  "useCaseLabel": "Prusa",
  "updated": "2026-10-17",
  "shortAnswer": "The catalog stores the Prusa MK4S and the CORE One+ at a 290 °C (554 °F) nozzle and a 120 °C (248 °F) bed. Prusament PLA, PETG, and ASA fit those maxima. The catalog has no Prusa Mini record and no separate original-MK4 record.",

  "printerConsiderations": [
    "The MK4S product page lists a 290 °C (554 °F) maximum nozzle, a 120 °C (248 °F) maximum heatbed, a Nextruder direct drive, a brass CHT nozzle, and an enclosure that is not included. Hardened nozzle is false on the record.",
    "The CORE One+ product page lists the same 290 °C (554 °F) and 120 °C (248 °F) maxima, a heated enclosed chamber, a brass CHT nozzle, and MMU3 support. An HT hotend rated to 400 °C (752 °F) is described there as coming soon. The stored maximum stays 290 °C (554 °F).",
    "Prusament PA11-CF lists 275–295 °C (527–563 °F), so the top of that nozzle is above both printers, and hardened nozzle is true on that filament. The printer records store brass."
  ],
  "pros": [
    "PLA, PETG, and ASA are checked against the stored printer maxima instead of a forum material list.",
    "The PETG warping comments stay on the MK4 thread. They are not written into the PETG datasheet."
  ],
  "cons": [
    "The threads say MK4, MK4/S, Core One, and Core One+. The catalog rows are MK4S and CORE One+ only.",
    "There is no Prusa Mini in the printer table, so this page has no Mini nozzle or bed maximum to publish."
  ],
  "community": "r/prusa3d 197ialb is MK4 PETG warping. The leading comment says PETG and brims go together, asks for an extra -0.05 of squish on the MK4 textured sheet, and says scrub the sheet with a soap degreaser and then isopropyl. Another comment asks about room temperature and drafts. A third says enclose four sides and leave the top open if a vent is blowing. r/prusa3d 1ilu19b asks why a CORE One absorbs heat for about 7:40 before PETG when an MK4/S does not. The leading comment says an unenclosed MK4 has only the room to heat. Another says the gcode is waiting on a chamber temperature. r/prusa3d 1im3lgv asks whether a CORE One should skip PLA for PETG. A comment says the CORE One can print from PC to ASA to PA and that PLA is the easiest start. r/prusa3d 1q8oppv is a CORE One+ filament-detector path, a PTFE tube squeezed by a protrusion. r/prusa3d 19cqtp2 is MK4 filament-sensor complaints. One reply prints 1 kg spools of SUNLU PLA and reports no sensor trouble.",

      "q": "What about the Prusa Mini?",
      "a": "The printer table has the MK4S, the CORE One+, and the XL. It has no Mini row, so this page does not publish a Mini maximum. The MK4S and CORE One+ pages are the stored limits, both 290 °C (554 °F) and 120 °C (248 °F)."
