Durus vs VeroBlue
Polymer · grade comparison
Durus and VeroBlue are both polymer grades. VeroBlue is the stronger of the two: yield strength 48 MPa (6.96 ksi) against 22 MPa (3.19 ksi) for Durus, about 118% more; tensile strength follows at 55 MPa (7.98 ksi) vs 25 MPa (3.63 ksi). In exchange, Durus is the more ductile: elongation 45% versus 17% for VeroBlue, and VeroBlue is harder (84 Shore D vs 68 Shore D). VeroBlue is stiffer (2.5 GPa vs 1.1 GPa). On the shop floor, VeroBlue machines more easily (good vs fair).
DurusChoose it when the part is bent, formed or impact-loaded.
VeroBlueChoose it when strength drives the design, or when the part is machined in volume.
Durus vs VeroBlue: 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.

Durus vs VeroBlue — frequently asked
Is VeroBlue stronger than Durus?
Yes. VeroBlue has a typical yield strength of 48 MPa (6.96 ksi) against 22 MPa (3.19 ksi) for Durus — about 118% more. Tensile strength is 55 MPa (7.98 ksi) vs 25 MPa (3.63 ksi).
Which is cheaper, Durus or VeroBlue?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Durus or VeroBlue?
VeroBlue. Its machinability rates good (55/100) against fair (45/100) for Durus.
