Formlabs® Flexible 80A, V2 | Form 4

Formlabs Flexible 80A Resin V2 brings the mechanical properties of hard rubber, TPU, and 80A cast urethane directly to your 3D printer. Ideal for creating everything from functional, tear-resistant prototypes to sleek, matte-black consumer grips and protective enclosures.

Key Capabilities:

• High Resilience: Withstands non-stop bending, compression, and stretching with instant snap-back.
• Premium Finish: Delivers a non-sticky, tack-free matte black surface texture.
• Form 4 Optimised: A next-generation formulation designed to maximize Form 4 Series performance.
• V2 Upgrades vs. Previous Generation:
  • 2x Tear Strength
  • 2x Elongation at Break
  • 4x Rebound Resiliency
  • Superior aging and visual aesthetics

Instruction: The 5L Container Requires a Resin Pump to work. 

Applications

Post-Processing 

Quick Post-Processing Guide

• Step 1: Wash (≥ 90% IPA Only) – Clean excess resin using standard IPA. Do not use Formlabs Resin Washing Solution. Let the parts air dry for a minimum of 30 minutes before handling to ensure an optimal finish.
• Step 2: Dual-Stage Cure – Post-curing completes the chemical reaction required for full material strength. To ensure a completely tack-free surface, use this two-step method:
  • Cure submerged in a water bath (using a UV-transparent container) at room temperature.
  • Dry the part, then cure in air at an elevated temperature.
