Working with Durable Resin Tough
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) |
Durable Resin Tough — frequently asked
What is Durable Resin Tough used for?
Durable Resin Tough is typically used for living hinges, snap fits and clips, PP-like functional prototypes, low-friction wear pads and bushing prototypes, press-fit enclosure lids and ball-and-socket joint prototypes. In short: wear-resistant flexible resin.
What is the yield strength of Durable Resin Tough?
Durable Resin Tough has a typical yield strength of 42 MPa (6.09 ksi) and a tensile strength of 46 MPa (6.67 ksi) — weaker than 62% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is Durable Resin Tough easy to machine?
Reasonably — machinability is rated good (60/100, better than 51% 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 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?
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.

What is the maximum service temperature of Durable Resin Tough?
Durable Resin Tough is rated for continuous use to about 55°C (131 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
