DuraPro PA12 is a highly functional polyamide (nylon) built for industrial applications. It's characterised by exceptionally high impact and notched impact strength, retaining toughness even at low temperatures, alongside very good heat resistance. Low moisture absorption keeps parts dimensionally stable over time, a genuine advantage of PA12 over other nylon grades, while excellent chemical resistance and easy handling make it a dependable choice for demanding, real-world 3D printing projects.

DuraPro PA12 Highlights
HIGH IMPACT STRENGTH
Retains toughness even at -30°C, with no break in unnotched impact testing at both room and sub-zero temperatures.
LOW MOISTURE ABSORPTION
Just 1.6% water absorption at saturation, significantly lower than other nylon grades, keeping parts dimensionally stable over time.
HIGH HEAT RESISTANCE
Improved thermal performance over the standard blend, holds its shape reliably under serious thermal stress.
GOOD CHEMICAL RESISTANCE
Withstands exposure to a broad range of chemicals, suited to demanding industrial environments.
FITS ANY PRINTER, ANY SYSTEM
From standard FDM printers to AMS and multi-material setups, Extrudr filament is built to work reliably with the printer you already own.
MADE IN AUSTRIA
From the Austrian Alps, every Extrudr spool is manufactured with care, precision and strict EU standards.
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.

PRINTING & COMPATIBILITY
DuraPro PA12 is compatible with all standard FDM printers on the market. Note: an enclosed print space is required, and a heated bed capable of reaching 110°C is recommended, printers without these capabilities may not achieve optimal results.
Yes. DuraPro PA12 is fully compatible with AMS (Automatic Material System) solutions, including the Bambu Lab AMS.
No. DuraPro PA12 prints reliably with a standard nozzle.
Yes. DuraPro PA12 is a hygroscopic material and should be dried before printing to achieve optimal print quality. We recommend drying for 8–12 hours at 65°C.
MATERIAL PROPERTIES
DuraPro PA12 offers significantly lower moisture absorption than PA6-based nylons (1.6% vs. typically around 9-10% at saturation), giving it better long-term dimensional stability. This makes it easier to store and print reliably, with less risk of warping from humidity.
Yes. DuraPro PA12 is suitable for outdoor use.
CERTIFICATION & COMPLIANCE
No. DuraPro PA12 is not suitable for food contact.
CARE & STORAGE
Store DuraPro PA12 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 PA12 has a shelf life of 2 years.
