3D Print Infill Calculator

See how infill percentage affects weight, filament cost, and print time. Compare any infill level against solid (100%) side by side.

Inputs

Solid print weight (g) at 100% infill

Check your slicer at 100% infill, or use filament remaining calculator

Price per gram ($)

Print time at 100% infill (hours, optional)

Infill pattern

5-15%Strength: Low

Decorative items, vases, display models

Fine for anything not load-bearing. Saves significant filament.

15-25%Strength: Medium

Everyday prints, toys, organizers, phone stands

The sweet spot for most hobby and Etsy prints. Good strength-to-filament ratio.

25-40%Strength: Good

Functional parts, brackets, enclosures

Noticeably heavier but much stronger. Use for parts that take load.

40-75%Strength: High

High-stress parts, tools, jigs

Diminishing returns above 40% for most patterns. Use gyroid or cubic for best strength per gram.

75-100%Strength: Maximum

Solid parts, press-fit components

Only necessary for extreme loads or thermal/pressure requirements.
