A mechanical fillet is basically just some smoothing along a join between two objects. It can significantly reduce stress concentration, which is a big problem in 3D printed parts.
There's been some discussion on this in the past. The general consensus is "CGAL/openCSG doesn't support it, so we can't really do anything with it". But I figure it's not going to hurt to collect all the information in one place.
Still, it's a feature that a lot of people would appreciate. Sure, you can do it with very complicated multi-stage toroid stuff, but it requires a lot of work for what's a pretty simple operation in many cad apps.
Here's and old mailing list post where I brought it up, and the discussion about it.
Here someone has discussed fillet-ing algorithms.
