Dental Resin vs Formlabs Tough 2000
Polymer · grade comparison
Dental Resin and Tough 2000 are both polymer grades. Dental Resin is the stronger of the two: yield strength 48 MPa (6.96 ksi) against 44 MPa (6.38 ksi) for Tough 2000, about 9% more; tensile strength follows at 55 MPa (7.98 ksi) vs 50 MPa (7.25 ksi). In exchange, Tough 2000 is the more ductile: elongation 22% versus 6% for Dental Resin, and Dental Resin is harder (85 Shore D vs 80 Shore D). Tough 2000 is stiffer (2.4 GPa vs 2.2 GPa) and Dental Resin runs hotter in service (70°C vs 50°C continuous). On the shop floor, Tough 2000 sits in a lower cost tier (standard, $$) than Dental Resin (high, $$$$).
Dental ResinChoose it when strength drives the design, or when the part sees heat.
Tough 2000Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
Dental 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.
