TPU 3D Printing — Flexible, Rubber-Like

TPU is a flexible filament that behaves like rubber — gaskets, vibration dampers, phone cases, shoe insoles. $0.070/cm³ at 2.0× PLA. Prints slowly on a direct-drive extruder.

When to choose TPU

TPU is the right pick when the part must flex, compress, or grip. Phone cases, shoe insoles, gaskets, O-rings, vibration dampers, drone battery straps, tool grips, medical wearables (bracelets, straps), dust covers that need a snug seal, and any squishy functional part.

When to pick something else

Skip TPU for rigid structural parts — you're paying more for less strength. Skip for parts that need a crisp, sharp aesthetic. Skip for high-temp applications (keep under 60°C sustained). Our lead time on TPU is typically 1 day longer than rigid jobs because of the slow print speed.

TPU Properties & Datasheet

Verified against manufacturer datasheets and our own print testing at the San Diego shop.

Tensile strength26 MPaLower than rigid filaments — you're paying for flex
Shore hardness95A (common)Feels like a pencil eraser
Heat deflection60 °CKeep below that for load-bearing
Elongation at break450%Huge stretch before rupture
Chemical resistanceExcellentOils, greases, most solvents
Abrasion resistanceExcellentOutperforms most rigid plastics
Print speedSlow (30mm/s typical)Flexible filament takes time; it shows in lead time
Layer adhesionGoodBut layer lines are visible

DESIGN TIPS

Designing for TPU

  • 01Walls: TPU parts compress, so design for the compressed dimension if you need a seal.
  • 02Infill: 25–50% for cushioning. 100% only if you need a solid rubber block (expensive).
  • 03Supports: we avoid them when possible; TPU supports are brutal to remove.
  • 04Shore hardness matters — we stock 95A (firm) by default; softer 85A on request.
  • 05Holes tighten in TPU — design 0.3mm oversized for snug fits.

CUSTOMER WORK

Real parts we've printed in TPU

Drone battery strap

95A TPU strap for a 5" freestyle drone — absorbs vibration and doesn't snap in freezing temps.

Industrial gasket

Custom-shaped TPU gasket for a pump flange — outperformed off-the-shelf O-rings.

Phone case

Drop-tested custom case for a one-off phone model not on retail shelves.

TPU FAQ

How much does TPU 3D printing cost?+
As a concrete example, our reference 7.8 cm³ bracket (50×30×40 mm) prints in TPU at $8.22 per part at standard quality and infill — that's the exact number our instant quote engine produces for that geometry. The material rate is $0.070/cm³ (2× PLA); quotes also include machine time, and orders have a $20 minimum. Upload your file for an exact price in seconds.
What is TPU best for?+
TPU is the right pick when the part must flex, compress, or grip. Phone cases, shoe insoles, gaskets, O-rings, vibration dampers, drone battery straps, tool grips, medical wearables (bracelets, straps), dust covers that need a snug seal, and any squishy functional part.
When should I NOT use TPU?+
Skip TPU for rigid structural parts — you're paying more for less strength. Skip for parts that need a crisp, sharp aesthetic. Skip for high-temp applications (keep under 60°C sustained). Our lead time on TPU is typically 1 day longer than rigid jobs because of the slow print speed.
What does TAKT 3D's TPU print setup require?+
Direct-drive extrusion and slow print speed (~30mm/s) required. Standard brass nozzle; enclosed chamber optional. All of our TPU jobs use filament dried the same day to avoid moisture-induced defects, and every spool is logged against the part batch for traceability.
How long is TPU 3D printing turnaround?+
Standard turnaround for TPU is 5–7 business days. Expedited (3 days) is +30% (minimum $35); rush (1–2 days) is +60% (minimum $60). On rush, small TPU orders can ship inside 48 hours from our San Diego shop.
