    "Three makers, three beds. SUNLU writes 50–60 °C (122–140 °F) with glue. Fiberlogy says the bed is not required with packing tape. Prusament writes 95 ± 10 °C (203 ± 18 °F) on a PP sheet or PP tape. A shared polypropylene profile would mis-state all three.",
    "SUNLU's page also says an enclosed chamber to limit warping, and part fan at 10%. Fiberlogy's page says an enclosed chamber is not required, and airflow 0–50%. Prusament's page says enclosure not required for the glass-filled grade. Those are three sentences, not one rule.",
    "The catalog still shows SUNLU's bed as blank and Fiberlogy's nozzle as 210–240 °C (410–464 °F). The sentences above are the pages read on 26 October 2026."

    "and describe a one-layer PP wipe so that PLA sticks later. That is a comment about a sheet, not a SUNLU setting.",
    "A comment says PP warps without chamber temperature and that carbon or glass fiber is what stabilizes it. Prusament's glass-filled page says large models without an enclosure. The comment and the page are both reported. They are not merged."

  "community": "The editorial summary says PP needs a PP build sheet or packing tape and warps heavily. The three product pages do name a PP surface or packing tape. Warp is not a single number. r/prusa3d 1o89sz4, score 83, says a large PETG or PP layer on the sheet makes PLA stick. Score 53 says print a single layer of PP across the sheet, peel it, then print as normal. r/prusa3d 1u5s0fc, score 10, says PP warps without a lot of chamber temperature, and that carbon or glass fiber is what stabilizes the material. Score 3 says Centaur PP on their PP sheet has no problems. No excerpt was supplied for r/BambuLab 146504x, r/BambuLab 17e60j6, or r/prusa3d 1m5jhb9.",
