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.

Why Choose Tough 1500 Resin V2?
Robust, resilient and ductile material that rivals the toughness of polypropylene.
Tougher Where It Matters
10 times 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 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 4 MPa load after 2 weeks.
Applications
Tough 1500 Resin V2 is ideal for resilient prototyping or simulating the toughness of polypropylene (PP).

Post-Processing
Washing
The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through an alcohol or ether wash.
For the best surface finish, Formlabs recommends allowing parts printed in Tough 1500 Resin V2 to air dry for at least 10 minutes after washing, before handling.
Curing
Post-curing Engineering and Specialty Resins is essential for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.
