eSUN Antibacterial TPU Filament Natural 1.75mm

For optimal results, print eSUN Antibacterial TPU at 220-250°C with a heated bed between 45-60°C. A fan speed of 100% and travel speed of 50-100 mm/s are recommended. Ensure good bed adhesion using an adhesive or texture, and print slowly to prevent stringing and ensure strong layer bonding.

The eSUN Antibacterial TPU is formulated with an upgraded polymer that actively inhibits the growth of bacteria such as Escherichia coli and Staphylococcus aureus, achieving 99.9% efficacy. It also boasts a Grade 0 antifungal rating, preventing mildew and maintaining hygiene for sensitive applications by integrating these agents directly into the material's matrix.

This filament is ideal for applications requiring both flexibility and high hygiene. Common uses include medical accessories like splints and prostheses, sanitary contact items such as mask holders and door openers, and any functional parts for home or public spaces where bacterial and fungal resistance is critical for health and longevity.

A 95 Shore A hardness indicates a robust yet flexible material. It's harder than typical highly flexible filaments, providing excellent impact resistance and enhanced durability rather than extreme pliability. This balance makes it superb for components that need to withstand significant stress, absorb shock, and maintain their shape while still offering some give.

Like most TPU filaments, eSUN Antibacterial TPU is hygroscopic, meaning it absorbs moisture from the air. For best print quality and to prevent issues like stringing or poor layer adhesion, it's highly recommended to dry the filament before use. A typical drying regimen involves heating it at 50-60°C for 6-12 hours in a filament dryer.
