TPU Filament AnyCubic IPHTPGY-102 (Gray) — flexible 3D printing material, 1 kg spool

AnyCubic TPU Filament IPHTPGY-102 (Gray) is a flexible thermoplastic polyurethane supplied on a 1 kg spool for FDM/FFF 3D printers. The filament combines rubber-like softness with high tensile strength and abrasion resistance, making it suitable for prints that require elasticity, impact damping and long-term wear resistance.

Advantages

The filament offers very high elongation at break (≈697%), good tensile strength and a Shore hardness of 95A, providing a balance of flexibility and structural durability. It resists abrasion and oils and prints stably with reduced material clumping when appropriate printer settings are used. Pre-made TPU profiles in slicer software help reduce stringing and improve surface quality.

Suitable for

• Wearable parts (wristbands, straps)
• Phone cases and protective covers
• Vibration dampers and gaskets
• Toy wheels and flexible mechanical parts
• Functional prototypes requiring elasticity

When it may not be suitable

This TPU filament is not optimal for rigid structural parts that require high dimensional stability and no elasticity. It is also unsuitable for printers that cannot handle flexible filaments or lack a suitable feeding path, as excessive bending in the filament path can cause jams or poor extrusion.

How to use

Load the 1 kg spool into an FDM/FFF printer configured for flexible filaments and set the nozzle temperature between 195 and 230°C and the heated bed to 50–60°C. Use slicer TPU profiles where available to reduce stringing; choose conservative retraction settings and a print speed within 50–150 mm/s depending on your printer and part geometry. If the filament has absorbed moisture, dry it at 70–80°C for about 8 hours before printing to avoid bubbles and poor surface quality. Use a direct or well-guided Bowden path designed for flexible materials to minimise feeding issues.

What to consider before purchase

• Ensure your printer supports flexible TPU filaments and has an appropriate filament path.
• Plan for pre-drying if the filament has been exposed to humidity.
• Check that desired part applications require elasticity rather than rigid strength.
• Confirm nozzle and bed temperature ranges are compatible with your printer.

Usage recommendations

For best results print with reduced retraction, moderate speeds and use a direct-drive or constrained Bowden feeder; dry the filament before use if stored in humid conditions. These settings help produce flexible, durable prints such as wristbands, phone cases and vibration dampers.
