TPU Forward AM Ultrasint TPU01 vs TPU GF20

Polymer · TPU grade comparison

Forward AM Ultrasint TPU01 and TPU GF20 are two grades of the same polymer grade, TPU: Forward AM Ultrasint TPU01 versus GF20 (20 % glass-fibre reinforced TPU). The chemistry is identical, so every difference below comes from the condition. TPU GF20 is the stronger of the two: tensile strength 45 MPa (6.53 ksi) against 9 MPa (1.31 ksi) for Forward AM Ultrasint TPU01, about 5.0 times as much. In exchange, Forward AM Ultrasint TPU01 is the more ductile: elongation 280% versus 25% for TPU GF20. Forward AM Ultrasint TPU01 is lighter (1.1 g/cm³ vs 1.35 g/cm³ for TPU GF20) and TPU GF20 is stiffer (2 GPa vs 0.085 GPa).

Forward AM Ultrasint TPU01Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

TPU GF20Choose it when strength drives the design.

Forward AM Ultrasint TPU01 vs TPU GF20 — frequently asked

Is TPU GF20 stronger than Forward AM Ultrasint TPU01?

Yes. TPU GF20 has a typical tensile strength of 45 MPa (6.53 ksi) against 9 MPa (1.31 ksi) for Forward AM Ultrasint TPU01 — about 5.0 times as much.

Which grade does FabDigit quote by default, Forward AM Ultrasint TPU01 or GF20?

Shore A 85 is the default TPU condition in the FabDigit quote flow (neither Forward AM Ultrasint TPU01 nor GF20). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

When should I choose Forward AM Ultrasint TPU01 over TPU GF20?

Pick Forward AM Ultrasint TPU01 when the part is bent, formed or impact-loaded, or when weight is the constraint. Pick TPU GF20 when strength drives the design.
