Significantly increases rigidity and mechanical strength, so parts resist flexing and hold their shape under load.
Improved thermal performance compared to standard ABS, holds its shape reliably under real thermal stress.
A precise, matte surface finish with a professional, technical look and feel.
Genuinely lighter than standard ABS, without compromising on stiffness or heat resistance.
From the Austrian Alps, every Extrudr spool is manufactured with care, precision and strict EU standards.
From standard FDM printers to AMS and multi-material setups, Extrudr filament is built to work reliably with the printer you already own.
DuraPro ABS CF is compatible with all standard FDM printers on the market. Note: an enclosed print space is required, and a heated bed capable of reaching 100–110°C is recommended.
Yes. DuraPro ABS CF is fully compatible with AMS (Automatic Material System) solutions, including the Bambu Lab AMS.
Yes. As with all carbon-fiber-reinforced materials, the abrasive content will gradually wear down a standard brass nozzle. We recommend a hardened nozzle (e.g., hardened steel or ruby) with a diameter of at least 0.6mm for smooth, reliable extrusion and consistent nozzle lifespan.
DuraPro ABS CF offers greater stiffness and improved heat resistance than standard ABS, thanks to carbon fiber reinforcement, while also being genuinely lighter in weight. As with all carbon-fiber-reinforced materials, this added rigidity comes with reduced elongation at break compared to standard ABS, making it best suited to applications where stiffness matters more than flexibility.
DuraPro ABS CF is not recommended for long-term or permanent outdoor use. Like standard ABS, it is prone to UV degradation, which can cause yellowing, brittleness, and reduced mechanical performance over time. For outdoor applications, consider DuraPro ASA.
Yes. DuraPro ABS CF offers good chemical resistance, suited to demanding technical applications.
No. Carbon fiber reinforced filaments, including DuraPro ABS CF, are not certified for food contact.
DuraPro ABS CF is rated UL 94 HB for flame retardancy.
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 DuraPro ABS CF 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, DuraPro ABS CF 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.
