KLEMA TPU90A 1.75 mm 1 kg Black is a TPU filament for printing flexible cases and protective housings. In a batch like this, every part is stretched repeatedly by hand. The material must therefore resist tearing and keep its appearance over time. A narrow diameter tolerance ensures uniform extrusion.
Key features and benefits
- Filament diameter: 1.75 ± 0.02 mm — A tightly controlled tolerance ensures uniform extrusion and improves print accuracy.
- Tensile strength: 40±6 MPa — Functional parts withstand stretching without tearing.
- Nozzle temperature: 220–240 °C — Set this range in the slicer profile before the first print.
- Print speed: ≤40 mm/s — The retraction speed also does not exceed 40 mm/s, and the retraction distance is 0.8 mm.
- Tear resistance: the printed parts are flexible and do not tear when stretched, which suits functional models requiring high toughness.
- Ageing resistance: high stability against environmental influences preserves properties and appearance during long-term use, and the service life of the part is longer.
- Low shrinkage: 0.1–0.3 % — the part geometry deviates minimally after cooling.
Applications
Functional models work under tension and bending. KLEMA TPU90A 1.75 mm 1 kg Black provides flexibility and tear resistance. The part does not tear.

Ageing resistance determines the service life of the part. The material preserves its properties and appearance during prolonged use. This is important for cases that are picked up every day.

The diameter tolerance is tightly controlled. This ensures smooth extrusion and improves compatibility with printers. For flexible filament, limit the print and retraction speed to 40 mm/s.

- Smartphone cases: the material does not tear when pulled onto the body, and ageing resistance preserves its appearance with everyday use.
- Sports equipment: a tensile strength of 40±6 MPa allows you to print lattice balls that keep their integrity under impact.
- Flexible prototype assemblies: a flexural strength of 65±6 MPa suits parts that bend repeatedly.
- Outdoor items: ageing resistance preserves properties, but a heat deflection temperature of 55±5 °C sets the heating limit.
- Batch printing: a diameter tolerance of ±0.02 mm gives uniform extrusion from spool to spool.
