3D Printing Material Cost Calculator Guide
Enter the model's print volume (cm³), infill percentage, material type, and filament price per kg. The calculator shows material usage in grams and estimated cost, including a +20% estimate to account for shells, supports, and seam material.
How to Find Your Model's Volume
Open your STL in a slicer like Cura or PrusaSlicer to see the model volume in cm³. You can also find it in your CAD software under model properties. The volume shown is the solid bounding volume — actual usage depends on infill settings.
Infill Guide
- 10–20% — decorative prints, prototypes
- 20–40% — standard functional parts
- 50–80% — mechanical parts needing strength
- 100% — maximum strength, solid prints
Frequently Asked Questions
Usage = 50 × 0.2 × 1.24 = 12.4 g. Cost = 12.4/1000 × $25 = $0.31. With 20% overhead for shells: ~$0.37.
Resin is generally more expensive per kg and requires post-processing (UV curing, washing). It offers much finer detail resolution but adds time and safety considerations.
