How to slice/cut, mirror, boolean, and separate shells in Netfabb and Simplify3D
Autodesk Netfabb is the slicing/cutting software we recommend. 30 day FREE trial is available at https://www.autodesk.com/products/netfabb/free-trial. If you are a student, the software is completely free at https://www.autodesk.com/education/free-software/netfabb-premium.
How to slice 3D printable model in Netfabb.
This video will show you how to separate shells or fuse shells (watertight/manifold). Our latest project files do not separate as many pieces as it used to as it is not necessary. However, we plan on going back and separate details by its different colors so that we can paint them separately without masking parts.

In Netfabb, I slice using plane cut, mirror via reflect tools, and use Boolean (union/subtract/intersect) in the Premium version to combine or subtract meshes. Then use “Separate Shells” to break composite models into discrete parts. In Simplify3D, I import separate shells as individual STL parts (avoid doing complex Boolean in the slicer).
