3D print filament estimate
Estimate filament mass and length from solid material volume. Use the sliced material volume rather than the outside volume of a hollow object.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
Measure materials and test a small sample before cutting, buying or building. Allow for real tolerances, waste and manufacturer instructions.

How it works
Mass = solid volume × density × (1 + allowance). Filament length = volume / circular cross-sectional area.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Material mass: 68.2 g
- Filament length: 22.8663 m
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
