Detailed Description

# Prusament TPU 95A

Overview

Prusament TPU 95A is a flexible 1.75 mm TPU filament with Shore 95A hardness, extreme wear resistance, high impact durability, very low moisture absorption and strong hydrolysis resistance. Thin sections remain soft and flexible, while thicker walls and higher infill create stronger, more rigid parts.

It is well suited to grips, protective covers, cable protectors, O-rings, spacers, tires and other flexible engineering components. For rigid alternatives, compare Prusament PETG and Polymaker PLA Pro.

Key Benefits

  • Extreme wear resistance
  • High impact resistance
  • Very low moisture absorption
  • Hydrolysis resistant
  • Flexible to approximately -50°C
  • Non-abrasive
  • No enclosure required

Best For

  1. Flexible prototypes
  2. Grips and protective covers
  3. O-rings and spacers
  4. Cable protectors
  5. Tires and flexible components
  6. Wear-resistant engineering parts

Note: Prusa recommends approximately 230 ±10°C nozzle temperature and 65 ±10°C bed temperature. Flexible-filament feeding may require printer-specific adjustments.


Printing Compatibility

Recommended Setup

  • 230 ±10°C nozzle
  • 65 ±10°C heated bed
  • Standard nozzle suitable
  • PA Nylon or Satin sheet preferred
  • PP and Textured sheets also supported with suitable preparation
  • Enclosure not required

The Prusa CORE One+ is a relevant Prusa platform because TPU 95A is optimized for Nextruder-equipped machines. Other indexed TPU-capable printers include the Bambu Lab A1, Bambu Lab P2S and Creality K2 Plus, with printer-specific feeding and accessory guidance.

Important: Smooth PEI is not recommended for direct TPU printing because adhesion can be excessive. Use a suitable separation layer if required.

Note: Mechanical behaviour depends strongly on wall thickness, infill, print orientation and geometry.


Processing and Handling

Print at approximately 230 ±10°C with a 65 ±10°C bed. TPU normally prints slower than rigid filament because flexible material requires controlled feeding.

Drying is usually unnecessary under good storage conditions. If moisture-related issues occur, dry at 60°C for at least 4 hours and store the filament dry.

For parts that do not require flexibility, Prusament PETG provides a tough rigid alternative, while Polymaker PLA Pro is better suited to rigid high-speed prototypes and fixtures.

Recommended use: Choose Prusament TPU 95A when flexibility, wear resistance and impact durability are required. Choose Prusament PETG for tough rigid parts or Polymaker PLA Pro for rigid high-speed prototypes.


Callout Section

Recommended use: Best for flexible engineering components such as grips, seals, protective parts, cable protectors and tires. For a Prusa workflow, use a suitable profile on the Prusa CORE One+.
