Infill Volume Calculator
Estimate infill volume and weight.
Enter total model volume, infill percentage, and material density to get infill volume and weight.
Defaults use common densities; adjust for your material.
Shell factor approximates walls/top/bottom; infill applies to the remaining volume.
Examples
- 150 cm³, 15% infill, shell 0.35, PLA → printed ~130 cm³, ~161 g.
- 300 cm³, 20% infill, shell 0.35, PETG → printed ~263 cm³, ~334 g.
FAQ
What about supports?
Not included. Add buffer in cost calculators if supports are heavy.
Shell factor?
Rough share of walls/top/bottom. Typical is ~0.3–0.4 for 3 walls; adjust for thicker walls.
