SainSmart TPU Filament

While it can work with various setups, a direct drive extruder is highly recommended for this filament. Bowden setups can sometimes struggle with flexible materials like TPU due to the distance between the extruder and the hotend, which can lead to jamming.

This filament has a Shore Hardness of 95A. This means it offers a balance of durability and flexibility, making it firm enough to hold its shape for functional parts like gaskets or phone cases, while still providing a noticeable rubber-like give.

Yes, this filament is designed for broad compatibility with most standard FDM printers that accept 1.75mm diameter material. Just ensure your printer settings are adjusted to the recommended temperature range of 195–230°C.

TPU is hygroscopic, meaning it absorbs moisture from the air, which can ruin print quality. Keep the spool in its original vacuum-sealed bag with the included desiccant when not in use, or store it in a dry box or airtight container.

Start with an extruder temperature between 195°C and 230°C and a heated bed set to 40–60°C. Because TPU is flexible, you may also need to adjust your retraction settings—often slowing down your print speed significantly helps prevent clogging and stringing.

Yes, this filament is manufactured with a dimensional accuracy of +/- 0.05 mm. This consistency helps ensure a smooth, reliable extrusion process, which is critical for maintaining the structural integrity of your prints.
