TPU As Printed vs TPU Formlabs TPU 90A

Polymer · TPU grade comparison

TPU As Printed and Formlabs TPU 90A Powder are two grades of the same polymer grade, TPU: As Printed (as built (as printed)) versus Formlabs TPU 90A. The chemistry is identical, so every difference below comes from the condition. TPU As Printed is the stronger of the two: tensile strength 28 MPa (4.06 ksi) against 8.7 MPa (1.26 ksi) for Formlabs TPU 90A Powder, about 3.2 times as much. TPU As Printed is the more ductile: elongation 380% versus 310% for Formlabs TPU 90A Powder. Formlabs TPU 90A Powder is lighter (1.14 g/cm³ vs 1.2 g/cm³ for TPU As Printed).

TPU As PrintedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Formlabs TPU 90A PowderChoose it when weight is the constraint.

TPU As Printed vs Formlabs TPU 90A Powder — frequently asked

Is TPU As Printed stronger than Formlabs TPU 90A Powder?

Yes. TPU As Printed has a typical tensile strength of 28 MPa (4.06 ksi) against 8.7 MPa (1.26 ksi) for Formlabs TPU 90A Powder — about 3.2 times as much.

Which grade does FabDigit quote by default, As Printed or Formlabs TPU 90A?

Shore A 85 is the default TPU condition in the FabDigit quote flow (neither As Printed nor Formlabs TPU 90A). 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 TPU As Printed over Formlabs TPU 90A Powder?

Pick TPU As Printed when strength drives the design, or when the part is bent, formed or impact-loaded. Pick Formlabs TPU 90A Powder when weight is the constraint.
