What to feed the Elegoo Neptune 4
Best filament for the Neptune 4
ELEGOO's own spools fit naturally: PLA Basic is the budget staple of this printer's whole era, and Rapid PLA+ suits its quicker side.
PETG, the fast way
ELEGOO Rapid PETG is rated to 600 mm/s and runs 240-270 °C, inside this machine's 300 °C reach. Steal one habit from its datasheet: dry PETG at 60 °C for 8 hours before a big print.
ABS and TPU
ABS comes with the usual chores: hot bed, ventilation, no drafts. TPU prints well if you refuse to hurry it.
