Tough 1500 Resin V2 is a resilient material with strength, stiffness, and toughness comparable to polypropylene (PP), offering exceptional resistance to fractures, impacts, and shattering.

Create parts that balance stiffness and ductility, whether for compliant mechanisms or rugged enclosures with self-tapping screws and snap fits. Tough 1500 Resin V2 enables a wide range of applications, from functional prototypes to end-use jigs and fixtures.

Tough 1500 Resin V2 is a new material formulation that leverages the Form 4 Series to deliver 10 times higher fracture toughness than the previous version.

frequently asked questions

What is Tough 1500 Resin V2 best used for?

It’s ideal for functional prototypes, snap-fit joints, jigs, fixtures, and parts that need strength and flexibility without brittleness.

How does Tough 1500 V2 differ from the original Tough 1500 Resin?

Version 2 offers improved toughness, better impact resistance, and more consistent mechanical performance over time.

What printers are compatible with Tough 1500 Resin V2?

Tough 1500 V2 works with Form 3, Form 3+, Form 3B+, Form 4, and Form 4B SLA printers.

Does Tough 1500 Resin V2 require post-curing?

Yes. Post-curing enhances mechanical strength and stability—Formlabs recommends curing for 60 minutes at 70 °C for best results.

How does Tough 1500 Resin V2 compare to other Tough or Durable resins?

Tough 1500 V2 balances strength and flexibility between Tough 2000 (stiffer) and Durable Resin (softer), making it a versatile, all-purpose engineering resin.
