Frequently Asked Questions

low layer height, such as 0.01mm, there is very little room for the
plastic to exit the nozzle. This gap below the nozzle is only
0.01mm tall, which means that the plastic may have a difficult
time exiting the extruder. Double check to make sure you are
using a reasonable layer height for your printer. You can view this
setting by clicking “Edit Process Settings” and selecting the Layer
tab. If you are printing at a very small layer height, try increasing
the value to see if the problem goes away.
(4) Incorrect extrusion width
Another setting to check within Simplify3D is the extrusion
width that you have specified for your extruder. You can find this
setting by clicking “Edit Process Settings” and going to the
Extruder tab. Each extruder can have its own unique extrusion
width, so make sure you select the appropriate extruder from the
list of the left to view the settings for that specific extruder. If you
extrusion width is significantly smaller than your nozzle diameter,
this may cause extrusion issues. As a general rule of thumb, the
extrusion width should be within 100-150% of the nozzle diameter.
If your extrusion width is far below the nozzle diameter (for
example, a 0.2mm extrusion width for a 0.4mm nozzle), then your
extruder won’t be able to push a consistent flow of filament.
(5) Poor quality filament
One of the most common causes of inconsistent extrusion that
we have not mentioned yet is the quality of the filament that you
are printing with. Low-quality filament may contain extra
additives that impact the consistency of the plastic. Others may
have an inconsistent filament diameter, which will also cause
