ABS on the Elegoo Neptune 4
Yes, but it takes extra gear or care. Open budget machine with a big following and Klipper speed.
ABS is tricky on the Elegoo Neptune 4
No enclosure on this printerPrinter
The Elegoo Neptune 4 is open to the room, and ABS warps and cracks in open air. Small parts can survive; for anything bigger, add an enclosure (even a grow tent or a box over the printer helps).
Fumes: give it fresh airMaterial
ABS gives off unpleasant fumes while printing. Run it in a ventilated room you are not sitting in, or vent the printer outside.
Buying the CF version of ABS?
Carbon-fiber filament sands down the Elegoo Neptune 4’s stock nozzle. Plain ABS is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
Safe starting ranges for ABS as a family, not gospel. Each spool below has its exact manufacturer numbers, the dated source, and one-click slicer settings on its page.
