Model size is the biggest driver
Scaling a model up increases volume quickly. A small scale change can have a large effect on filament use.

Infill, walls, and supports change usage
Higher infill, thicker walls, and support-heavy orientations all increase filament use. Preview the slicer estimate before printing.
Multi-color printing can add waste
Frequent material changes may add purge material and time. Plan color regions carefully when filament use matters.
Use inventory before printing
PrintNext helps compare planned usage against your available filament so you know whether a spool can finish the print.
FAQ
Common questions
How do I know how much filament a print uses?
Use slicer estimates, then compare the estimate with your remaining spool weight.
What setting affects filament use most?
Model scale is often the largest driver, followed by infill, walls, supports, and purge waste.
Do supports use a lot of filament?
They can, especially for large overhangs or inefficient orientations.
Can PrintNext help prevent running out?
PrintNext inventory workflows help compare estimated usage with the filament you have available.
