Frequently asked questions
What filaments can the Neptune 2D print?
The Elegoo Neptune 2D has slicer profiles for 6 filament types: PLA, PETG, ASA, PLA+, ABS, and 1 more. As an open-frame printer, it excels with PLA and PETG — ABS and ASA require careful setup without an enclosure.
Can the Neptune 2D print ABS?
The Elegoo Neptune 2D is an open-frame printer, which makes ABS challenging — ABS warps significantly without an enclosed print environment. For ABS on an open machine, use a 100–110°C bed, disable the fan completely, add a cardboard or acrylic enclosure, and limit print size. For most users, ASA or PETG are better alternatives on open-frame printers.
Does the Neptune 2D need an all-metal hot end?
The Elegoo Neptune 2D has a maximum nozzle temperature of 300°C, which requires an all-metal hot end. Standard PTFE-lined hot ends are safe up to about 240°C — above that, PTFE degrades and can release fumes. At 300°C, an all-metal hot end is required for safe high-temperature printing of Nylon, PC, and composites.
