Amolen - Rainbow TPU Filament 1.75mm (95A) - 1kg / 2.2lbs

Amolen Rainbow TPU Filament combines flexible, high-elasticity performance with a seamless multi-color gradient shift. Designed for durable and stretchable 3D prints, this high-grade thermoplastic polyurethane offers outstanding abrasion resistance and shock absorption—making it ideal for flexible phone cases, gaskets, RC parts, footwear components, and vibrant artistic models.

Key Features

• Continuous Rainbow Gradient: Smooth multi-color transitions along the strand create dynamic color shifts throughout your print.
• High Elastic Recovery: Excellent flexibility allows prints to stretch and flex under pressure while returning to their original shape.
• High Abrasion & Impact Resistance: Tough, resilient material resists wear, tear, and mechanical stress.
• Tunable Hardness: Easily adjust infill density and wall layers during slicing to achieve softer or firmer structural effects.
• U.S.-Sourced Quality: Formulated with premium, eco-friendly raw materials and shipped in reusable vacuum-sealed bags with desiccant to protect against moisture.
