Working with Durable Resin Tough-1500
Is Durable Resin easy to machine?
Machinable with sharp tools, high speed and low feed, but the soft matrix smears — prefer drilling/reaming to milling and avoid coolant soak.
Can Durable Resin be welded?
Thermoset — cannot be heat welded; join with cyanoacrylate, UV-cure acrylate or two-part epoxy after light abrasion.
Can Durable Resin be formed, bent or molded?
Print at 50–100 µm layers, orient living hinges so bending is across layers, then wash briefly in IPA (<10–15 min) and heat post-cure (typically 60–70 °C UV) to reach datasheet properties.
What surface finishes work on Durable Resin?
Sands and vapor-free polishes to a satin finish; primer + flexible paint or dyeing works, but keep parts out of sunlight or clear-coat with a UV-blocking topcoat.
Durable 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 / aliphatic acrylate oflexible backbone giving the PP-like high elongation | 40 – 70 | 55 |
| photoinitiator (acylphosphine oxide type | 0.5 – 3 | 1.5 |
| pigments, UV blockers, additives | 0.1 – 3 | 1 |
| acrylate & methacrylate reactive monomercontrols viscosity, crosslink density and modulus | ≥ 25 (balance) |

What is the yield strength of Durable Resin Tough-1500?
Durable Resin Tough-1500 has a typical yield strength of 22 MPa (3.19 ksi) and a tensile strength of 33 MPa (4.79 ksi) — weaker than 78% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is Durable Resin Tough-1500 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Machinable with sharp tools, high speed and low feed, but the soft matrix smears — prefer drilling/reaming to milling and avoid coolant soak.
Can Durable Resin Tough-1500 be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — cannot be heat welded; join with cyanoacrylate, UV-cure acrylate or two-part epoxy after light abrasion.
What surface finishes work on Durable Resin Tough-1500?
Sands and vapor-free polishes to a satin finish; primer + flexible paint or dyeing works, but keep parts out of sunlight or clear-coat with a UV-blocking topcoat.
