Before you print
1 thing to know about this spoolPrint inside an enclosure
It cools too fast in open air and can warp or crack. A closed-in printer holds the heat around the print (chamber at least 18°C).
New here? Nozzle = printing temperature in your slicer, bed = build plate. Start at the big number.
- Nozzle is the hot-end temperature: enter it as the printing temperature in your slicer. Start at the big number; the range is the safe window to tune within.
- Bed is the heated build plate: your slicer calls it bed temperature. It helps prints stick.
- OFD is the Open Filament Database, the community-maintained database this catalog is built on.

Editorial notesUpdated 2026-05-10
Prusa publishes per-spool quality-control data on the label (scan the QR code). The tolerance consistency makes a measurable difference on flow-sensitive prints like flexible joints or fine text. Costs more per kg than generic PLA, but the reliability is worth it on long prints you can't afford to restart.
