Tough 2000 Resin
A rugged SLA resin with strength and stiffness comparable to ABS, combining toughness with heat and creep resistance. Tough 2000 is the workhorse for functional prototypes and end-use parts that must resist shattering, deformation, and long-term wear.

Summary & Key Takeaways
- Simulates ABS: Strength and stiffness in the range of ABS, so ABS-intended designs can be prototyped and validated directly.
- Tough and Creep Resistant: A 1.8 GPa tensile modulus with 79% elongation at break keeps parts stable under sustained mechanical stress instead of slowly deforming.
- Warmest of the Tough Family: A 70 °C heat deflection temperature at 0.45 MPa, ahead of Tough 1500's 66 °C and Tough 1000's 44.6 °C.
- Presentation-Ready Finish: Prints dark with a matte finish, capturing fine detail without secondary finishing.

Why Choose Tough 2000 Resin?
The default choice when a part has to behave like injection-molded ABS: stiff, rugged, and stable over time.
Rugged Under Real Use
A 1.8 GPa tensile modulus and 67 MPa flexural strength paired with 79% elongation at break mean parts resist shattering and permanent deformation through drops, clamping, and repeated assembly.
Creep Resistance for Fixturing
Jigs, fixtures, and manufacturing aids hold their dimensions under sustained load and moderate heat instead of sagging, which is what separates a usable production aid from a prototype.
Machinable and Presentation Ready
Parts take drilling, tapping, and sanding without chipping, and the matte dark surface captures fine detail cleanly, so a single print serves as both a functional test part and a review model.

Source: Formlabs SLA design specifications for Form 3 / Form 4 generation printers, adapted to hold walls to a higher minimum than Formlabs' published figures. Tough 2000 is tough rather than brittle, so it tolerates thin features and sharp corners better than a glass-filled resin, but the same minimum wall applies so parts survive support removal and handling. These are general guidelines; cross-section, hole depth, and part geometry can shift the safe minimums for a specific design. Maximum build size reflects our largest-format SLA printer; actual build size depends on which machine your order routes to.
