Product description

Printing Tips:

Enable Retraction: Always enable retraction settings to prevent stringing.Printing Speed: Print slowly (<150 mm/s) to avoid stringing and maintain quality.Extruder: Use a direct drive extruder and set the temperature to 200-220°C.Bed Adhesion: To prevent warping, use a heated bed set to 30-55°C, and consider using adhesive aids like glue sticks or painter’s tape.Test Print: Adjust retraction speed and distance, as even small changes can impact print quality.Cooling Fan: Adjust the fan speed based on your printing speed to ensure proper cooling.Storage: Store in a sealed container with desiccant to keep it dry.

1. Can it be used with a Bowden tube setup?

Yes, SainSmart TPU is flexible but designed to print smoothly on both Bowden and direct drive extruders. Its clog-free formulation helps reduce feeding issues common with flexible filaments in Bowden setups.

2. Does it require a heated print bed?

While a heated bed is not strictly required, we recommend using one set around 30–55°C to improve adhesion and reduce warping during printing.

3. Is it prone to warping or curling?

TPU generally has low warping compared to rigid filaments. With proper bed adhesion and printing at the recommended temperature (220–240°C), warping and curling are minimal.

Flexible TPU: Create robust and flexible parts with ease using SainSmart TPU filament. Its Shore Hardness of 95A ensures your prints are tough and bendable, perfect for various projects such as shoe insoles, watch bands, phone cases, and drone parts, etc.
