How it works

The infill percentage multiplies model volume to estimate plastic volume, which is multiplied by material density for mass. A separate full-solid result provides comparison.

  • Twenty percent is a visual starting point, not a strength guarantee.
  • Density remains selectable for different filaments.

Worked example

A 40cm3 part at 20% infill
Input
											Model volume cm3: 40
Infill percent: 20
Output
												Material volume cm3: 8
Weight g: 9.92
Weight at100 percent g: 49.6
Weight saved g: 39.68

When to use this

Slicer profiles, functional bracket planning, and hollow-versus-solid cost checks estimate infill.

Edge cases

  • Infill percentage is not a direct strength percentage.
  • Zero infill ignores walls and shells in this simplified model.
  • Changing material changes grams without changing volume.
