# What filament should I use when the part has to bend?

Use TPU when the part has to bend. Prusa’s material guide lists Flex as the bendable material, and the spools below are TPU records that include a nozzle temperature.

Pick the stiffness on purpose. 95A is the default bendable part. Drop to 90A when the part has to fold, and leave PLA off the list.

## What the community says

The practical split on r/3Dprinting is PLA for ordinary parts, PETG when it has to be tougher, and TPU when it has to flex. The same thread says TPU is slower, needs to be dry, and often has to skip the automatic feeder. Cosplay replies use TPU for straps and joints and keep the shells in PETG or PLA.
