SainSmart TPU Filament

The filament needs to absorb light energy to glow. Expose your finished prints to direct sunlight or a UV light source for a few minutes to 'charge' the material for the brightest, longest-lasting glow.

Yes, but you must adjust your settings. Because TPU is flexible, it can be tricky in Bowden extruders; we recommend printing slowly at 15-30 mm/s and disabling retraction to prevent jamming.

This filament has a Shore Hardness of 95A. This indicates it is relatively firm for a flexible material, making it easier to print than softer TPUs while still providing excellent durability and elasticity for functional parts like phone cases or gaskets.

Yes, a heated bed is recommended. Setting your platform temperature between 40°C and 60°C will help ensure excellent bed adhesion and minimize the risk of warping during the print.

TPU is hygroscopic, meaning it absorbs moisture from the air, which can cause printing issues. Keep the spool in its vacuum-sealed bag with the included desiccant when you aren't actively using it to maintain print quality.

While the TPU is durable and flexible, keep in mind that the glow effect is a novelty feature that requires regular light exposure. If the part is constantly exposed to harsh outdoor elements, the material's physical properties may degrade over time, just like standard TPU.
