3D Printing Budget Calculator Examples
Worked examples showing how material, electricity and machine overhead affect a 3D printing budget.
These examples show how the calculator handles a simple prototype, a long functional print and a support-heavy job. Each uses estimated direct costs only, so separate work such as design and finishing is not included.

How to Read Your Results
Material cost uses the filament amount after the waste and failure allowance is added.
Electricity cost is usually based on average power draw, not the maximum wattage stated on the printer label.
Machine-use cost is optional; entering zero excludes printer overhead from the result.
The total is an estimated direct cost for one completed print, not automatically a retail price.
Use the cost breakdown to identify whether material, runtime or printer overhead is the largest budget driver.
Assumptions & Important Notes
- All filament prices are expressed per kilogram.
- Print-time estimates are assumed to be reasonably close to actual machine runtime.
- Power draw is treated as an average over the print, including typical heating and printing activity.
- No design time, operator labour, post-processing, packaging, delivery or taxes are included.

Frequently Asked Questions
Can I use a zero machine-use rate in the examples?
Yes. A rate of zero leaves machine overhead out of the total and shows material plus electricity only.
Why does the long print have a low electricity cost?
Even long prints may use only a few kilowatt-hours when average power draw is measured in hundreds of watts. Your local electricity rate and heating setup can change the result.
When should I use a higher waste percentage?
A higher percentage may be useful for supported models, multi-colour purging, test pieces, difficult materials or jobs with a greater chance of retrying.
Do these examples include labour?
No. They use an optional machine-use allowance only. Setup, monitoring, finishing and other labour can be calculated separately.
