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 of 155% and Ross flex fatigue of 8,000 cycles for features like snap fits and compliant mechanisms.
High Environmental Stability for Demanding Applications
The highest temperature and UV resistance of any high-compliance SLA material, with 66 °C HDT and approximately 30.4% EAB after 400 hours accelerated ageing.
Tough Parts That Don’t Deform Over Time
High creep resistance matching polypropylene, with less than 3% strain under 4 MPa load after two weeks.
*When tested under ASTM D4459 Accelerated Indoor Ageing standard.
Applications
Tough 1500 Resin V2 is ideal for resilient prototyping or simulating the toughness of polypropylene (PP).
Prototypes Requiring Toughness, Compliance, and Resilience
Simulate the toughness, compliance, and resilience of polypropylene.
Tough and Rugged Enclosures
Create functional enclosures with self-tapping screw bosses and snap fits.
Impact-Resistant Jigs and Fixtures
Produce jigs and fixtures that survive long-term use on the factory floor.
Compliant Mechanisms
Create latches, flexures, dampers, and other parts needing a combination of stiffness and ductility.

*Material properties may vary based on part geometry, print orientation, print settings, and temperature. Data was obtained from parts printed using Form 4, 100 μm, Tough 1500 V2 settings and post-cured with a Form Cure V2 for 12 minutes at 70 °C.
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.
Settings: Form Wash | Form Wash L
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.

See what our customers say about Evo3D
Real feedback from customers who have worked with Evo3D for 3D printers, materials, support and additive manufacturing solutions.
Good experience
“The order was completed but not dispatched for delivery. However, following a call with the company, they immidiately dispatched it with a discount offer for my next purchase. They had reasonable pricing and good customer service. Recommeded.”
Good team, striving to push UK Additive forward
“Olly, Martin, Jake and Martin have all been hugely supportive since our entry into larger scale 3D print last year, and continue to be so. Helpful in their initial advice, supportive since then to help us grow, and as a team they are actively pushing the limits to develop the large format in the UK. And always good to chat to as well!”
Excellent Supplier
“We have been working with Evo3D for about 6 months now and they have been an excellent resource and support to the business I work for. They have worked with us in all sorts of ways to get around any limitations and have supported our projects excellently”
