Durable Resin Standard

Properties of the Standard condition, compared with the other Durable Resin grades.

Pick for living hinges, snap fits, low-friction bushings and squeeze/press parts where high elongation matters more than stiffness.

What is Durable Resin Standard?

Durable Resin Standard is Durable Resin in the Standard grade — pick for living hinges, snap fits, low-friction bushings and squeeze/press parts where high elongation matters more than stiffness.

Chemical Resistance SummaryGood against water, dilute acids/bases, oils and greases; low friction and wear-resistant in dry sliding. Attacked/softened by ketones, esters, chlorinated solvents, strong alcohols (IPA soak >20 min softens parts) and hot water; continued UV exposure causes yellowing and loss of elongation.

Sustainability3

Producing a kilogram of Durable Resin Standard takes about 130 MJ of energy and emits 5.5 kg of CO₂ — more than 78% of polymer grades. Typical recycled content is 0%.

Working with Durable Resin Standard

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 %)

Durable Resin Standard — frequently asked

What is Durable Resin Standard used for?

Durable Resin Standard 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 Standard?

Durable Resin Standard has a typical yield strength of 22 MPa (3.19 ksi) and a tensile strength of 28 MPa (4.06 ksi) — weaker than 83% of polymer grades. Strength varies by condition: see the 4 listed tempers.

Is Durable Resin Standard easy to machine?

Reasonably — machinability is rated good (55/100, worse than 63% 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 Standard 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 Standard?

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.

Can Durable Resin Standard 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 is the maximum service temperature of Durable Resin Standard?

Durable Resin Standard is rated for continuous use to about 40°C (104 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between Durable Resin Standard and Durable Resin Tough?

Standard is the default condition — pick for living hinges, snap fits, low-friction bushings and squeeze/press parts where high elongation matters more than stiffness. Tough: pick when the part needs both stiffness and impact resistance — housings, jigs, brackets, threaded/assembled prototypes replacing ABS. Yield strength is 22 MPa in Standard versus 42 MPa in Tough.
