Formlabs Tough 2000 Resin V1.1 is an updated engineering resin for the Form 4 that closely mimics the mechanical behavior of ABS. The V1.1 formulation has been specifically tuned for the Form 4's MSLA light engine, delivering consistent layer bonding and reliable mechanical performance across a broad range of functional applications.

This resin is engineered for parts that need to absorb impact and withstand repeated stress without cracking or shattering. It excels in functional prototype development, where parts must survive drop tests and assembly loads, as well as in snap fit and living hinge designs where toughness and controlled flexure are essential. Tough 2000 V1.1 bridges the gap between brittle standard resins and highly flexible materials, giving engineers a versatile option for iterating on production-representative parts.

Key features

• ABS-like impact resistance and toughness, suitable for demanding functional prototypes.
• Updated V1.1 formulation optimized for the Form 4's high-power light engine and faster print cycles.
• Excellent for snap fits and living hinges that require repeatable flexure without fracture.
• Good dimensional stability after post-cure, preserving part geometry under load.
• Processes cleanly in Formlabs IPA wash stations with standard post-cure settings.
• Also available in the Form 3 version (Tough 2000 V1, article 210000005900) for older printer fleets.
