    "That title is not the Bambu sheet. The sheet's blast oven is 80 °C (176 °F) for 8–12 h, and its X1 heatbed method is 90–100 °C (194–212 °F) for 12 h."

  "pros": [
    "Water solubility is quoted from the sheets. The missing clock and the missing water temperature stay missing.",

  "cons": [
    "No price is stored on these rows. That word is not a figure here.",
    "The highest-scored comments are about a print that looks like it is burning. They are not a dissolve procedure."

  "community": "The editorial summary says PVA dissolves in water, must be dried thoroughly, and is expensive and hygroscopic. Dissolves in water matches the sheets. Expensive does not appear as a price. r/FixMyPrint vvclbq, score 47, asks why the print looks like magma. Score 5 asks if it is printing dangerously hot and says to shut it down if it is burning. The excerpt is cut off. r/BambuLab 109ubyx, score 4, says there are good and bad brands and heavily cautions using dissolvable supports on an MMU because of contamination. The excerpt is cut off mid-word. Score 3 says that person uses breakaway support for basic prints and PVA for challenging geometry, that PVA which has been sitting must be dried, and that dry PVA can print in the AMS. The excerpt is cut off after that. No excerpt was supplied for r/prusa3d 17ivx7t, r/3Dprinting ug5myk, or r/BambuLab 1ggy3oi.",
