DAIP vs MF
Polymer · grade comparison
DAIP and MF are both polymer grades. MF is the stronger of the two: tensile strength 70 MPa (10.2 ksi) against 55 MPa (7.98 ksi) for DAIP, about 27% more. MF is the more ductile: elongation 0.8% versus 0.6% for DAIP. MF is lighter (1.5 g/cm³ vs 1.8 g/cm³ for DAIP) and DAIP is stiffer (11 GPa vs 9 GPa). On the shop floor, MF sits in a lower cost tier (standard, $$) than DAIP (high, $$$$).
DAIPChoose it when the part sees heat.
MFChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
DAIP vs MF: 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.

DAIP vs MF — frequently asked
Is MF stronger than DAIP?
Yes. MF has a typical tensile strength of 70 MPa (10.2 ksi) against 55 MPa (7.98 ksi) for DAIP — about 27% more.
Which is cheaper, DAIP or MF?
MF is the lower-cost material: it sits in the standard tier ($$) while DAIP is high ($$$$). 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 DAIP over MF?
Pick DAIP when the part sees heat. Pick MF when strength drives the design, or when the part is bent, formed or impact-loaded.
