Infill Calculator

Calculate infill percentage needed for target strength, or find material usage at different infill densities.

Width (mm)

Depth (mm)

Height (mm)

Shell Thickness (mm)

How It Works

Enter your model dimensions and shell thickness. The calculator shows filament usage and estimated strength for common infill percentages from 10% to 100%.

Formula

Material Used = Base Volume x Infill% + Shell Volume

Frequently Asked Questions

What infill do I need for strong parts?

For functional parts, 40-60% infill provides good strength. For structural or load-bearing parts, use 80-100%. Decorative prints work fine at 10-20%.

What infill pattern is strongest?

Gyroid and cubic patterns are strongest for isotropic strength. Grid and lines are common and fast. Honeycomb is good for lateral strength.
