R3D TPU Matte 90A Filament is designed for flexible, durable, and soft-touch 3D-printed parts with a refined matte finish. With high elongation, strong impact performance, and reliable layer bonding, it is ideal for protective components, soft grips, flexible prototypes, anti-slip parts, cushioning designs, and functional elastic applications.
Flexible 90A Feel Provides a soft yet resilient material profile for elastic parts, protective pieces, and flexible functional designs.
Refined Matte Finish creates a lower-gloss surface that gives soft-printed parts a cleaner, more professional appearance.
High Stretch Capacity Offers over 500% elongation at break, making it suitable for prints that need bending, movement, or compression.
Impact-Resistant Performance: Delivers 17kJ/m² impact strength for durable components used in practical everyday applications.
Not Recommended for AMS: Designed for direct-drive or flexible-filament-compatible feeding systems; AMS use is not recommended according to the TDS.
Printing Tips

For best results, print with a flexible-filament-compatible extruder and keep the filament path stable. Slower speeds and careful retraction settings can help reduce feeding issues. Dry the filament before printing if it has absorbed moisture.
FAQs
Q1: What is TPU Matte 90A best used for?
A: TPU Matte 90A is suitable for flexible prototypes, soft grips, protective parts, anti-slip pads, cushioning designs, wearable-style accessories, and functional elastic components.
Q2: How flexible is TPU Matte 90A?
A: It has a 90A flexible material profile and offers over 500% elongation at break, making it suitable for parts that need bending, compression, or repeated movement.
Q3: Is this filament compatible with AMS systems?
A: No. TPU Matte 90A is not AMS compatible. Use a direct-drive or flexible-filament-compatible feeding setup instead.
Q4: Is TPU Matte 90A easy to print?
A: It requires more care than PLA or PETG. A flexible-filament-friendly extruder, stable filament path, controlled speed, and proper retraction settings are recommended.
Q5: Should I dry TPU Matte 90A before printing?
A: If the filament has absorbed moisture, drying at 70°C for 8 hours is recommended before printing.
