How much filament is left on a spool / spool weights?

Remaining filament is a scale problem. If you can take the plastic off the spool, the scale reads the plastic. If you cannot, you need an empty-spool weight that the maker published for that spool, then subtract it from the weight of the spool you still have. Runout is the printer stopping. Dimensional accuracy is diameter and shrinkage. Neither page is a tare chart.

The four published empty-spool weights

These are the catalog rows whose provenance names `emptySpoolWeightsG` on a manufacturer page. The table order is the order those records were written, not a quality ranking.

ELEGOO PETG HF lists 230–260 °C (446–500 °F), a bed of 65–75 °C (149–167 °F), and drying at 60 °C (140 °F) for 8 h. The FAQ states an empty spool weight of 154 ± 10 g on a 1 kg spool. ELEGOO PETG Glitter lists 240–260 °C (464–500 °F), a bed of 65–75 °C (149–167 °F), and drying at 60 °C (140 °F) for 8 h, with the same 154 ± 10 g empty spool on a 1 kg spool. ELEGOO ASA-CF lists 250–280 °C (482–536 °F) and a bed of 90–100 °C (194–212 °F), and the FAQ states 154 ± 10 g empty on a 1 kg spool. The checked note on that row records a drying conflict, 80 ± 5 °C (176 ± 9 °F) for 8 h on the spec table and 85 °C (185 °F) for 8 h in the description, so no drying figure is repeated here. ELEGOO TPU 72D lists 210–240 °C (410–464 °F), a bed of 30–45 °C (86–113 °F), drying at 70 °C (158 °F) for 8 h, and Shore 72D. The FAQ and the checked note state an empty spool weight of 165 ± 5 g on a 1 kg spool. Each citation dates the US page check as 17 October 2026. Each record was verified 16 October 2026.

Hundreds of other rows have a number in the empty-spool field. Their provenance lists spool weight and does not name the empty-spool field. Those numbers are not used on this page.
