Empty Spool Weight Database 2022

Here’s a nifty trick: if you know the weight of your spool when it is empty, you can use that to track how far through a spool of filament you are during a print.

All you have to do is put the spool onto a spool holder, then put that onto a kitchen scale while it’s printing and watch as its weight falls.

When it gets close to the weight of your spool, you will know if there is enough filament left to complete the print. If not, then you can get ready to swap in a new spool.

How to find the empty spool weights of a full spool

Suppose you don’t see the spool you are looking for in the above database. How do you find the empty spool weight without removing all of the filament from a spool?

You might not be able to get the exact empty weight of a spool, but you should be able to calculate a close enough estimation.

Here’s how to estimate the empty weight of a full spool:

  1. Cut off a 1 cm length of filament, say a centimeter or less, and weigh it.
  2. Note that the approximate length of the filament on your spool is 330 meters for 1.75 mm diameter filament on a 1kg spool, and 110 meters for a 3.00 mm diameter filament on a 1kg spool. If you can find a more exact length from the manufacturer, even better.
  3. Multiply the weight of your 1 cm sample section of the filament by the full length of filament on the spool (approx. 3300 cm). Don’t forget to subtract the weight of the 1 cm sample.
  4. Finally, weigh the spool and subtract the total filament weight from the total spool weight and you will have a usable approximation of the weight of your empty spool.

    ZYLTech spools for 1kg spools are approximately 187g. Black. I haven’t measured the dimensions but this info came from an email exchange I had with their customer service regarding the issue who went into the warehouse and weighed several spools and gave me an average.
