TPU

Thermoplastic Polyurethane

TPU is flexible, elastic, and forgiving to print in terms of warping, but demands slow speeds, very low cooling, a release agent on the bed, and mandatory drying to prevent moisture-related jams and defects, making it more challenging to dial in than PLA but easier than ABS in terms of environmental requirements.

Skill level: Moderate

This filament is moderately demanding to print, flexible. Worth watching: it can be moisture-sensitive and low on heat resistance.

Things to watch

Soaks up moisture quickly, keep it sealed and dry before printing
Prone to stringing, tune retraction and keep the filament dry
Softens in heat, not for hot cars or near heat sources
Shrinks as it cools, which can affect dimensional accuracy

Strengths

Solid strength for everyday parts
Wear-resistant for moving and rubbing parts
Flexible and rubber-like
Layers bond strongly for clean, watertight prints
Stays flat, very little warping
Food-safe potential with the right setup
