  "printerConsiderations": [
    "Neptune 4, 4 Pro, 4 Plus, and 4 Max each say ABS and ASA should be used with an enclosure. That is Elegoo's tip. It is not a chamber temperature.",
    "Elegoo ABS in the catalog is 240–280 °C (464–536 °F) and a bed of 90–100 °C (194–212 °F). The nozzle top is above the Neptune 3 ceiling of 260 °C (500 °F). The bed top is above the 4 Max bed of 85 °C (185 °F). Elegoo ASA is 240–270 °C (464–518 °F) and a bed of 90–100 °C (194–212 °F), with the same two mismatches.",
    "Other open-printer ceilings are [Kobra](/answers/kobra_filament), [K1 and Ender-3 V3](/answers/k1_filament), [the original Ender-3](/answers/ender_filament), and [the A1](/answers/a1_filament). Elegoo filament as a brand is [Elegoo filament](/answers/brand_elegoo)."
  ],
  "pros": [
    "Each ceiling is copied from the Elegoo page for that model, and the Neptune 3 trio is kept as one published pair.",
    "PLA and TPU 95A catalog bands sit inside every ceiling on this page."
  ],
  "cons": [
    "A material name on the Neptune 4 page is not a nozzle profile for a specific spool.",
    "No Neptune 2 ceiling is stated here, because these pages do not give one."
  ],
  "community": "A comment says ASA on a Neptune 4 needs a warm enclosure for anything larger than a trinket. Another says cooling an ASA print too fast can stress it until it breaks. A third says dry ASA on a Neptune 4 Plus was tough, and that brittle ASA had been wet filament.",
