eSUN empty spool weight (tare)

An empty eSUN spool weighs about 220 g — that is the tare to subtract from your scale reading before trusting it. At 0.335 meters per gram of 1.75 mm PLA, ignoring it overestimates your remaining filament by ~74 meters. The spool remaining calculator applies this exact preset for you, and the full brand-by-brand table lives in the empty spool weight database.

How to use this number

  1. Weigh the spool on a kitchen scale with 1 g resolution (not a bathroom scale — they are inaccurate below a few kilograms).
  2. Subtract the tare — scale reading minus 220 g gives the remaining filament in grams.
  3. Convert to meters — multiply grams by 0.335 for 1.75 mm PLA, or use the filament length to weight calculator for other materials.
  4. Skip the math — the spool remaining calculator does all three steps with the eSUN preset and shows grams, meters and percent left.

About this value

eSUN ships on a standard plastic spool in the middle of the weight range. These are community-measured approximations for standard 1 kg spools (compiled by spool trackers such as filamiq and sigmafilament). Manufacturers revise spool designs without notice, so real weights drift by tens of grams between batches — weigh your own spool if the exact number matters.

Frequently asked questions

How much does an empty eSUN spool weigh?
About 220 g for the standard 1 kg plastic spool. It is a community-measured approximation — batches and spool revisions vary by tens of grams, so weigh your own empty spool if the exact number matters.

How do I calculate how much eSUN filament is left?
Weigh the spool on a kitchen scale, subtract the 220 g tare, and you have the remaining grams. Multiply by 0.335 for meters of 1.75 mm PLA — or let the spool remaining calculator do it with the eSUN preset built in.

Is the eSUN spool tare exact?
No. These are community-measured approximations and manufacturers change spool designs without notice — weights can drift by tens of grams between batches and revisions. For an exact figure, weigh an empty spool of the same brand and revision yourself.

What happens if I forget to subtract the eSUN spool weight?
Your scale overestimates the remaining filament by the full tare: 220 g looks like ~74 meters of 1.75 mm PLA you do not have — easily the difference between a finished print and an overnight failure.
