Worked Examples
3D Printing Cost and Calibration Examples
Use these example calculations to understand the inputs, outputs, formulas, and assumptions behind the calculators.
How these examples connect to calculators
Each example shows concrete inputs, outputs, and formulas, then links back to the matching calculator so you can replace the sample numbers with your own slicer data or calibration measurements.
Start with an example when you want to check the math before using your own assumptions. Start with a calculator when you already have the slicer weight, print time, spool price, resin volume, or extrusion measurement ready.
Cost, quote, and filament examples
Use the cost examples for material, electricity, labor, and markup decisions. Use filament examples when you need cost per gram, cost per meter, or material comparison context.
- Price a 100 g PLA print before creating a customer quote.
- Calculate filament cost per gram before filling a material line.
- Compare FDM and resin material cost before choosing a print process.
- Compare PLA and PETG material cost before quoting a material upgrade.
Calibration and flow examples
Use the calibration examples to understand how extrusion measurements connect to E-steps, Klipper rotation distance, and volumetric flow calculators.
- Check Klipper rotation_distance math from a 100 mm extrusion test.
- Check Marlin E-steps math before sending M92 and M500.
- Check 0.4 mm nozzle volumetric flow before raising speed or layer height.
When to Use an Example Instead of a Calculator
Use an example when you are learning the formula, checking a quote conversation, or explaining a result to someone else. Use the calculator when you want a live browser-local result from your own manually entered numbers.
The examples do not fetch material prices, upload model files, connect to firmware, or save quote history. They are fixed worked calculations that point to the active tool for your real print, spool, resin bottle, or calibration test.
