Frequently Asked Questions

see bridging extrusions and verify that these lines are shown in
yellow. If the bridging area is not shown in yellow, there are a two
settings you will want to check. Exit the preview, click “Edit
Process Settings”, and go to the Other tab to view your Bridging
settings. The first option in this section is the “Unsupported area
threshold”. This allows the software to ignore very small bridging
areas and focus on the larger bridging regions that may need
special settings. If you think your bridging area is not being
included, make sure that the area of your bridging region is larger
than this threshold value. The second setting to check is towards
the bottom of this list. By default, Simplify3D uses special
perimeter settings for any perimeters that are printed as part of a
bridging region, but you can also choose to use bridging settings
for these regions if you wish. To do this, enable the “Apply
bridging settings to perimeters” option, save your settings, and
then return to the Simplify3D preview to verify your changes.
(2) Check the angle used for the bridging infill
Simplify3D will automatically calculate the best infill
direction to use for your bridging regions. For example, if you are
bridging between two pillars aligned on the X-axis, the software
will automatically change the infill direction for that area to ensure
the infill is also being extruded along the X-axis. This greatly
improves your odds of success, so if you notice that you are
getting poor bridging results, you want to double-check to make
sure the infill is oriented in the correct direction. If you have
already verified that your bridging region is properly identified as
a yellow bridging region in Simplify3D, then this change should
