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. See the Plural support site for the spreadsheet or Google Play store to download the app.
