Cautions for Use 

Must dry out before use

Compatible only with H3C
 
Note: Please read the printing guide on Wiki carefully before purchase to ensure the best printing experience and understand the requirements.

Ultra-soft cushioning, made for what touches you.

At 75A, this is one of the softest flexible materials you can print on any FFF 3D printer. Cushioning and flexibility this good finally makes 3D-printed wearables more than a novelty. Print shoes you'd actually wear all day. Print watch bands that feel like a second skin.

2.85 mm filament. Fast and reliable TPU printing, finally.

The FlexFeed extruder takes 2.85 mm filament—a genuine solution that makes high-speed printing of ultra-soft flexibles genuinely reliable. Paired with 75A TPU, FlexFeed pushes the volumetric flow rate to 10 mm³/s — roughly 3× what a conventional 1.75 mm setup can achieve, and without the reliability trade-off.
*Based on internal laboratory testing under specified conditions. Results may vary by printer configuration and print settings.

A natural matte finish — soft to look at, softer to touch.

Most TPU filaments print with an oily sheen that makes the result feel plastic. We retuned this 75A TPU from the ground up to deliver a natural matte finish — with a smooth, skin-like texture that feels as premium as it looks.

Built to take a beating.

You'll use this to print things that get worn, bent, scratched, and squished every day—wearables, cushioning, functional parts.

2.Drying Recommendations

Dry before use to ensure the best print quality and consistent finish. Store in a dry environment after use. To avoid spool deformation that may prevent it from fitting into the dry box, please use a large dry box. 

3. Printing Tips

When printing with TPU 75A, Please set the Flow Dynamics Calibration to Auto.

Do not insert TPU 75A filament directly into the AMS feed inlet, as this may cause damage to the machine. 

TPU 75A supports multi-material printing with filaments other than PLA and PETG. 

4. Safety Tips

Please store the filament in a cool, dark, and dry environment away from direct sunlight and high temperatures.

Please keep filament and any broken fragments out of reach of infants, children, and pets to prevent swallowing or choking.

For opened filament, we recommend drying before use according to the wiki’s recommended temperature and time settings.

Please print this filament in a well-ventilated area, or install an effective air filtration or exhaust system.

As this filament is not food-grade, please avoid using finished prints for food storage or contact.

As this filament is highly moisture-absorbent, please place any unused filament in a sealed container with desiccant immediately, and dry thoroughly before printing.
