Denture Base Resin vs Formlabs Rigid 10K
Polymer · grade comparison
Denture Base Resin and Rigid 10K are both polymer grades. Rigid 10K is the stronger of the two: tensile strength 75 MPa (10.9 ksi) against 48 MPa (6.96 ksi) for Denture Base Resin, about 56% more. In exchange, Denture Base Resin is the more ductile: elongation 4% versus 2.5% for Rigid 10K. Denture Base Resin is lighter (1.18 g/cm³ vs 1.55 g/cm³ for Rigid 10K) and Rigid 10K is stiffer (5.5 GPa vs 2.2 GPa). On the shop floor, Denture Base Resin machines more easily (good vs fair) and Rigid 10K sits in a lower cost tier (premium, $$$) than Denture Base Resin (high, $$$$).
Denture Base 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.
Denture Base 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.
