    "PolyLite PETG's bed stops at 90 °C (194 °F). PolyLite ABS starts at 90 °C (194 °F) and runs to 110 °C (230 °F). A PETG bed is not an ABS bed.",
    "The HDT pairs above are the same brand, the same standard, and both loads. A higher HDT is not a strength ranking and not a UV ranking.",
    "Enclosure required is blank on these three rows. Whether ABS needs a box is [ABS printing](/answers/abs_print), not a number this sheet comparison invents."
  ],
  "pros": [
    "The heat numbers are one manufacturer's ISO 75 pairs, so the load is stated both times.",
    "The comment that prefers PETG on a P1S is kept as a comment. It is not rewritten as a Polymaker result."
  ],
  "cons": [
    "lists ABS as cheaper, easier to sand, faster, and stronger. None of those four words is a cell on these sheets.",
    "Acetone vapor smoothing is named in that same comment. It is not a procedure on this page."
  ],
  "community": "The editorial summary says PETG is easier and needs no enclosure, and that ABS is more heat resistant and can be smoothed. The heat-deflection rows support a higher ABS and ASA number. They do not say easier. r/BambuLab 156myl5, score 16, lists ABS as cheaper, easy to sand, acetone-smoothable, faster, more temperature resistant, and stronger, and then the excerpt cuts off at impact resistance. r/BambuLab 1q2bvip, score 9, says ABS was a pain and layer adhesion was poor, and that PA and PC worked better for that person when an enclosure was required. Score 4 says PETG is significantly easier than the few Bambu ABS prints they made on a P1S, if the application allows PETG. r/3Dprinting uoaa03, score 4, names Prusament PETG Prusa Orange and Atomic Filaments Perfect Orange Opaque PETG PRO as color options. No excerpt was supplied for r/FixMyPrint 1jfyujf or r/3Dprinting wts1am.",

      "a": "On these three PolyLite sheets, ABS and ASA deflect at a higher temperature than PETG, at both 0.45 MPa and 1.8 MPa. PETG prints at 220–250 °C (428–482 °F) with a bed of 70–90 °C (158–194 °F). ABS prints at 230–260 °C (446–500 °F) with a bed of 90–110 °C (194–230 °F). [Heat resistance](/answers/heat) is the temperature page. [PLA versus PETG](/answers/pla_vs_petg) is the other material pair. Better depends on which of those limits you actually hit."
