Digital ABS vs Rigur
Polymer · grade comparison
Digital ABS and Rigur are both polymer grades. Digital ABS is the stronger of the two: tensile strength 57 MPa (8.27 ksi) against 42 MPa (6.09 ksi) for Rigur, about 36% more. Digital ABS is harder — 86 Shore D against 80 Shore D for Rigur — which matters for wear surfaces and threads. Digital ABS is stiffer (2.8 GPa vs 1.9 GPa) and Digital ABS runs hotter in service (50°C vs 40°C continuous). On the shop floor, Digital ABS machines more easily (good vs fair), Digital ABS welds better (poor vs not recommended), and Rigur sits in a lower cost tier (high, $$$$) than Digital ABS (specialty, $$$$$).
Digital ABSChoose it when strength drives the design, or when surface hardness matters.
RigurChoose it when cost is the deciding factor.
Digital ABS vs Rigur: 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.

Digital ABS vs Rigur — frequently asked
Is Digital ABS stronger than Rigur?
Yes. Digital ABS has a typical tensile strength of 57 MPa (8.27 ksi) against 42 MPa (6.09 ksi) for Rigur — about 36% more.
Which is cheaper, Digital ABS or Rigur?
Rigur is the lower-cost material: it sits in the high tier ($$$$) while Digital ABS is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, Digital ABS or Rigur?
Digital ABS. Its machinability rates good (55/100) against fair (45/100) for Rigur; for welding the order is Digital ABS first (poor, 15/100) then Rigur (not recommended, 5/100).
