Spectrum S-Flex 90A TPU 3D Filament 1,75mm Tiefschwarz 0,5kg

Flexible TPU filament with Shore hardness 90A delivers exceptional elasticity and durability for demanding 3D printing applications. This deep black S-Flex material combines high impact resistance with excellent interlayer adhesion, enabling the production of functional parts that withstand repeated bending and compression.

Advantages

Engineered for reliability, this filament offers consistent diameter (±0.05 mm) and low shrinkage, ensuring precise prints with minimal warping. Its moderate moisture absorption and low odor make it user-friendly, while the vacuum-sealed packaging with desiccant preserves material quality over time.

Suitable for

• Flexible seals and gaskets
• Vibration dampeners and protective cases
• Footwear components and wearable devices
• Phone cases and impact-resistant parts
