TPU Filament AnyCubic Transparent Purple 1 kg — Flexible 3D Printing Material

AnyCubic TPU Filament Transparent Purple is a 1 kg spool of flexible thermoplastic polyurethane (TPU) for FDM/FFF 3D printing. The material features a rubber-like texture with very high elongation at break (≥697%), abrasion and oil resistance, and vivid color, making it suitable for elastic and durable parts such as wearable components and protective covers.

Advantages

The filament combines high flexibility with strong tensile properties and wear resistance, allowing production of parts that bend and recover without damage. It prints stably with low risk of clumping and delivers durable, aesthetically pleasing results when proper settings are used. Pre-made TPU profiles in slicing software help reduce stringing and improve print quality.

Suitable for

• Wearable items (wristbands, straps)
• Phone cases and protective covers
• Vibration dampers and gaskets
• Toy wheels and flexible functional prototypes

When it may not be suitable

This TPU is not ideal for applications requiring rigid, load-bearing structural parts where minimal deformation is critical. It may also be unsuitable for printers that cannot handle flexible filaments or lack appropriate extrusion paths for soft materials.

How to use

Load the filament on a printer that supports TPU and set the nozzle temperature between 195 and 230°C and the build plate to 50–60°C. Use a moderate print speed (50–150 mm/s) and enable TPU-specific profiles in your slicer to reduce stringing. It is recommended to pre-dry the filament and, if required, perform a curing step at 70–80°C for about 8 hours to remove moisture and avoid air bubbles during printing. Use direct drive or a constrained filament path to improve feeding reliability.

What to consider before purchase

• Ensure your 3D printer supports flexible TPU filament and appropriate filament path (direct drive or guided Bowden).
• Check that recommended temperature and speed ranges match your printer capabilities.
• Consider pre-drying equipment if you print in humid conditions.

Usage recommendations

For best results, use printer profiles optimized for TPU, keep extrusion path constrained, pre-dry the filament, and start with conservative retraction and speed settings to minimise stringing and feeding issues.
