High Temp vs Formlabs Rigid 10K
Polymer · grade comparison
High Temp and Rigid 10K are both polymer grades. Rigid 10K is the stronger of the two: tensile strength 75 MPa (10.9 ksi) against 50 MPa (7.25 ksi) for High Temp, about 50% more. In exchange, High Temp is the more ductile: elongation 2.8% versus 2.5% for Rigid 10K. High Temp is lighter (1.19 g/cm³ vs 1.55 g/cm³ for Rigid 10K) and Rigid 10K is stiffer (5.5 GPa vs 3.5 GPa). On the shop floor, High Temp machines more easily (good vs fair).
High TempChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Rigid 10KChoose it when strength drives the design.
High Temp 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.

High Temp vs Rigid 10K — frequently asked
Is Rigid 10K stronger than High Temp?
Yes. Rigid 10K has a typical tensile strength of 75 MPa (10.9 ksi) against 50 MPa (7.25 ksi) for High Temp — about 50% more.
Which is cheaper, High Temp or Rigid 10K?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, High Temp or Rigid 10K?
High Temp. Its machinability rates good (55/100) against fair (40/100) for Rigid 10K.
