Formlabs has recently introduced Tough 1500 Resin V2, an upgraded version of their engineering-grade photopolymer designed for stereolithography (SLA) 3D printing. This new formulation offers significant enhancements over the original Tough 1500 Resin V1,
making it more suitable for demanding applications that require a balance of strength, flexibility, and durability.
Key Improvements in Tough 1500 Resin V2
Enhanced Toughness and Impact Resistance: Tough 1500 is engineered to absorb impacts better than its predecessors. This improvement makes it a preferred choice for parts that might be subject to stress, impact forces, or even repeated mechanical loading. Although exact numerical specifications (for tensile strength, flexural modulus, or elongation at break) should be referenced against Formlabs’ technical data sheets, the material is positioned to bridge the gap between standard photopolymer resins and more robust engineering plastics.
Mechanical Strength:
The resin offers a balanced combination of rigidity and ductility. This means that while the printed parts are strong and capable of sustaining load, they also exhibit a degree of flexibility that prevents sudden catastrophic failure—a particularly valuable trait when simulating injection molded parts or creating assemblies that need to endure real-world handling.
Print Process Compatibility:
Tough 1500 is optimized for use with Formlabs’ SLA (stereolithography) systems. It typically prints with a high degree of dimensional accuracy and consistency, and it is designed to be amenable to standard post-curing processes. This ensures that once printed and fully cured, the parts manifest the enhanced mechanical properties promised by the material’s formulation.
Comparative Advantages:
In comparison to the earlier “Tough” or even “Durable” resin offerings from Formlabs, Tough 1500 is targeted at applications where even greater mechanical resilience is required. Its improved performance can help reduce the risk of fracture in dynamic environments, potentially extending the lifecycle of functional prototypes.
Ideal Applications
Tough 1500 Resin V2 is particularly well-suited for:
Prototypes requiring the toughness and resilience of polypropylene.
Rugged enclosures with functional elements like snap fits and self-tapping screw bosses.
Impact-resistant jigs and fixtures for long-term use on the factory floor.
Parts that need a combination of stiffness and ductility, such as compliant mechanisms like latches, flexures, and dampers
These properties make Tough 1500 Resin V2 a versatile material for applications requiring a balance of strength, flexibility, and durability
Conclusion
Formlabs’ Tough 1500 Resin represents a significant step forward for additive manufacturing materials aimed at functional and end-use applications. Its enhanced toughness and ability to absorb impacts make it a compelling option for designers and engineers who require a material that can endure stress without sacrificing detail or print resolution.
