3D Printing Weight (Commercial) Calculator
Estimate the material weight and raw material cost of a commercial 3D print using part volume, infill, supports, density and waste allowance.
Overview
This commercial 3D printing weight calculator estimates the material needed for a print job from the model volume, shell and infill settings, support volume, material density and expected waste. It also converts the estimated consumption into a raw material cost using your price per kilogram.
How it works
The calculator estimates the material-filled portion of the model by combining the solid shell share with the infilled interior. It estimates support material separately, then adds both volumes and multiplies the result by material density to calculate weight. Finally, it applies the waste allowance and multiplies kilograms used by the entered material price. Because slicer paths and machine processes vary, this is best used as a planning or preliminary quoting estimate.
How to use this calculator
- 1Enter the model volume reported by your CAD software or slicer.
- 2Set the infill density and estimate the portion of the model made up of solid shells.
- 3Add support, raft and brim volume if the job uses them.
- 4Enter the density and purchase price of the printing material.
- 5Include a realistic waste allowance and review the estimated material weight and cost.

Frequently asked questions
How do I find a 3D model's volume?
Most CAD programs and slicers can report a model volume. Use the volume in cm³ before infill, shells and support settings are applied.
Why does infill not equal the final print weight percentage?
Walls, top layers and bottom layers are often solid, so they use more material than the infill percentage alone suggests. The solid shell volume input accounts for this.
Should supports be included in a commercial print estimate?
Yes. Supports, rafts, brims and purge material can be significant, especially for complex parts. Add their estimated volume and density where applicable.
What material density should I use?
Use the value from the supplier's technical data sheet when possible. Typical densities differ by material, formulation and moisture content.
Does the estimated cost include print time and labour?
No. The cost output covers raw material only. Add machine time, energy, labour, maintenance, finishing, packaging and overhead separately for a full production cost.
How much waste allowance should I use?
Choose an allowance based on your process history. It may include purging, setup material, failed parts, trimming and normal handling losses.

Assumptions and warnings
Assumptions
- The model and support volumes are measured in cubic centimetres.
- The solid shell percentage is an estimate of the model volume occupied by walls and solid top and bottom layers.
- Material density is consistent throughout the print.
- The waste allowance covers expected process losses but may not match every machine or workflow.
- The cost result includes raw material only, not machine time, labour, energy, finishing, shipping or overheads.
Warnings
- This calculator provides an operational estimate only; confirm material use with your slicer, machine records and production process before quoting a job.
- Actual consumption can vary due to purge cycles, support settings, failed prints, post-processing and material handling losses.
