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 1000 Resin (Form 4)—
Why Choose Tough 1000 Resin V2?
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, for durable enclosures and components that withstand significant impact.
Environmentally Stable Parts for End-Use Applications
Improved temperature, creep, and aging resistance compared to Durable Resin. Parts resist warping and sagging at corners and edges
Exceptional Fatigue Resistance and Toughness
Produce jigs, fixtures, and functional parts that experience repeated stress and wear with a work of fracture of 3,200 J/m2 and a Ross flex fatigue of >100,000 cycles (30 degree deflection at 1 Hz).
Low-Friction and Wear-Resistant
Comparable lubricity to Delrin (POM), for surfaces that slide against each other without abrasion or scratches. Ideal for moving assemblies such as hinges, gears, and fixtures.
Applications
Parts requiring the strength and stiffness of HDPE
Impact-resistant jigs and fixtures that survive long-term use on the factory floor
Compliant mechanisms that withstand repeated flexing
Low-friction assemblies and non-degrading surfaces (like ball joints)

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.
SETTINGS
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.
