Filament cost calculator FAQ
Do I use the weight of the whole spool?
No. Use net filament weight, excluding the plastic spool and packaging. A 500 g spool is not the same as a 1,000 g spool.
Are supports and purge included?
Use your slicer’s total material use. If supports and purge are already counted, do not add them a second time.
Is this the full cost of a print?
No. This page calculates material only. Electricity, machine time, labor and extras belong in the full print-cost calculator.
