Intersect overlapping / aligned components for 3D Printing?

[giorgio1979]

Hello,

I have some overlapping or touching components that I wish to 3d print. Do I need to intersect ("intersect faces") them, or it does not matter at all when it comes to printing the design?

Normally, you will need a single solid volume, so you will need to intersect and delete the inner geometry.

Ouch, thanks Cotty. I guess it will be better to "explode" all of the components in that case in a final model file.
