Spool Life Calculator — How Long Will a Spool Last?
Estimate how many prints and how many weeks you can get from one spool of filament.
How We Calculate This
Formula
- Usable weight = Spool weight x (1 - Waste %)
- Total prints = Usable weight / Average print weight
- Duration = Total prints / Prints per week
