Inputs
What 3D Price calculates.
Average printer watts
Print hours and minutes
Electricity cost per kWh
Quantity and batch scaling
Machine wear per print hour
Total customer price
Use average wattage
The number on a power supply is not the same as average draw. A plug-in power meter gives the best value; otherwise use a conservative estimate and review it later.
Do not stop at power
Power cost alone is usually small. The full price should still include material, wear, failed prints, active labor, packaging, fees and margin.
