  "slug": "abs_enclosure",
  "useCase": "abs",
  "useCaseLabel": "ABS",
  "updated": "2026-10-17",
  "shortAnswer": "An enclosure helps ABS and ASA only when the air inside it is hot. A closed MK3 at 36 degrees still warped ASA, and ABS still split layers inside an enclosure when the comments said the chamber itself was too cool.",

    "On r/3Dprinting vvtizp the ABS print was already in an enclosure at a 105 °C (221 °F) bed, a 250 °C (482 °F) nozzle, 0.5 mm layers, a 1 mm CHT nozzle, and 120 mm/s, and the layers still separated. A score-58 comment says heat the enclosure to 70 °C (158 °F). A score-16 comment says drop the layer to about 0.2 mm or slow down.",
    "On r/prusa3d 17d5ku8 an MK3 enclosure at 36 degrees warped ASA the same way the open printer did. The leading comment says clean the plate with isopropyl, use the highest bed the printer allows, preheat the chamber at least 15 minutes with the bed, and turn the part fan off. A score-17 comment calls 36 degrees way too low, starts ASA at at least 45 degrees, and sees the chamber settle at 55, with the electronics outside the box.",
    "The MK4S record stores an optional enclosure. The CORE One+ record stores a heated enclosed chamber. Both store a 290 °C (554 °F) nozzle and a 120 °C (248 °F) bed. Neither filament row below fills in enclosure required."
  ],
  "pros": [
    "The chamber figures stay attached to the comments that wrote them. 70 °C (158 °F) is one ABS comment. 45 degrees and 55 are one ASA comment.",
    "The catalog beds are 90–110 °C (194–230 °F) or 100–120 °C (212–248 °F), so a 105 °C (221 °F) bed can be inside one row and still not be a chamber temperature."
  ],
  "cons": [
    "Enclosure required is blank on eSUN ABS+, PolyLite ASA, and Prusament ASA. The first sentence is the thread evidence, not a filled catalog cell.",
    "r/prusa3d 1107u40 is about printing enclosure parts in PLA. It is not a test of printing ABS."

  "community": "r/3Dprinting vvtizp is ABS layer separation inside an enclosure at 105 °C (221 °F) bed and 250 °C (482 °F) nozzle. The leading comment says heat the enclosure to 70 °C (158 °F). Another says the layer is too tall at 0.5 mm. r/prusa3d 17d5ku8 is ASA warping in an MK3 enclosure at 36 degrees, the same warp as with no enclosure. The tips comment wants isopropyl, the highest bed, a 15 minute preheat, and the part fan off. Another comment wants at least 45 degrees and sees 55 later. r/3Dprinting zp4gz5 is ABS in an enclosure outdoors with poor layer adhesion. A score-35 comment says the enclosure has to raise the ambient temperature, and a cold day outside lowers it. A score-25 comment says the enclosure needs to be a minimum of 20–30 °C (68–86 °F) and that 40 °F outside is unlikely to work. r/prusa3d 1107u40 asks about Polymaker PLA Pro for Lack-enclosure parts that the instructions want in PETG. A comment printed those parts in PLA and reports three years with no issues, and says the parts are not above 100 °F or under much load. r/3Dprinting 1rzvg8o asks for an enclosed printer that does not lock filament. A comment points at Prusa.",

Both list a 290 °C (554 °F) nozzle and a 120 °C (248 °F) bed. Prusament ASA lists a bed of 100–120 °C (212–248 °F), so the top of that bed matches the printer maximum."
