## Summary description

c-tech TPU 90A flexible 3D printer filament in signal blue (RAL5005), 1.75 mm diameter, 1 kg spool. Thermoplastic polyurethane (90A hardness) provides high elasticity and abrasion resistance, suitable for printing flexible parts like gaskets, wearable items, and shock-absorbing components. Designed for compatible direct-drive or Bowden extruders with appropriate print settings for TPU.

## Long description

c-tech Flexible TPU 90A is a thermoplastic polyurethane filament in signal blue (RAL5005) with a 1.75 mm diameter on a 1 kg spool. With a Shore hardness of 90A, this TPU combines notable elasticity with strong abrasion resistance, making it suitable for printing flexible and durable parts. The filament is formulated for reliable extrusion on both direct-drive and Bowden systems when correct print settings are applied, and it is intended for users who need resilient functional parts in a vivid blue color.
Advantages
This TPU 90A filament offers a balance of flexibility and toughness: it recovers its shape after deformation, resists wear, and provides dependable layer adhesion when printed with appropriate speeds and temperatures. The 1.75 mm diameter and consistent spool winding support smooth feeding and reduce jams. Signal blue coloration (RAL5005) yields uniform color for visible functional parts or aesthetic components.
Suitable for
 Flexible gaskets, seals, and O-rings
 Wearable items and accessories that require comfort and flexibility
 Shock-absorbing parts, bumpers, and protective covers
 Prototyping flexible mechanisms and hinges
 Small flexible fixtures and custom grips
Key specifications
 Material: Thermoplastic polyurethane (TPU)
 Shore hardness: ~90A (flexible, high resilience)
 Color: Signal blue (RAL5005)
 Filament diameter: 1.75 mm
 Spool weight: 1 kg
 Suitable extrusion systems: Direct-drive and Bowden (with tuned settings)
 Typical properties: High elasticity, abrasion resistance, good layer adhesion
How to use
Load the 1.75 mm filament into a compatible extruder and ensure the printer path is clear to avoid buckling. Select print settings optimized for TPU 90A: use moderate extrusion temperature appropriate for TPU, reduced print speed compared with rigid filaments, and retraction settings adapted for flexible materials (shorter distance or disabled retraction depending on the extruder). A heated bed can improve adhesion; use a suitable build surface or adhesives if needed. Calibrate flow and first-layer height to secure reliable prints and monitor the initial layers for correct extrusion.
Usage recommendations
For best results, print with a direct-drive extruder or tune a Bowden setup for flexible filaments. Use lower print speeds (for example, 15–30 mm/s), adjust retraction to minimize filament stretching, and set extrusion temperatures according to your printer and filament supplier guidelines. Store the filament in a dry environment or sealed container with desiccant to prevent moisture uptake that can affect print quality.
