How to Measure Filament Left on a Spool

“Do you have enough filament?”  Fabbaloo asked yesterday.  When a 3D job loads for the weekend, there is always the concern that it might run out in the middle of a print.  Plural Additive Manufacturing came up with a helpful tool: a quick, rough estimation spreadsheet.  The Excel spreadsheet includes a list of materials, the material densities, average empty spool weight, and cost per cubic centimeter (cc) if desired.

Note: average empty spool weight is one source of variation. It’s not perfect, but this spreadsheet lets you know when the spool is getting close to empty.
