## Summary description

c-tech TPU 90A is a flexible 1.75 mm 3D printing filament in luminescent green (RAL6038) supplied on a 1 kg spool. With shore hardness 90A it offers medium flexibility and good wear resistance for functional and decorative parts. Suitable for FDM/FFF printers that support TPU, it is ideal for prototypes, seals, wearable items and impact-absorbing components.

## Long description

c-tech Flexible TPU 90A filament in luminescent green (RAL6038) is a 1.75 mm, 1 kg spool of thermoplastic polyurethane designed for FDM/FFF 3D printers that accept flexible materials. With a Shore hardness of 90A this filament provides medium flexibility combined with good wear and abrasion resistance, making it suitable for parts that require elasticity without excessive softness. The luminescent green color (RAL6038) ensures high visibility and distinct appearance for functional prototypes, decorative elements and safety-related components.
Advantages
The filament balances flexibility and dimensional stability, enabling printouts that bend and recover while maintaining shape under load. Its Shore 90A hardness yields durable surfaces resistant to abrasion and repeated mechanical stress. As a 1.75 mm TPU material supplied on a 1 kg spool, it is compatible with most desktop FDM/FFF printers configured for flexible filaments and offers consistent feed and extrusion when print settings are adjusted for elastomers. The luminescent green pigment provides good color saturation and visibility for parts used in low-light environments or to mark components by color.
Suitable for
 Functional prototypes requiring elasticity and wear resistance
 Seals, gaskets and vibration-damping parts
 Wearable items such as straps, bands and soft clips
 Impact-absorbing components and bumpers
 Decorative or safety parts needing high-visibility green
Key specifications
 Material: Thermoplastic polyurethane (TPU), medium-flexible elastomer
 Shore hardness: 90A (medium flexibility)
 Diameter: 1.75 mm nominal
 Spool weight: 1 kg of filament
 Color: Luminescent green (RAL6038)
 Compatibility: FDM/FFF 3D printers that support flexible filaments
How to use
Load the 1.75 mm TPU filament into an FDM/FFF printer prepared for flexible materials, ensuring the filament path is as straight and constrained as possible to avoid buckling. Use a direct-drive extruder or a well-tuned Bowden setup with a short, guided filament path. Typical printing temperatures for TPU are in a moderate range; set nozzle and bed temperatures according to your printer and material behavior, and reduce print speed compared with rigid filaments to improve extrusion control. Enable retraction settings optimized for TPU to minimize stringing, or reduce retraction if grinding occurs. Allow prints to cool sufficiently before post-processing to retain dimensional stability.
Usage recommendations
For best results, print at reduced speeds (e.g., slower than standard PLA/ABS settings), use a lower retraction distance to prevent filament jamming, and choose a build surface that promotes adhesion without making removal difficult. If increased layer adhesion is required, slightly raise nozzle temperature or reduce cooling; if stringing appears, increase retraction slightly or lower print temperature. Store the spool in a dry environment or sealed with desiccant to prevent moisture uptake that can affect print quality.
