Dental Model Resin vs Formlabs Rigid 10K
Polymer · grade comparison
Dental Model Resin and Rigid 10K are both polymer grades. Rigid 10K is the stronger of the two: tensile strength 75 MPa (10.9 ksi) against 58 MPa (8.41 ksi) for Dental Model Resin, about 29% more. In exchange, Dental Model Resin is the more ductile: elongation 5% versus 2.5% for Rigid 10K. Dental Model Resin is lighter (1.18 g/cm³ vs 1.55 g/cm³ for Rigid 10K) and Rigid 10K is stiffer (5.5 GPa vs 2.4 GPa). On the shop floor, Dental Model Resin machines more easily (good vs fair) and Rigid 10K sits in a lower cost tier (premium, $$$) than Dental Model Resin (high, $$$$).
Dental Model ResinChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Rigid 10KChoose it when strength drives the design, or when the part sees heat.
Dental Model Resin vs Rigid 10K: 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.
