Before you print

3 things to know about this spool

Dry it before you print
It quietly soaks up moisture from the air, which leaves prints rough, weak and stringy. Dry it first, then keep it sealed.
Print 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.
Needs a high-temperature hotend
It runs hotter than everyday filaments. Check your printer can reach its nozzle temperature before you buy.

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 source this spec sheet comes from.
