Product Description

Flexible 80A Resin V2 is a tear-resistant elastomer that supports repeated bending, compression, and tension. An upgrade from V1, Flexible 80A V2 has 2x higher tear strength, 2x higher elongation at break, 4x higher rebound, and an improved matte black appearance.

This material rivals the properties of urethanes, TPUs, and hard rubbers with an 80A Shore hardness. It is flexible, resilient, and recovers its shape after repeated deformation, making it an excellent choice for 3D printing parts that experience regular movement, consistent impact, or repeated user interaction.

Flexible 80A V2 is available in both 1-liter and 5-liter volumes and is compatible with several Formlabs SLA printers, including Form 4, Form 4B, Form 4L, and Form 4BL.

Possible Applications:

Engineering

• Shock absorption, cushing, and damping
• Ergonomic grips, padding, and other comfort-focused features
• Flexible parts that quickly return to their original shape after bending, tension, and/or compression
• Soft fixtures and inserts to protect sensitive components
• Functional prototypes and end-use parts that require flexibility and long-term durability

Compatible 3D Printers:

• Form 4
• Form 4B
• Form 4L
• Form 4BL

Redesigned Form 4 Resin Cartridge:

• Faster dispensing
• Fill an empty tank in 2-8 minutes with most resins
• Valve system is 5-10x faster to fill than Form 3
• Cartridge body uses less plastic, resulting in a 63% reduction in plastic waste
• Redesigned cartridge takes up 30% less shelf space
