Other Tough Resin grades and fills
Tough Resin is also supplied in 6 other conditions. The full side-by-side table is on the Tough Resin overview.
- ABS-likeDefaultDefault choice for functional prototypes and enclosures that need ABS-like stiffness plus moderate impact toughness.50 MPa tensile
- GF-filledFilled tough resin for stiff, creep-resistant, higher-temperature tooling — accept brittleness and abrasive post-processing.70 MPa tensile
- Rigid-ProUse when dimensional stability under load and a higher HDT matter more than elongation (jigs, moulds, precise fixtures).61 MPa tensile
- Tough-2000Best all-round substitute for injection-moulded ABS when both stiffness and elongation are needed in one part.46 MPa tensile
- Tough-1500Pick when the part must flex and snap back repeatedly (living hinges, snap-fits, press-fit clips) rather than be stiff.33 MPa tensile
- Durable-PPChoose for wear surfaces, bearings, squeeze bottles and low-friction assemblies where polypropylene-like compliance beats stiffness.32 MPa tensile
Working with Tough Resin Tough-1500
Is Tough Resin 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 Resin 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 Resin 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 Resin?
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.
Tough Resin chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| urethane acrylate / epoxy acrylate oligotoughening backbone; determines elongation and impact | 30 – 60 | 45 |

Tough Resin Tough-1500 — frequently asked
What is Tough Resin Tough-1500 used for?
Tough Resin Tough-1500 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 Resin Tough-1500?
Tough Resin Tough-1500 has a typical yield strength of 44 MPa (6.38 ksi) and a tensile strength of 33 MPa (4.79 ksi) — weaker than 64% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is Tough Resin Tough-1500 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 63% 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 Resin Tough-1500 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 Resin Tough-1500?
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.

What is the maximum service temperature of Tough Resin Tough-1500?
Tough Resin Tough-1500 is rated for continuous use to about 45°C (113 °F), and briefly to 70°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
