TPU Filament AnyCubic IPHTPBK-102 Black — Flexible 1 kg Spool for FDM 3D Printing

AnyCubic TPU Filament IPHTPBK-102 in black is a flexible thermoplastic polyurethane supplied on a 1 kg spool for FDM 3D printers. It combines high elasticity and abrasion resistance, making it suitable for parts that require bending, impact damping or contact with oils. Use correct extrusion and bed temperatures and follow drying recommendations to achieve consistent prints and reliable layer adhesion.

Advantages

TPU provides a rubber-like, soft surface with very high elongation at break and good tear strength, offering durable, wear-resistant prints. The filament resists abrasion and oils, prints with stable flow to reduce clumping, and is available in vivid black suitable for functional and aesthetic parts.

Suitable for

• Wearable items such as wristbands and straps
• Phone cases and protective covers
• Vibration dampers and bumpers
• Flexible prototypes, seals and gaskets
• Toy wheels and moving parts requiring elasticity

When it may not be suitable

TPU is not ideal for very rigid structural parts or applications that require high dimensional stability at elevated temperatures above its deformation resistance. Thin, long unsupported spans may be difficult to print without appropriate settings or support due to the material’s flexibility.

How to use

Load the 1 kg spool into an FDM printer compatible with flexible filaments, set the nozzle temperature to within 195–230°C and the heated bed to 50–60°C. Use a slower print speed within the recommended range and enable retraction and stringing reduction profiles if available. Pre-dry the filament at 70–80°C for about 8 hours if it has absorbed moisture, then store in a dry container to maintain print quality. Adjust extrusion multiplier and first-layer settings to ensure good bed adhesion and consistent extrusion.

What to consider before purchase

• Ensure your printer is capable of handling flexible filaments and that the feed path minimizes sharp bends
• Verify the recommended temperature range matches your hotend and build plate capabilities
• Plan for pre-drying and dry storage if you work in humid environments
• Consider part requirements: TPU is flexible and wear-resistant but not suited for rigid structural elements

Usage recommendations

For best results, print at the lower end of the speed range with tuned retraction settings, pre-dry the filament when necessary, and use a direct or well-guided filament path to avoid feeding issues when printing flexible parts.
