Durable Resin vs Formlabs High Temp

Polymer · grade comparison

Durable Resin and High Temp are both polymer grades. High Temp is the stronger of the two: tensile strength 50 MPa (7.25 ksi) against 28 MPa (4.06 ksi) for Durable Resin, about 79% more. In exchange, Durable Resin is the more ductile: elongation 55% versus 2.8% for High Temp, and High Temp is harder (88 Shore D vs 70 Shore D). Durable Resin is lighter (1.12 g/cm³ vs 1.19 g/cm³ for High Temp) and High Temp is stiffer (3.5 GPa vs 1 GPa). On the shop floor, Durable Resin sits in a lower cost tier (standard, $$) than High Temp (premium, $$$).

Durable ResinChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

High TempChoose it when strength drives the design, or when the part sees heat.

Durable Resin vs High Temp — frequently asked

Is High Temp stronger than Durable Resin?

Yes. High Temp has a typical tensile strength of 50 MPa (7.25 ksi) against 28 MPa (4.06 ksi) for Durable Resin — about 79% more.

Which is cheaper, Durable Resin or High Temp?

Durable Resin is the lower-cost material: it sits in the standard tier ($$) while High Temp is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

When should I choose Durable Resin over High Temp?

Pick Durable Resin when the part is bent, formed or impact-loaded, or when weight is the constraint. Pick High Temp when strength drives the design, or when the part sees heat.
