How to Calculate Filament Usage
This calculator uses the formula: Length = Weight / (Density × π × (Diameter/2)²)
Your slicer software (Cura, PrusaSlicer, etc.) will tell you the estimated filament weight or length for a print. Use this calculator to:
- Check if you have enough filament on your spool
- Calculate the material cost of a print
- Convert between weight and length when your slicer shows one but not the other
