How to Use Model Weight Calculator

  1. Enter total model cubic volume (cm³ or mm³).
  2. Select material density (PLA 1.24, PETG 1.27, ABS 1.04, TPU 1.21, Resin 1.12 g/cm³).
  3. Enter target infill percentage (e.g. 15% gyroid or grid infill).
  4. View estimated print weight in grams and cost per unit.

What is the Model Weight Calculator?

Converts geometric 3D volume into physical weight in grams across various thermoplastic and photopolymer densities.

Formula Used

• Solid Mass (g) = Volume (cm³) × Density (g/cm³) • Infilled Mass (g) ≈ Volume (cm³) × Density × (0.25 + 0.75 × (Infill % / 100))

Real-World Example

A 80 cm³ robotic enclosure printed in PETG (1.27 g/cm³) with 20% infill weighs approximately: 80 × 1.27 × (0.25 + 0.75 × 0.20) = 40.6 grams.

Accuracy and Limitations

Wall perimeter count and top/bottom solid layers contribute a baseline solid volume before infill calculation.

Who It Is For

Drone builders minimizing payload weight and inventory managers forecasting material needs.

Frequently Asked Questions

How do you calculate 3D print weight from volume?
Weight (grams) = Volume (cm³) × Density (g/cm³). For infill models: Effective Weight = (Shell Volume + Infill Volume × Infill %) × Density.
