like durability and precision, ensuring your functional parts can withstand real-world stress and repeated use. Available in White and Grey.
QTS ENGR Strong UV Resin
Industrial-Grade Strength & High Impact Resistance for Functional Engineering
When your project demands more than just aesthetics, QTS ENGR Strong delivers the mechanical performance required for real-world engineering. Engineered in Taiwan, this high-hardness resin (Shore 85D) combines a formidable tensile strength of 57.21 MPa with superior impact resistance. It is the definitive choice for functional prototypes, mechanical assemblies, and industrial jigs that must withstand rigorous testing and daily use.
Key Advantages
- ▶ Exceptional Tensile Strength (57.21 MPa): Provides the structural integrity needed for load-bearing parts and functional mechanical components.
- ▶ High Impact Resistance (36 J/m): Unlike standard brittle resins, ENGR Strong is formulated to absorb energy, making it resilient against drops and mechanical shocks.
- ▶ Superior Hardness (Shore 85D): Delivers a tough, scratch-resistant surface that maintains tight tolerances even under mechanical friction.
- ▶ Excellent Dimensional Stability: Low shrinkage ensures that complex assemblies fit together perfectly every time.
Why QTS ENGR Strong Outperforms Competitors?
Most "tough" resins on the market sacrifice hardness for flexibility, resulting in parts that deform under load. QTS ENGR Strong utilizes an advanced polymer matrix developed in Taiwan that achieves a rare balance: High Rigidity + High Impact Strength. With a tensile modulus of 2750 MPa, it provides the stiffness required for engineering applications while maintaining a 23% elongation at break to prevent catastrophic failure.
Applications & Use Cases
- Functional Prototypes: Test fit, form, and function with parts that mimic injection-molded plastics.
- Jigs & Fixtures: Create durable manufacturing aids that can withstand repeated use on the factory floor.
- Mechanical Assemblies: Ideal for gears, housings, and snap-fit components.
- End-Use Parts: Suitable for low-volume production of industrial components.

Frequently Asked Questions (FAQ)
Q: Is this resin suitable for outdoor use? A: While it has excellent mechanical properties, we recommend applying a UV-resistant clear coat for long-term outdoor exposure to maintain its properties.
Q: Can I tap threads into parts printed with ENGR Strong? A: Yes! Thanks to its high hardness and tensile strength, this resin holds threads exceptionally well for mechanical fastening.
