Working with Tough 2000
Is Tough 2000 easy to machine?
Drills, taps and mills cleanly with sharp tools, high speed and light feed; keep cutters cool because the part softens above ~50 °C and edges chip if the resin is under-cured.
Can Tough 2000 be welded?
Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or a bead of the same liquid resin flashed under a 405 nm lamp.
Can Tough 2000 be formed, bent or molded?
Shape is set by printing: orient parts so hinges and snap features load across layers, use 50–100 µm layers, wash 5–10 min in IPA (avoid long soaks that swell and soften) and post-cure with heat + 405 nm UV to reach datasheet strength.

What surface finishes work on Tough 2000?
Sands and wet-polishes to a smooth surface; primer + paint or vapour-free spray finishes adhere well, but plan for post-cure shrinkage (~0.2–0.5 %) and use UV-blocking topcoats since bare parts yellow and embrittle in sunlight.
Surface treatments FabDigit runs on polymer parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

Tough 2000 — frequently asked
What is Tough 2000 used for?
Tough 2000 is typically used for snap-fit housings and clips, living hinges, functional assembly prototypes, press-fit and threaded test parts, handheld device enclosures and drop-test prototypes. In short: impact-resistant ABS-like resin.
What is the yield strength of Tough 2000?
Tough 2000 has a typical yield strength of 44 MPa (6.38 ksi) and a tensile strength of 50 MPa (7.25 ksi) — weaker than 60% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is Tough 2000 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drills, taps and mills cleanly with sharp tools, high speed and light feed; keep cutters cool because the part softens above ~50 °C and edges chip if the resin is under-cured.
Can Tough 2000 be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or a bead of the same liquid resin flashed under a 405 nm lamp.
What surface finishes work on Tough 2000?
Sands and wet-polishes to a smooth surface; primer + paint or vapour-free spray finishes adhere well, but plan for post-cure shrinkage (~0.2–0.5 %) and use UV-blocking topcoats since bare parts yellow and embrittle in sunlight.
Can Tough 2000 be formed, bent or molded?
Shape is set by printing: orient parts so hinges and snap features load across layers, use 50–100 µm layers, wash 5–10 min in IPA (avoid long soaks that swell and soften) and post-cure with heat + 405 nm UV to reach datasheet strength.
What is the maximum service temperature of Tough 2000?
Tough 2000 is rated for continuous use to about 50°C (122 °F), and briefly to 70°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Tough 2000 ABS-like and Tough 2000 GREEN?
ABS-like is the default condition — default choice for functional prototypes and enclosures that need ABS-like stiffness plus moderate impact toughness. GREEN: reference state only — properties are far below spec until UV/thermal post-cure; never use green parts for load-bearing service. Yield strength is 44 MPa in ABS-like versus 20 MPa in GREEN.
How much does Tough 2000 cost?
