    Choosing filament for the Elegoo Neptune 4 Max

    The Elegoo Neptune 4 Max has hotend up to 300°C, bed up to 85°C, an open frame and a brass nozzle as standard. That decides which filaments it prints well as it comes, and which need an upgrade first.

    Out of the box it handles PLA, PETG and TPU. The lists below are the cheapest of each in stock on Amazon UK and Eryone UK right now, sorted by price per kilogram and filtered to the right diameter.

    ABS needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C.

    ABS-CF needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C.

    ASA needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C.

    PC needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C.

    ABS, ABS-CF, ASA, Nylon and PC warp and split in a draught, so on an open-frame printer like the Elegoo Neptune 4 Max they need an enclosure.

    PLA Glow, PLA-CF, PETG-CF and ABS-CF are abrasive and wear out the brass nozzle the Elegoo Neptune 4 Max comes with; fit a hardened steel nozzle first.

    An enclosure or a draught-free room helps with larger PETG prints.

    Temperatures are typical starting points from manufacturers' data sheets. The range printed on the reel always wins, because it varies between brands and colours.

    Common questions

    What is the best filament for the Elegoo Neptune 4 Max?

    PLA for most prints: it prints on the Elegoo Neptune 4 Max as it comes, barely warps and is the cheapest to buy (the cheapest reel in stock on Amazon UK and Eryone UK is £7.12/kg right now). For parts that need more strength, heat resistance or flex, it also prints PETG and TPU without upgrades.

    Can the Elegoo Neptune 4 Max print ABS?

    Not as it comes. ABS needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C. ABS warps and splits in a draught; the Elegoo Neptune 4 Max is an open-frame printer, so it needs an enclosure.

    Can the Elegoo Neptune 4 Max print ASA?

    Not as it comes. ASA needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C. ASA warps and splits in a draught; the Elegoo Neptune 4 Max is an open-frame printer, so it needs an enclosure.

    Can the Elegoo Neptune 4 Max print PETG?

    Yes. PETG prints on the Elegoo Neptune 4 Max as it comes: set the nozzle to 230-260°C and the bed to 65-85°C. An enclosure or a draught-free room helps with larger PETG prints.

    Can the Elegoo Neptune 4 Max print TPU?

    Yes. TPU prints on the Elegoo Neptune 4 Max as it comes: set the nozzle to 210-240°C and the bed to 30-50°C.

    Can the Elegoo Neptune 4 Max print Nylon?

    Not as it comes. Nylon warps and splits in a draught; the Elegoo Neptune 4 Max is an open-frame printer, so it needs an enclosure.

    Can the Elegoo Neptune 4 Max print PC?

    Not as it comes. PC needs a bed of at least 90°C; the Elegoo Neptune 4 Max reaches 85°C. PC warps and splits in a draught; the Elegoo Neptune 4 Max is an open-frame printer, so it needs an enclosure.

    Can the Elegoo Neptune 4 Max print carbon fibre filament?

    Only after fitting a hardened steel nozzle. Carbon fibre, glass fibre and glow-in-the-dark filaments quickly wear out the brass nozzle it comes with.

    Do I need a filament dryer for the Elegoo Neptune 4 Max?

    Not for PLA, but TPU soaks up moisture from the air and print stringy and weak when wet. A dryer that reaches 70°C covers it; the drying chart has the time for each.

    How big can the Elegoo Neptune 4 Max print?

    Up to 420 × 420 × 480 mm. For a big print, check the slicer's filament estimate against what is left on the reel before you start.
