Durable Resin vs Formlabs Tough 2000

Polymer · grade comparison

Durable Resin and Tough 2000 are both polymer grades, both engineering plastic. Tough 2000 is the stronger of the two: yield strength 44 MPa (6.38 ksi) against 22 MPa (3.19 ksi) for Durable Resin, about 100% more; tensile strength follows at 50 MPa (7.25 ksi) vs 28 MPa (4.06 ksi). In exchange, Durable Resin is the more ductile: elongation 55% versus 22% for Tough 2000, and Tough 2000 is harder (80 Shore D vs 70 Shore D). Tough 2000 is stiffer (2.4 GPa vs 1 GPa) and Tough 2000 runs hotter in service (50°C vs 40°C continuous).

Durable ResinChoose it when the part is bent, formed or impact-loaded.

Tough 2000Choose it when strength drives the design, or when the part sees heat.

Durable Resin vs Tough 2000 — frequently asked

Is Tough 2000 stronger than Durable Resin?

Yes. Tough 2000 has a typical yield strength of 44 MPa (6.38 ksi) against 22 MPa (3.19 ksi) for Durable Resin — about 100% more. Tensile strength is 50 MPa (7.25 ksi) vs 28 MPa (4.06 ksi).

Which is cheaper, Durable Resin or Tough 2000?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose Durable Resin over Tough 2000?

Pick Durable Resin when the part is bent, formed or impact-loaded. Pick Tough 2000 when strength drives the design, or when the part sees heat.
