TPU – flexible filament for elastic parts

TPU – Thermoplastic Polyurethane

TPU is a flexible filament for rubber-like parts; compared to PLA and PETG it is much more elastic, but printing is slower and requires careful tuning.
Advantages: high flexibility and elasticity, abrasion and impact resistance, good chemical resistance.
Disadvantages: more difficult to print (especially with Bowden setups), slow print speeds, less fine detail than rigid filaments.
