Filament Weight Calculator — Estimate Print Weight
Estimate how much filament a print will use based on model volume, infill and material.
How We Calculate This
Calculation Method
The calculator estimates print weight by considering both the solid shell and sparse infill:
- Solid weight = Model volume x Material density
- Shell weight = Solid weight x Shell fraction (approx 15%)
- Infill weight = Solid weight x (1 - Shell fraction) x (Infill % / 100)
- Total weight = Shell weight + Infill weight
The shell fraction accounts for perimeters, top and bottom layers which are printed solid regardless of infill setting.
