TPU Filament

Thermoplastic Polyurethane

S
Also known as:Thermoplastic PolyurethaneTPE
Family:Flexible

Why Use TPU?

  • Perfect layer adhesion; extremely impact resistant; nearly indestructible
  • Great for combat robots, tactical/rough-use parts
  • Rubber-like parts (gaskets, grips, bumpers, wheels)

Things to Consider

  • Slow printing; retraction can cause jams (especially in Bowden setups)
  • Stringing is common
  • Very moisture sensitive; wet TPU prints poorly

TPU Variants

TPU 95A (common)

Benefits:

  • + Balanced flexibility and printability

Caveats:

  • - Still prefers direct drive and slow speeds

Soft TPU (85A-90A)

Benefits:

  • + More rubbery parts

Caveats:

  • - Harder to feed; needs excellent filament path constraints
