Rigur vs VeroBlackPlus
Polymer · grade comparison
Rigur and VeroBlackPlus are both polymer grades. VeroBlackPlus is the stronger of the two: yield strength 50 MPa (7.25 ksi) against 38 MPa (5.51 ksi) for Rigur, about 32% more; tensile strength follows at 55 MPa (7.98 ksi) vs 42 MPa (6.09 ksi). In exchange, Rigur is the more ductile: elongation 32% versus 17% for VeroBlackPlus. VeroBlackPlus is stiffer (2.5 GPa vs 1.9 GPa) and VeroBlackPlus runs hotter in service (45°C vs 40°C continuous). On the shop floor, VeroBlackPlus machines more easily (good vs fair).
RigurChoose it when the part is bent, formed or impact-loaded.
VeroBlackPlusChoose it when strength drives the design, or when the part sees heat.
Rigur vs VeroBlackPlus: 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.

Rigur vs VeroBlackPlus — frequently asked
Is VeroBlackPlus stronger than Rigur?
Yes. VeroBlackPlus has a typical yield strength of 50 MPa (7.25 ksi) against 38 MPa (5.51 ksi) for Rigur — about 32% more. Tensile strength is 55 MPa (7.98 ksi) vs 42 MPa (6.09 ksi).
Which is cheaper, Rigur or VeroBlackPlus?
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, Rigur or VeroBlackPlus?
VeroBlackPlus. Its machinability rates good (55/100) against fair (45/100) for Rigur; for welding the order is VeroBlackPlus first (not recommended, 10/100) then Rigur (not recommended, 5/100).
