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

This catalog attributes an empty-spool weight to a manufacturer page on four ELEGOO rows: 154 ± 10 g on PETG HF, PETG Glitter, and ASA-CF, and 165 ± 5 g on TPU 72D. Weigh the loose filament, or weigh the spool and subtract an empty-spool weight only when that maker publishes one for that spool.

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](/answers/filament_runout) is the printer stopping. [Dimensional accuracy](/answers/dimensional) 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](/brand/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](/brand/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](/brand/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](/brand/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.
