Cost of a print

Use the part weight and print time estimated by the slicer.

Spool price

Net filament weight on the spool (g)

Part weight (g)

Print time (hours)

Average printer consumption (W)

The rated power in technical specifications is a maximum, not the average consumption. For an accurate value, measure with a plug-in energy meter.

Metres of filament from weight

To find out how much filament is left on a spool: weigh it and subtract the weight of the empty spool.

Filament weight (g)

Filament diameter (mm)

Density (g/cm³)

Density varies from material to material and is stated in the filament's technical data sheet.

Length

—

Formula: length = weight ÷ (density × π × (diameter ÷ 2)²).
