Frequently Asked Questions

achieve the same effect. If you are noticing gaps between the
extrusions in your top surface, the first thing you should try is
increasing the number of top solid layers. For example, if you
noticed the problem using only 3 top solid layers, try printing with
5 top solid layers to see if the problem is improved. Note that
additional solid layers will occur within your part dimension and
do not add size to the exterior of your part. You can adjust the
solid layer settings by clicking “Edit Process Settings” and
selecting the Layer tab.
(2) Infill percentage is too low
The infill on the inside of your part will act as the foundation
for the layers above it. The solid layers at the top of your part will
need to print on top of this foundation. If your infill percentage is
very low, there will be large air gaps in your infill. For example, if
you are using an infill percentage of only 10%, the remaining 90%
of the interior of your part would be hollow, and this would create
some very large air gaps that the solid layers would need to print
on top of. If you have tried increasing the number of top solid
layers and you are still seeings gaps in the top of your print, you
may want to try increasing your infill percentage to see if the gaps
go away. For example, if your infill percentage was previously
30%, try using a 50% infill percentage, as this would provide a
much better foundation for the solid layers at the top of your print.
(3) Under-Extrusion
If you have tried increasing the infill percentage and the
number of top solid layers, yet you are still seeing gaps in the tops
of your print, then you likely have an under-extrusion issue. This
