Dental Model Resin vs Formlabs Tough 2000
Polymer · grade comparison
Dental Model Resin and Tough 2000 are both polymer grades. Dental Model Resin is the stronger of the two: tensile strength 58 MPa (8.41 ksi) against 50 MPa (7.25 ksi) for Tough 2000, about 16% more. In exchange, Tough 2000 is the more ductile: elongation 22% versus 5% for Dental Model Resin, and Dental Model Resin is harder (86 Shore D vs 80 Shore D). Dental Model Resin runs hotter in service (55°C vs 50°C continuous). On the shop floor, Tough 2000 sits in a lower cost tier (standard, $$) than Dental Model Resin (high, $$$$).
Dental Model 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 Model 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.
