Elastic Resin vs Formlabs Tough 2000
Polymer · grade comparison
Elastic Resin and Tough 2000 are both polymer grades. Tough 2000 is the stronger of the two: tensile strength 50 MPa (7.25 ksi) against 3 MPa (0.464 ksi) for Elastic Resin, about 16 times as much. In exchange, Elastic Resin is the more ductile: elongation 160% versus 22% for Tough 2000, and Tough 2000 is harder (80 Shore D vs 13 Shore D). Tough 2000 is stiffer (2.4 GPa vs 0 GPa) and Elastic Resin runs hotter in service (60°C vs 50°C continuous). On the shop floor, Tough 2000 machines more easily (good vs not recommended) and Tough 2000 sits in a lower cost tier (standard, $$) than Elastic Resin (high, $$$$).
Elastic ResinChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Tough 2000Choose it when strength drives the design, or when the part is machined in volume.
Elastic Resin vs Tough 2000: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
