Prusament TPU 95A Natural 500 g (NFC)

Prusament TPU 95A Natural 500 g (NFC)

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

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

Main advantages of TPU 95A material

• Hardness 95A (Shore) – soft and flexible in thin walls, solid and almost "indestructible" in thicker profiles
• High wear and abrasion resistance – suitable for stressed functional parts
• Very low water absorption and high hydrolysis resistance – fewer moisture problems, longer print life
• Flexibility maintained even at low temperatures (down to approx. -50 °C)
• High chemical resistance – especially against oils and greases
• Low stringing and high printing reliability compared to common TPUs
• Made in Prusa Research, precision ±0,06 mm throughout the entire spool
• Integrated NFC/OpenPrintTag chip – storage of material parameters directly in the spool (compatible across ecosystems)

Suitable Use

Prusament TPU 95A Natural is ideal for:

• O-rings, seals, silent blocks, washers, and bumpers
• Flexible covers, protective packaging, 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-translucent) is suitable both for functional parts and for visual inspection of the internal structure (infill, layers, potential bubbles, etc.).

Printing Settings (Guideline)

According to the manufacturer Prusa Research's recommendations:

• Nozzle temperature: approx. 230 ± 10 °C
• Bed temperature: approx. 65 ± 10 °C
• Recommended printing surfaces:
  • Nylon PA sheet – most recommended surface
  • Satin spring steel sheet – a very good choice
  • PP / textured sheet – possible, but may have higher adhesion
• 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 speed can lead to pressure buildup and feeding errors)

Most modern printers with a direct extruder offer very good results with TPU 95A. For bowden systems, significantly lower speeds and careful retraction tuning must be expected.

Tips for Successful TPU Printing

• Storage: thanks to low water absorption, the material is not as sensitive as other flexible filaments, yet it is advisable to store it in a dry place. If exposed to high humidity for a long time, dry for approx. 4 hours at 60 °C.
• Retractions: 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 solid functional parts
• Large models may have a tendency to warp; a brim, higher bed temperature, and suitable surface (PA/Nylon, Satin) will help.

NFC / OpenPrintTag Spool

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

• Stores key material information (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 chip is rewritable and an open standard – also suitable for custom workflows.

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