Frequently Asked Questions

under-extrusion issues, then you need to adjust your extrusion
multiplier. This is a very useful setting in Cura that allows you to
easily modify the amount of filament that is extruded (otherwise
known as the flow rate). You can find this setting by clicking “Edit
Process Settings” and going to the Extruder tab. Each extruder on
your printer can have a unique extrusion multiplier, so if you are
trying to modify the flow rate for a specific extruder, make sure to
select it from the list on the left to load the settings for that
extruder. As an example, if your extrusion multiplier was 1.0
previously and you change it to 1.05, it means you will be
extruding 5% more plastic than you were previously. It is typical
for PLA to print with an extrusion multiplier near 0.9, while ABS
tends to have extrusion multipliers closer to 1.0. Try increasing
your extrusion multiplier by 5%, and then reprint the test cube to
see if you still have gaps between your perimeters.
4: Over-Extrusion
The software is constantly working together with your printer
to make sure that your nozzle is extruding the correct amount of
plastic. This precise extrusion is an important factor in achieving
good print quality. However, most 3D printers have no way of
