What is Formlabs Tough 1500 Resin? 

Formlabs Tough 1500 resin is a resilient SLA material that balances stiffness with ductility. It offers strong resistance to fracture and impact, with a post-cured elongation at break of 155%. Parts can flex while retaining the structure needed for functional features. 

Formlabs Tough 1500 Resin Overview

Applications

Formlabs Tough 1500 resin is well suited to functional parts that need to flex while retaining their shape and structure. Its toughness and ductility make it useful for snap-fit enclosures, latches, flexures, dampers, and self-tapping screw bosses. It also suits jigs and fixtures exposed to impacts and repeated handling.

Key Product Benefits

  • High toughness and impact resistance
  • 155% elongation at break after post-curing

Tolerances

Dimensional accuracy depends on part size, geometry, orientation, supports, and post-processing. Call out critical fits and dimensions so we can review them before manufacture. Material-specific tolerances should be confirmed during quoting.
