Prusament TPU 95A Natural 500g (NFC)

Prusament TPU 95A Natural 500g (NFC)

Prusament TPU 95A is a professional flexible filament manufactured directly by Prusa Research. The Natural variant in 500 g packaging is ideal for functional, tough and wear-resistant parts that must remain flexible while also being highly durable.

Thanks to precisely controlled production, a solid TPU core based on ether diol and very low moisture absorption, this is a material that prints significantly easier than common TPU and is suitable even for long and repeated print runs.

Main advantages of TPU 95A material

• Hardness 95A (shore) – soft and flexible in thin walls, strong and almost “indestructible” in thicker profiles
• High wear and abrasion resistance – suitable for heavily stressed functional parts
• Very low moisture absorption and high resistance to hydrolysis – fewer moisture-related issues, longer print life
• Elasticity maintained even at low temperatures (down to around -50 °C)
• High chemical resistance – especially to oils and lubricants
• Low stringing and high print reliability compared to common TPU
• Manufactured at Prusa Research, accuracy ±0.06 mm over the entire spool
• Integrated NFC/OpenPrintTag label – material parameters stored directly in the spool (cross-ecosystem compatible)

Suitable applications

Prusament TPU 95A Natural is ideal for:

• O-rings, seals, silent blocks, washers and stops
• Flexible covers, protective cases, bumpers and edge protectors
• Flexible parts of sports and outdoor equipment
• Structural parts exposed to vibration, bending and repeated stress
• Wheels, pulleys, stops, shock absorbers
• Prototypes of soft and semi-flex parts (ergonomic handles, grips, sleeves)

The color Natural (natural, semi-transparent) is suitable both for functional parts and for visual inspection of the internal structure (infill, layers, possible bubbles, etc.).

Printing settings (indicative)

According to the recommendations of the manufacturer Prusa Research:

• Nozzle temperature: approx. 230 ± 10 °C
• Bed temperature: approx. 65 ± 10 °C
• Recommended build surfaces:
  • Nylon PA sheet – most recommended surface
  • Satin spring steel sheet – a very good choice
  • PP / textured sheet – possible, but adhesion may be higher
• Smooth PEI sheet: not recommended without a separation layer; use glue / separation layer, otherwise there is a risk of damaging the sheet
• Print speed: rather low to medium (TPU is flexible, too high a speed can lead to overpressure and feeding errors)

Most modern printers with a direct extruder offer very good results with TPU 95A. With Bowden systems, you need to count on significantly lower speeds and careful tuning of retractions.

Tips for successful TPU printing

• Storage: thanks to its low moisture absorption, the material is not as sensitive as other flexible filaments, but it is still advisable to store it in a dry environment. After prolonged exposure to high humidity, dry for approx. 4 hours at 60 °C if necessary.
• Retraction: set shorter and slower retractions to avoid “chewing” of the filament in the feeder.
• Infill vs. stiffness:
  • low infill and thin walls → very soft and flexible parts
  • higher infill and more perimeters → very tough and strong functional parts
• Large models may tend to warp; brim, a higher bed temperature and a suitable surface (PA/Nylon, Satin) will help.

NFC / OpenPrintTag spool

This filament version is supplied on the new Prusament spool with an NFC/OpenPrintTag label:

• Stores key information about the material (type, color, temperatures, remaining amount, etc.).
• Can be read using the Prusa mobile app or compatible solutions.
• Works completely offline, without the need for cloud services.
• The tag is rewritable and an open standard – suitable for custom workflows as well.

This makes working with the filament more convenient and minimizes the risk of incorrect material settings.
