PETG prints great on the Elegoo Neptune 4
Keep the spool dryMaterial
PETG soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 60-70 °C for 4-6 h and store it sealed with desiccant.
Buying the CF version of PETG?
Carbon-fiber filament sands down the Elegoo Neptune 4’s stock nozzle. Plain PETG is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
Nothing special neededPrinter
The Elegoo Neptune 4 handles PETG without extra equipment. Load it and print.
