No. The estimate includes filament, machine allocation, electricity, labor, failed attempts, fulfillment, and optional payment fees. Taxes and unentered costs are not included.
Here, margin is the share of the selling price left after the costs and payment fees you enter. It is not net profit. Taxes, financing, customer acquisition, and missing overhead may reduce what you keep.
Yes. Import a text G-code file with a single Prusa-style gram-mass comment and supported print-time comments. Review the values before applying them. Binary G-code, length-only filament, and ambiguous multi-material metadata are not supported.
No. This app calculates and reads files in your browser. Saving is optional and uses this browser profile only. Normal page requests may still be logged by the static hosting provider.
The workflow is designed for single-material filament jobs. Washing, curing, resin-specific losses, and mixed-material allocations are not modeled. Do not treat an FDM estimate as a complete resin quote.
Check one cost first, then bring it into a complete job quote.
3D Print Filament Cost Calculator — Calculate the material cost of one 3D print from the spool price, net spool weight and slicer estimate.
3D Printer Electricity Cost Calculator — Estimate a printer’s energy cost from average power, print duration and your electricity price per kWh.

Real numbers behind the calculator: electricity price by state, filament type, printer model, and part type.
Electricity cost by state: 51 states compared, 2024 U.S. Energy Information Administration (EIA-861).
Filament types and material cost: 8 materials compared.
Printer models and running cost: 10 printers compared.
Job quotes by part type: 8 worked examples.
Cost to run a 3D printer per hour and 3D printing price per gram.
With 120 g at $24/kg, 6 hours at 120 W and $0.20/kWh, a $800 printer over 4,000 hours, $0.10/hour maintenance reserve, a 10% failure probability per attempt, 35 minutes of paid labor at $30/hour, and $10 of packaging, shipping, and overhead, the expected successful-job cost is $32.86. At a 40% gross margin, the reverse-solved quote is $32.86 ÷ (1 − 0.40) = $54.77. This is arithmetic from the starting inputs, not a market price.
After delivery, enter total grams, machine hours, and labor minutes in the final group. The receipt compares those totals with the expected successful-job cost so you can adjust the failure probability, labor estimate, or machine reserve on the next quote. A completed job is evidence about your shop, not a promise about another model or material.
Slicer comments can supply mass and time, but they do not prove measured power, labor, failure history, platform fees, taxes, or a profitable price. Replace the example with shop measurements and export the method version with the quote.
