Formlabs Flexible 80A Resin (Form 4) 1 L RS-C2-FL80-11

Formlabs Flexible 80A Resin (Form 4) 1 L

Flexible 80A Resin is a stiff, soft-touch, translucent elastomer with an 80A Shore durometer, ideal for prototyping rubber-like parts with the flexibility of harder rubber or TPU. This material allows for the creation of parts that can withstand bending, flexing, and compression, even through repeated cycles.

This 1-litre cartridge is optimised for the Form 4 ecosystem, providing a high-performance solution for engineering and product design. It enables you to produce silicone, urethane, and rubber-like parts in-house in a matter of hours, effectively replacing expensive outsourcing and moulding processes.

Why choose Flexible 80A Resin?

Flexible 80A Resin combines superior material properties with the benefits of 3D printing to create functional, durable elastomeric parts.

• Elastomeric performance: leverage bendable parts that return to their original shape slowly after deformation.
• Soft and strong: stretch and compress parts through repeated cycles without cracking or loss of integrity.
• Transparent finish: create clear objects that provide visibility into the model, ideal for internal feature validation.
• Durable testing: support user testing with prototypes that look and feel like end-use products.
• Injection-moulded quality: achieve a professional surface finish that rivals traditional manufacturing methods.

Applications for Flexible 80A Resin:

Flexible 80A Resin is an ideal alternative to mould making for developing hard, flexible prototypes across various industries.

• Consumer goods: handles, grips, and ergonomic overmoulds.
• Industrial components: seals, gaskets, masks, and vibration dampeners.
• Protection and damping: cushioning, shock absorption, and impact-resistant parts.
• Anatomical models: realistic representations of cartilage, tendons, and ligament anatomy for medical education.

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.
