TPU FLEX Medium Matt combines all the performance of standard FLEX Medium, 470% extensibility, Shore A98 hardness, and a heat distortion resistance of up to 115°C, with a refined matte surface finish. It's based on Polycaprolactone-Polyester and offers high chemical resistance and extreme layer adhesion, suited to industrial applications where a non-reflective, professional finish matters as much as mechanical performance. The raw material is compliant with REACH and RoHS standards.
Independently tested for UV and weather resistance, holding its colour and integrity through extended outdoor exposure.
Exceptionally strong bonding between layers, even beyond what's typical for flexible filaments.
Genuine toughness against impact and breakage, built for parts that need to survive real-world knocks, not just flex.
A precise, matte surface finish with a professional, technical look and feel.
From standard FDM printers to AMS and multi-material setups, Extrudr filament is built to work reliably with the printer you already own.
From the Austrian Alps, every Extrudr spool is manufactured with care, precision and strict EU standards.
FLEX Medium Matt is compatible with all standard FDM printers on the market.
No. FLEX Medium Matt prints reliably with a standard nozzle.
Yes. FLEX Medium Matt is fully compatible with AMS (Automatic Material System) solutions, including the Bambu Lab AMS.
Yes. FLEX Medium Matt is a hygroscopic material and should be dried before printing to achieve optimal print quality. We recommend drying for 12 hours at 60°C.
FLEX Medium Matt shares the same core performance as standard FLEX Medium, 470% extensibility, Shore A98 hardness, and heat resistance up to 115°C, with the addition of a refined matte surface finish instead of a standard glossy TPU surface.
Yes. FLEX Medium Matt is UV-resistant, making it suitable for outdoor and light-exposed applications.
Yes. FLEX Medium Matt offers high chemical resistance, suited to demanding industrial applications.
No. FLEX Medium Matt is not certified for food contact.
Compliance applies to the raw material, not the finished printed part. Any part intended for a regulated application must undergo separate certification by an accredited third-party laboratory. Requirements vary depending on intended use and applicable standards.
Store FLEX Medium Matt in a dry room at room temperature (18–27°C / 65–80°F). Stored neatly, it is protected from dust and sunlight.
When stored correctly, FLEX Medium Matt has a shelf life of 2 years.
Recommended settings for printers with a 0.4 mm nozzle. Max. 50% layer height. Optimal settings may vary between printers and are also dependent on environmental factors.
Our material profiles make printing easier and more reliable. The profiles are perfectly optimised for Extrudr filaments and deliver perfect results straight away. Simply select your printer and material, import the profile into your slicer, and you’re ready to go.
