How to Use This Calculator
  1. Enter the model volume (cm³) from your slicer's statistics panel.
  2. Set infill percentage (%) and select the infill pattern (grid, gyroid, honeycomb, etc.).
  3. Enter wall thickness (number of perimeters × line width in mm).
  4. Review estimated part weight (g), material volume, strength score, and wall-to-infill ratio.

What each input means

Model Volume
Total outer volume of the model in cubic centimeters (from slicer or CAD).
Infill Percentage
Percentage of the interior filled with material. 20% is typical for prototypes, 50%+ for functional parts.
Infill Pattern
Infill geometry pattern. Gyroid offers best strength-to-weight ratio; honeycomb is material-efficient.
Wall Thickness
Total wall (perimeter) thickness. Typically 2-3 wall lines at 0.4mm nozzle = 0.8-1.2mm.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Model Volume = 100, Infill Percentage = 20, Infill Pattern = 1, Wall Thickness = 1.2 = 4 input(s) provided
  2. Calculate Estimated Weight
    Estimated Weight
    40.19 = 40.19
  3. Calculate Material Volume
    Material Volume
    32.41 = 32.41
  4. Calculate Strength Score
    Strength Score
    2 = 2
  5. Calculate Infill Volume
    Infill Volume
    16.9 = 16.9
