0.036 is the example result. Read it using the units and relationship stated below.
3D Print Electricity Cost uses printer power (w), print time (hours), electricity rate per kwh.
Making a print estimate reflect the work behind the part
For 3d print electricity cost, the relationship is Result = ([Printer power (W)] ÷ 1000) × [Print time (hours)] × [Electricity rate per kWh]. The amount depends on the supplied printer power (w), print time (hours), rather than a live market price or a value imported from another record. Filament cost is only one component of a printed part. Machine time, failed jobs, setup, labour and fulfilment can materially change contribution. Compare grams with the usable spool weight, rather than the label price alone.
What the model includes
Result = ([Printer power (W)] ÷ 1000) × [Print time (hours)] × [Electricity rate per kWh] Use measured print duration where possible and keep machine-hour charges separate from electricity. If the machine rate already includes energy or labour, entering those amounts again double counts them. The model cannot infer a failure rate from a successful test print. A quote still needs the part requirements and production method. Material choice, orientation and finishing affect quality; this estimate does not establish mechanical suitability or guarantee the print will succeed.
Example with the supplied inputs
Printer power (W): 120; Print time (hours): 2; Electricity rate per kWh: 0.15. Result: 0.036. The values are illustrative.
Compare one changed input
Printer power (W) changes from 120 to 132. The result becomes 0.0396. All other inputs remain fixed.
Calculation rule
Result = ([Printer power (W)] ÷ 1000) × [Print time (hours)] × [Electricity rate per kWh]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Printer power (W) | 120 | Use the source quantity represented by printer power (w). Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Print time (hours) | 2 | Use the duration unit stated in print time (hours). A time period is not interchangeable with a currency amount or a count of events. |
| Electricity rate per kWh | 0.15 | Measure electricity rate per kwh in the displayed unit. Convert the source measurement before entry if it uses another system; a changed label does not perform a unit conversion. |
Output: 0.036 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Printer power (W), Print time (hours), Electricity rate per kWh. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Printer power (W) on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 0.036.
Change Printer power (W) from 120 to 132 while keeping every other value fixed. The result becomes 0.0396. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
