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 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.
Tough 1000 Resin is a new material formulation that leverages the technology of Form 4 Series printers, with 5x higher fracture toughness, 2x higher elongation at break, and improved temperature, creep, and ageing resistance compared to Durable Resin.

Why Choose Tough 1000 Resin?
Tough 1000 Resin is a ductile, impact-resistant material with toughness that rivals high-density polyethylene (HDPE).
Durable and Ductile
Elongation at break of 180% and Gardner impact strength of 128 in-lb surpass HDPE, making it suitable for durable enclosures and components that withstand significant impact.
Environmentally Stable Parts for End-Use Applications
Improved temperature, creep, and ageing resistance compared to Durable Resin. Parts resist warping and sagging at corners and edges.
Fatigue and Wear Resistant
Hinges and functional parts can handle repeated stress and wear with a work of fracture of 3,200 J/m² and Ross flex fatigue of more than 100,000 cycles at 23 °C.
Low-Friction, Smooth Finish
Matte dark grey parts are engineered for applications that require smooth surfaces and low-friction finishes.
Applications
Tough 1000 Resin is ideal for parts that bend, compress, or deform without cracking, while maintaining long-term toughness and utility.
Impact-Resistant Jigs, Fixtures, and Parts
Create tough manufacturing aids and end-use components that resist impact and repeated use.
Squeezable Prototypes
Prototype components that need to bend, flex, compress, or deform without cracking.
Low-Friction Assemblies
Produce gears, ball joints, hinges, and other assemblies where surfaces slide without excessive abrasion or scratching.

*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 1000 Resin 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 1000 Resin to air dry for at least 30 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.

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”
