Infill Calculator
Calculate optimal infill percentage for your 3D print.
Balance strength, weight, material usage, and print time.
Infill Analysis
Infill is the internal structure of a 3D print. It determines the strength, weight, and material usage.
Common infill percentages:
- 0–5%: Hollow/nearly hollow — decorative items only
- 10–15%: Light use — display models, prototypes
- 20–25%: Standard — good balance of strength and speed
- 40–50%: Strong — functional parts, moderate stress
- 60–80%: Very strong — load-bearing, mechanical parts
- 100%: Solid — maximum strength, most material and time
Infill patterns and their strengths:
- Grid: Good all-around, fast to print
- Gyroid: Excellent strength in all directions, smooth stress distribution
- Triangles: Very strong laterally, good for structural parts
- Lightning: Minimal material, only supports top surfaces
Material savings estimate: Approximate total filament usage = (Infill% × Volume × 0.8) + (Shell Volume). More walls/perimeters can replace higher infill for many use cases.
