Formlabs Flexible 80A Resin V2 (Form 4) 1 Litre
Resilient elastomeric 3D printing material that rivals the look, feel, and function of 80A cast urethanes, TPUs, and hard rubbers.
What is Formlabs Flexible 80A V2 Resin?
Formlabs Flexible 80A Resin is an advanced, high-performance elastomeric material formulated for SLA 3D printers. Designed to simulate the flexibility and tactile feel of hard rubber or TPU, it features an 80A Shore durometer. This unique photopolymer allows engineers and designers to seamlessly 3D print soft, touchable parts that snap back into place and retain structural integrity even under repeated cycles of bending, tension, and compression.
Flexible 80A Resin V2 is a new material formulation that leverages the technology of Form 4 Series printers to deliver 2x higher tear strength, 2x higher elongation at break, 4x higher rebound, and improved aesthetics and aging compared to the previous version.
Beyond its mechanical resilience, Flexible 80A V2 Resin delivers a professional, tack-free matte finish right off the printer, ensuring your prototypes not only function like end-use products but look the part, too.
Key Features & Properties:
- High Resilience: Withstands rigorous, repeated stress cycles without tearing or suffering permanent deformation.
- Rubber-Like Flexibility: Boasts a 230% elongation at break and a perfectly balanced 80A Shore hardness.
- Exceptional Accuracy: Prints with striking precision (down to 50 microns), easily capturing fine details and complex internal geometries.
- Tack-Free Matte Finish: Mimics the aesthetic of traditional injection-molded elastomers and soft-touch plastics.
Compatible Printers:
Form 4, Form 4B, Form 4L, Form 4BL
Applications: What is it good for?
Flexible 80A Resin bridges the gap between digital design and practical, tactile functionality. Whether you are validating consumer goods or engineering custom manufacturing jigs, it is highly versatile.
Key Use Cases Include:
- Soft-Touch Prototyping: Consumer electronics, tool grips, handles, and ergonomic overmolds.
- Seals and Gaskets: Compressible, fluid-resistant components for mechanical assemblies and enclosures.
- Medical & Anatomical: Cartilage simulation and tactile pre-surgical planning models.
- Cushioning and Dampening: Impact-resistant bumpers, shock absorbers, and vibration dampeners for industrial equipment.

Note: Material properties may vary based on part geometry, print orientation, and post-curing settings. Post-curing is required to achieve the following optimal mechanical properties.
Post Processing
Washing
Use clean ≥ 90% IPA to wash Flexible 80A Resin V2. Flexible 80A Resin V2 is not compatible with Formlabs Resin Washing Solution.
For the best surface finish, Formlabs recommends allowing parts printed in Flexible 80A Resin V2 to air dry for at least 30 minutes after washing, before handling.
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.
Flexible 80A Resin V2 has a two-step curing process that ensures tack-free surfaces. Cure parts submerged in a water bath in a UV- transparent container at room temperature. After drying, cure in air at an elevated temperature.
