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).
Prototypes requiring the toughness, compliance and resilience of polypropylene.
Tough and rugged enclosures with functional elements like self-tapping screw bosses and snap fits.
Impact resistant jigs and fixtures that survive long term use on the factory floor.
Parts that need a combination of stiffness and ductility to create compliant mechanisms like latches, flexures, and dampers.

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 a solvent wash.
Use clean ≥ 90% IPA, or use Formlabs Resin Washing Solution.
For the best surface finish, Formlabs recommends allowing parts printed in Alpha Resins to air dry for at least 30 minutes after washing, before handling.
SETTINGS
Form Studio Wash+Cure | Form Wash | Form Wash L
Curing
Post-curing Alpha Resins is optional, but recommended, 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.

Next-Generation Tough Resins That Rival Thermoplastics
Tough 1000 Resin is a ductile, impact-resistant material with comparable strength, stiffness, and toughness to high-density polyethylene (HDPE), designed with exceptional wear and fatigue resistance for long-term toughness and utility.
The 180% elongation at break (EAB) and Gardner impact strength of 128 in-lb surpass HDPE, making it ideal for parts that bend, compress, or deform without cracking. Hinges and functional parts can handle repeated stress and wear with a work of fracture of 3,200 J/m2 and a Ross flex fatigue of >100,000 cycles (at 23 °C). With a matte, dark grey color, Tough 1000 Resin is engineered for applications that require smooth surfaces and low-friction finishes.
Tough 1000 Resin is a new material formulation that leverages the technology of Form 4 Series printers, with 5x higher fracture toughness, 2x higher EAB, and improved temperature, creep, and aging resistance compared to Durable Resin.
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.
