How to Read Your Results
Estimated material required includes the selected waste allowance and is useful for material planning.
Net print weight excludes waste and helps show the estimated mass of the model plus supports.
Raw material cost is not a full manufacturing cost or customer quote.
Compare the estimate with slicer output and completed-job records to improve future inputs.
Review support volume and waste allowance carefully for complex, multi-part or production jobs.
Assumptions & Important Notes
- All volumes are measured in cm³ before density conversion.
- Shell and support density percentages are planning estimates.
- Each example uses an illustrative material price and should not be treated as a market rate.
- The calculation excludes operating and post-processing costs.

Frequently Asked Questions
Can these examples be used for filament and resin prints?
Yes, provided the relevant density, model assumptions, support estimate and material price are entered for the process.
Why can a low-infill part still weigh more than expected?
Solid shells, top and bottom layers, supports and waste can make up a significant share of total material.
How should I estimate support volume before slicing?
Use slicer data when available. Before slicing, use an informed estimate based on similar orientations and prior jobs.
Is raw material cost the same as the price of a print?
No. A print price may also reflect machine time, labour, setup, finishing, overhead and margin.
