What filaments can Elegoo Neptune printers run?

Elegoo's Neptune 4, 4 Pro, 4 Plus, and 4 Max pages list a 300 °C (572 °F) nozzle and name PLA, TPU, PETG, ABS, ASA, and nylon. The hot bed is 110 °C (230 °F) on the 4 and 4 Pro, 100 °C (212 °F) on the 4 Plus, and 85 °C (185 °F) at a 25 °C (77 °F) room on the 4 Max. Elegoo's Neptune 3 comparison gives the Pro, Plus, and Max a 260 °C (500 °F) nozzle and a 100 °C (212 °F) bed, and it does not repeat that six-material line.

Neptune 4, 4 Pro, 4 Plus, and 4 Max

The Neptune 4 and Neptune 4 Pro pages, read 28 October 2026, list a maximum nozzle of 300 °C (572 °F) and a maximum hot bed of 110 °C (230 °F). Filament compatibility on both is PLA, TPU, PETG, ABS, ASA, and nylon. Both say ABS and ASA should be used with an enclosure.

The Neptune 4 Plus lists the same 300 °C (572 °F) nozzle, the same six materials, and the same enclosure tip. Its maximum hot bed is 100 °C (212 °F).

The Neptune 4 Max lists the same 300 °C (572 °F) nozzle, the same six materials, and the same enclosure tip. Its maximum hot bed is 85 °C (185 °F) at an ambient temperature of 25 °C (77 °F). The Max FAQ repeats those two ceilings and says the room should be about 25 °C (77 °F) to reach the bed maximum.

Neptune 3 Pro, Plus, and Max

Elegoo's comparison groups the Neptune 3 Pro, Plus, and Max. It says the bed can be set up to 100 °C (212 °F) and the nozzle up to 260 °C (500 °F), and that the nozzle is suitable for ABS. It says the family is intended for all kinds of filaments, including TPU. It does not publish the Neptune 4 list of PLA, PETG, ABS, ASA, and nylon as a specification table. ASA and nylon are not given a Neptune 3 ceiling on that page.

Spool temperatures next to those ceilings

Elegoo PLA stores 190–230 °C (374–446 °F) and a bed of 35–65 °C (95–149 °F). Elegoo TPU 95A stores 220–240 °C (428–464 °F) and a bed of 30–45 °C (86–113 °F). Both bands sit inside every ceiling above.

Elegoo PETG stores 220–250 °C (428–482 °F) and a bed of 70–90 °C (158–194 °F). The nozzle fits. The 90 °C (194 °F) top of the bed fits the 4, 4 Pro, and 4 Plus, and it is above the 4 Max bed of 85 °C (185 °F). Do not set the Max bed to 90 °C (194 °F) from this catalog cell.

Elegoo ABS stores 240–280 °C (464–536 °F) and a bed of 90–100 °C (194–212 °F). Elegoo ASA stores 240–270 °C (464–518 °F) and a bed of 90–100 °C (194–212 °F). Elegoo names both materials on the Neptune 4 family pages. The catalog nozzle for ABS passes 260 °C (500 °F), so it does not fit the Neptune 3 ceiling as a whole band. Both beds pass 85 °C (185 °F), so they do not fit the 4 Max bed as a whole band.

Kobra filaments, K1 and Ender-3 V3, Ender 3 filaments, and Elegoo as a brand are separate machines and spools.

What the community says

A comment in a Reddit thread in r/ElegooNeptune4 says ASA needs an enclosure for anything larger than a trinket so it does not warp.

A comment in a Reddit thread in r/ElegooNeptune4 says cooling an ASA print too fast after it finishes can stress the part until it breaks.

A comment in a Reddit thread in r/ElegooNeptune4 says brittle ASA was wet filament, and that dry ASA on a Neptune 4 Plus stayed tough without an enclosure.
