Choosing filament for the Prusa Core One L
The Prusa Core One L has hotend up to 290°C, bed up to 120°C, a heated enclosure, a brass nozzle as standard and Single material as standard support. That decides which filaments it prints well as it comes, and which need an upgrade first.
Out of the box it handles PLA, PETG, ABS, ASA, Nylon, TPU and PC. The lists below are the cheapest of each in stock on Amazon UK and Eryone UK right now, sorted by price per kilogram and filtered to the right diameter.
PLA Glow, PLA-CF, PETG-CF and ABS-CF are abrasive and wear out the brass nozzle the Prusa Core One L comes with; fit a hardened steel nozzle first.
Temperatures are typical starting points from manufacturers' data sheets. The range printed on the reel always wins, because it varies between brands and colours.
Common questions
What is the best filament for the Prusa Core One L?
PLA for most prints: it prints on the Prusa Core One L as it comes, barely warps and is the cheapest to buy (the cheapest reel in stock on Amazon UK and Eryone UK is £7.12/kg right now). For parts that need more strength, heat resistance or flex, it also prints PETG, ABS, ASA, Nylon, TPU and PC without upgrades.
Can the Prusa Core One L print ABS?
Yes. ABS prints on the Prusa Core One L as it comes: set the nozzle to 240-270°C and the bed to 90-110°C.
Can the Prusa Core One L print ASA?
Yes. ASA prints on the Prusa Core One L as it comes: set the nozzle to 240-270°C and the bed to 90-110°C.
Can the Prusa Core One L print PETG?
Yes. PETG prints on the Prusa Core One L as it comes: set the nozzle to 230-260°C and the bed to 65-85°C.
Can the Prusa Core One L print TPU?
Yes. TPU prints on the Prusa Core One L as it comes: set the nozzle to 210-240°C and the bed to 30-50°C. Flexible filament jams in the Single material as standard; feed it from the external spool holder instead.
Can the Prusa Core One L print Nylon?
Yes. Nylon prints on the Prusa Core One L as it comes: set the nozzle to 240-270°C and the bed to 40-90°C.
Can the Prusa Core One L print PC?
Yes. PC prints on the Prusa Core One L as it comes: set the nozzle to 250-270°C and the bed to 90-105°C.
Can the Prusa Core One L print carbon fibre filament?
Only after fitting a hardened steel nozzle. Carbon fibre, glass fibre and glow-in-the-dark filaments quickly wear out the brass nozzle it comes with.
Do I need a filament dryer for the Prusa Core One L?
Not for PLA, but Nylon and TPU soak up moisture from the air and print stringy and weak when wet. A dryer that reaches 80°C covers all of them; the drying chart has the time for each.
How big can the Prusa Core One L print?
Up to 300 × 300 × 330 mm. For a big print, check the slicer's filament estimate against what is left on the reel before you start.
