    "A score-7 comment says to despool the filament and weigh it, and that a small amount can still feed without the spool. The other method in that comment is to count the loops, measure the circumference, and estimate the remaining length. Neither method needs a guessed tare.",
    "Subtract an empty-spool weight only when it is the weight for that exact spool. The four figures above are four product pages. A PETG HF tare is not a PLA Basic tare. PLA Basic's record does not store an empty-spool weight.",
    "Filament weight on the label, often 1 kg on these ELEGOO pages, is the plastic, not the spool plus plastic. Remaining plastic is the scale reading minus the published empty weight, when you have one."

    "The four tares are the manufacturer pages whose provenance names the empty-spool field.",
    "The comment gives a method that works when the maker has not published a tare."

  "cons": [
    "Most catalog rows are not on this list. An imported number without that provenance field is not treated as a tare."

  "community": "The editorial summary says to weigh the spool and subtract an empty-spool weight, and it offers one gram band for every brand. The method matches the score-7 comment only in part. That comment says to despool and weigh, or to count loops. It does not name an empty-spool weight. r/functionalprint 132shn4, score 65, is about a tall mannequin. Score 38 is a joke. r/3Dprinting uvcohe, score 60, says layer bond is the weak point in that orientation. r/BambuLab 1vj2lwj, score 7, says to despool the filament and weigh it, that a small quantity can be fed without the spool, or to count the loops, measure the circumference, and estimate the remaining length.

      "a": "No. The manufacturer-attributed figures in this catalog are 154 ± 10 g on ELEGOO PETG HF, PETG Glitter, and ASA-CF, and 165 ± 5 g on ELEGOO TPU 72D, from the US pages cited on those rows, catalog citation checked 17 October 2026. A different brand needs its own published tare, or a scale. [Runout](/answers/filament_runout) is what the printer does when the plastic runs out. [Dimensional accuracy](/answers/dimensional) is diameter, not remaining mass."
