Unlock the power of ultra-flexible, durable prints with TPU 90A — a filament designed for creators who demand both flexibility and structure. Whether you're crafting shoe soles, RC tires, custom grips, or multi-material prototypes, this filament delivers an exceptional combination of elasticity, wear resistance, and compatibility with rigid materials. With built-in support for beam-interlocking with PLA and PETG (on supported dual-nozzle machines), TPU 90A opens up a world of creative possibilities.
Product Features:
Perfect balance of softness & strength: At 90A hardness, this filament offers impressive flexibility while holding its shape under load — ideal for functional, wearable, or impact-absorbing parts.
Multi-material friendly: Seamlessly pairs with PLA and PETG via structural interlocks in multi-nozzle systems (e.g., H2D), letting you combine rigid and soft elements in one print.
Superior wear resistance: Engineered for repeated flexing and bending, making it perfect for high-demand applications like hinges, cushions, or protective covers.
Ready for creative colour effects: Includes specialized variants like "Blaze" and "Frozen" with gradient effects that appear once per spool for unique style elements.

Colour-Rich designs where the soft gradient effect adds aesthetic value
Printing & Storage Tips:
Dry your filament: TPU 90A is moisture-sensitive; dry at ~70 °C for 8 hours and store sealed with desiccants.
Use recommended nozzle sizes: 0.4 mm / 0.6 mm / 0.8 mm are supported; avoid 0.2 mm nozzles for best reliability.
Adhesion is key: Use glue stick or adhesive on a PEI build plate to avoid warping.
Keep speed moderate: While engineered for performance, best prints occur under ~200 mm/s; pushing beyond may affect quality.
Not AMS compatible: Note that TPU 90A is not compatible with AMS / AMS Lite systems.
When you need more than just a typical flexible filament, TPU 90A rises above. It offers the durability of a tougher polymer with the move-and-flex behavior of a true elastomer. Perfect for functional prints, advanced hybrid prints, and designs that need to move, absorb, and perform. Bring your most demanding flexible parts to life — with precision, reliability, and creative flair.
