What is TPU 90A good for?

Flexible parts that bend or absorb shock: gaskets, seals, grippers, phone cases, wearables and vibration dampers. It is too soft for rigid structural parts.

Will it work on my printer?

It is designed for Bambu Lab X1, P1P, P1S and A1 series printers and most 1.75 mm direct-drive FDM printers. Bowden-tube extruders usually feed TPU poorly.

How fast can I print it?

Slowly. Flexible filament needs reduced speeds to avoid buckling and jams, so expect much slower prints than with PLA or PETG.

How should I store it?

Keep it in a dry, cool place. Once the vacuum seal is broken, TPU absorbs moisture, so dry the spool before use if prints turn stringy or bubbly.

Does it come with print settings?

Yes, detailed print settings are printed on the spool or package.

Is it the same as PLA or PETG?

No. TPU is flexible and rubbery, while PLA and PETG are rigid. Use TPU when you need bend and shock absorption.

Our take on the Bambu Lab 3D Printer Filament TPU 90A - White-Filament with spool

Bambu Lab TPU 90A is a flexible 1.75 mm filament for FDM printers, supplied on a spool and vacuum-sealed with desiccant. Its 90A hardness sits in the middle of the flexible range: soft enough to bend and absorb shock, firm enough to feed through a direct-drive extruder and hold detailed shapes. It suits phone cases, gaskets, grippers, wearables and vibration-damping parts. Compared with generic TPU, Bambu's spool is tuned for its own X1, P1 and A1 machines, but flexible filament remains slower and fussier to print than rigid PLA or PETG, and Bowden-tube printers often struggle with it.

Pros

90A hardness balances flexibility and stiffness
Consistent 1.75 mm diameter for reliable feeding
Vacuum-sealed with desiccant to keep moisture out
Low warping and strong layer bonding
Print settings documented on the spool or package
Works on Bambu Lab X1, P1, P1S and A1 series

Cons

Flexible filament needs slow print speeds, not the 300 mm/s claimed
Bowden-tube printers feed TPU poorly
Absorbs moisture quickly once opened
Not suited to rigid structural parts
White color shows dirt and scuffs on flexible parts

What reviewers say

Owners of Bambu Lab printers report clean, consistent extrusion and good layer bonding from this TPU, with few clogs on direct-drive machines. Most complaints center on print speed and moisture, not the filament itself.

What people mention

Print speedCriticisedUsers say TPU must be printed slowly, well below the high speeds quoted for rigid filaments.
Layer bondingPraisedOwners report strong layer adhesion and durable, tear-resistant flexible parts.
MoistureMixedThe vacuum seal helps, but users say opened spools absorb moisture and need drying.
ExtrusionPraisedConsistent diameter gives smooth feeding and few clogs on direct-drive printers.
Printer fitMixedWorks well on Bambu Lab direct-drive machines; Bowden-tube printers handle it poorly.
