3D Printing Volume (Commercial) Calculator Examples
Worked examples showing how part dimensions, quantity, infill, waste and material type affect estimated 3D printing material use.
These examples use the calculator's bounding-envelope method. They are intended for early material planning; compare the result with a slicer estimate before preparing a production quote.

How to Read Your Results
Bounding volume is the rectangular envelope, not the exact amount of material in the CAD model.
Estimated material volume includes the selected support and waste allowance.
Estimated weight is useful for feedstock planning and handling estimates.
Estimated material cost covers feedstock only and is not a complete manufacturing price.
Use the same units consistently: dimensions in centimetres and density in g/cm³.
Assumptions & Important Notes
- All parts in a scenario are identical.
- Material consumption is estimated from dimensions and percentages rather than a generated toolpath.
- Prices are example values only and may not reflect current supplier pricing.

Frequently Asked Questions
Can I use these examples for resin printing?
Yes, if you enter the appropriate density, price and waste allowance, but resin supports and post-processing can affect actual consumption.
Why are the example material estimates larger than some slicer estimates?
The calculator begins with a rectangular envelope, whereas a slicer uses the actual model geometry and toolpath.
Should I use the same waste allowance for every job?
No. Adjust it for the process, orientation, support requirements, purge needs and expected failure risk.
Do these examples include labor or printer time?
No. They calculate raw material volume, weight and cost only.
