eSUN empty spool weight
Use these sourced tare weights to estimate how much filament remains on a eSUN spool. Spool designs and production batches can change, so weighing your own empty spool is still the most precise method.
Black spool (1 kg filament)
230 g empty spool
Manufacturer source · Nominal filament: 1000 g
eSUN publishes this tare weight in its eBOX spool-weight reference table.
Transparent spool (0.5 kg filament)
203 g empty spool
Manufacturer source · Nominal filament: 500 g
eSUN publishes this tare weight in its eBOX spool-weight reference table.
Black spool (0.5 kg filament)
212 g empty spool
Manufacturer source · Nominal filament: 500 g
eSUN publishes this tare weight in its eBOX spool-weight reference table.
How to calculate filament remaining
Weigh the loaded spool, then subtract the empty-spool tare weight. For example, a loaded spool weighing 720 g with a 220 g empty spool has about 500 g of filament remaining.
Track every eSUN spool you own
Makeratory keeps each spool’s remaining weight, material, color, location, and cost together so you can see what is available before planning the next print.
