Formlabs Elastic 50A Resin (Form 4) 1 L RS-C2-ELCL-02

Formlabs Elastic 50A Resin v2 (Form 4) 1 L

Elastic 50A Resin v2 is a soft, translucent elastomer designed for prototyping parts normally produced with silicone or soft rubbers. This 50A Shore durometer material allows for the creation of parts that can bend, stretch, and compress repeatedly without tearing, quickly returning to their original shape.

This 1-litre cartridge is optimised for the Form 4 ecosystem, providing a high-performance solution for engineering and product design. Its elastomeric properties and high energy return make it an excellent choice for functional prototypes that require a specific "feel" and durable performance.

Why choose Elastic 50A Resin v2?

Elastic 50A Resin v2 is an elastomeric material with high elongation and high energy return. Parts are highly elastic, yet strong enough not to tear during printing.

• Fast springback: parts resume their normal shape quickly after being bent, stretched, or compressed.
• High elongation: achieve up to 160% elongation at break, providing the flexibility needed for rugged testing.
• Translucent finish: the clear appearance provides visibility into models, making it ideal for complex assemblies.
• Durable and strong: engineered to withstand multiple cycles of use without tearing during or after the printing process.
• Moulded feel: produce parts that look and feel like injection-moulded silicone, perfect for consumer product validation.

Applications for Elastic 50A Resin v2:

Elastic 50A Resin v2 is ideal for developing soft, flexible prototypes normally produced with silicone.

• Wearables: prototypes for straps, bands, and ergonomic consumer products.
• User interfaces: compressible buttons and soft-touch gaskets.
• Protective components: stretchable enclosures, casings, and impact-dampening parts.
• Robotics: compliant features, grippers, and flexible joints.
• Medical models: soft tissue anatomy for surgical simulation and educational reference.

Post-processing

Washing

The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through an alcohol or ether wash.

Curing

Post-curing engineering and specialty resins is essential for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.

Note: Only compatible with the Formlabs Form 4 series resin printer.
