How to work out the cost of a 3D print
The cost of a print is filament, power and machine time. Here is an example for 120 g of filament and 4.5 hours of printing, with Gantry’s default settings.
- Filament: 120 g at 80 PLN per kilogram comes to 9.60 PLN.
- Power: 150 W for 4.5 hours is 0.675 kWh, or 0.68 PLN at 1 PLN per kWh.
- Machine time: 0 PLN in the default settings.
- In total the print costs 10.28 PLN.
The plug reads power about every 5 seconds
With a Tasmota or Shelly plug, Gantry reads power throughout the print. Each result is labelled: measured, partly measured or estimated.
Pricing covers the full cost of a job
To the customer price you can add markup, income tax, VAT, platform commission, a reserve for failed prints, packaging and your own work. This is an estimate for pricing, not tax advice.

Frequently asked questions
Do I need a plug that measures power?
No. Without one, Gantry estimates energy from the printer’s average power. A Tasmota or Shelly plug gives you measurements during the print.
How do I know if a result is measured or estimated?
Each result is labelled: measured, partly measured or estimated.
