Tips

1
PLA is ~1.24g/cm³, ABS ~1.04g/cm³. Material choice significantly affects weight and cost.
2
Wall thickness contributes more to strength than infill percentage in most cases.

Open formula

Weight = (Shell Volume + Infill Volume) × Density
Length = Weight / (π × (d/2)² × Density)
Cost = Weight / Spool Weight × Spool Cost

Calculates filament weight from shell and infill volumes, converts to length using filament diameter, and estimates cost per print.
