TPU Filament AnyCubic Transparent Blue 1 kg — flexible 3D printing material

AnyCubic TPU Filament Transparent Blue is a 1 kg spool of flexible thermoplastic polyurethane designed for 3D printing. The material has a rubber-like structure with very high elongation at break and good abrasion and oil resistance, making it suitable for parts that require elasticity and long-term durability while maintaining vivid color and stable extrusion.

Advantages

TPU offers a soft, pleasant-to-touch surface and can bend freely without damage, allowing production of functional elastic parts. The filament provides high tear resistance, wear resistance and stable printing behaviour with reduced risk of clumping when print settings are correct. It is available in a transparent blue shade that retains color under typical usage conditions.

Suitable for

• Wearable parts such as wristbands and straps
• Phone cases and protective covers
• Vibration dampers and shock-absorbing components
• Gaskets, seals and flexible connectors
• Toy wheels and small flexible mechanical parts

When it may not be suitable

This TPU filament is not suitable for applications requiring rigid or highly structural components where high stiffness is needed. It also may not be the best choice for printers that cannot reliably handle flexible filaments; such printers can experience feeding issues or stringing if settings are not adjusted.

How to use

Load the 1 kg spool into a printer compatible with flexible filaments and set the nozzle temperature between 195 and 230°C with a heated bed at 50–60°C. Use printing speeds in the 50–150 mm/s range and enable a TPU or flexible material profile in your slicer to reduce stringing. Pre-dry the filament before printing if it has absorbed moisture; recommended curing is 70–80°C for 8 hours to remove residual moisture and improve print quality. Use direct drive or a well-tuned Bowden setup with slow retraction and low print speed for optimal results.

What to consider before purchase

• Ensure your 3D printer supports flexible TPU filaments and can maintain recommended temperatures
• Plan for pre-drying or curing to minimise moisture-related defects
• Check that the transparent blue color and hardness (95A) match your application requirements
• Confirm the recommended print speed and extrusion settings are compatible with your printer setup

Usage recommendations

For best results, store the filament in a dry container with desiccant, use a dedicated TPU profile in your slicer, and perform a small test print to fine-tune temperature and retraction settings before printing final parts.
