Filament
Infill Material Estimator
Estimate internal material volume and mass from a model envelope, shell allowance, infill percentage, and material density.
How the calculation works
Infill material = (model envelope − shell volume) × infill percentage × density.
How to use this result
Use it for early design comparison when a slicer estimate is not available. It is deliberately an approximation: real infill geometry, top layers, supports, and voids change the final mass.
