Tough 1500 V2 Resin

Formlabs Tough 1500 (V2) is a stiff but compliant material with toughness that rivals polypropylene. It offers exceptional resistance to fractures, impacts, and shattering.
With this new resin formulation, you can create parts that balance stiffness and ductility, whether for compliant mechanisms like rugged enclosures with self-tapping
screws and snap fits.
Tough 1500 Resin V2 leverages the Form 4 Series to deliver 10 times higher fracture
toughness than the previous version.

NOTE: The 5L container requires a Resin Pump to work.

Highlight and Benefits

• Tougher Where It Matters
  10 X higher work of fracture, so parts don’t fail when drilled, tapped, or cracked. Three times higher Gardner impact strength for thin walls that don’t shatter.
• Ductile and Resilient for Long-Lasting Compliant Parts
  Extremely high elongation at break (155%) and Ross flex fatigue (8,000 cycles) for features like snap fits and compliant mechanisms.
• High Environmental Stability for Demanding Applications
  The highest temperature and UV resistance (66°C HDT and –30.4% EAB* after 400 hours of accelerated aging) of any high-compliance (>100% EAB) SLA material.
  *When tested under ASTM D4459 Accelerated indoor aging standard.
• Tough Parts That Don’t Deform Over Time
  High creep resistance matching polypropylene, with less than 3% strain under 7 MPa load after 2 weeks.
