Slic3r
4. Filament Diameter
For Slic3r to produce accurate results it must know as accurately as possible
how much material is pushed through the extruder. Therefore it is vital to
give it as precise a value as possible for the filament diameter.
Although the filament used in FFF printers is sold as being either
3mm or 1.75mm this is only a general guide. The diameter can vary
between manufacturers and even between batches. Therefore it is highly
recommended to take multiple measurements from along a length of the
filament and use the average. For example, measurements of 2.89, 2.88,
2.90 and 2.91 would yield an average of 2.895, and so this would be used.
