Overextrusion

Your 3D printer extrudes more filament than necessary? You detect out leaning layers on the surface of your print? That is called over extrusion.

It happens when your software and printer are not configured – the software doesn´t give the right input for the right amount of extrusion of your FDM printer.

Filament diameter / extrusion multiplier

If you detect over extrusion at your print you can manage this issue by decreasing the extrusion multiplier (sometimes it is also called “flow rate”). Every printer and every extruder have its own specific and perfect settings.

Try to decrease the extrusion multiplier in your software in 5% steps. If the multiplier is set to 1, try 0,95 then 0,9, …

Below you will find screenshots showing where to change the settings on Simplify3D, Cura and Slic3r.
