Formula and methodology
Formula: Material volume=model volume×infill/100×(1+support/100)×(1+waste/100); mass=volume×density; filament length=volume×1000/(πd²/4); deposition time=volume×1000/flow.
The calculator turns a supplied model volume into a transparent planning estimate. Infill, supports, and waste are visible multipliers; density, filament diameter, and effective volumetric flow remain user inputs because slicer settings and machine behavior differ.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Model volume — cm³; minimum 1.0E-6; maximum 1000000000
- Infill percentage — %; minimum 1.0E-6; maximum 100
- Support allowance — %; minimum 0; maximum 1000
- Waste allowance — %; minimum 0; maximum 1000
- Filament density — g/cm³; minimum 1.0E-6; maximum 100
- Filament diameter — mm; minimum 1.0E-6; maximum 100
- Effective print flow — mm³/s; minimum 1.0E-6; maximum 1000000000
- Spool mass — kg; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Model volume | 100 |
| Infill percentage | 20 |
| Support allowance | 10 |
| Waste allowance | 5 |
| Filament density | 1.24 |
| Filament diameter | 1.75 |
| Effective print flow | 12 |
| Spool mass | 1 |
Estimated material is 26.25 cm³, about 32.55 g, about 10.92 m of filament, and 36.46 minutes of deposition; one 1 kg spool is enough in this model.
Assumptions and limits
- Model volume is a geometric solid volume and the infill percentage represents the material fraction used by this simplified model.
- Support and waste allowances are user-entered planning multipliers, not universal slicer defaults.
- The filament is treated as a uniform cylinder with the entered diameter and density.
- Layer height, walls, top and bottom skins, retraction, purge towers, machine acceleration, pauses, and slicer-specific toolpaths are not modeled.
