Chain Mail Slicing Challenge
Posted: Wed Feb 11, 2015 3:00 am
It seems that changes introduced in Slic3r since last year now prevent it from slicing the OpenSCAD model that produced the chain mail sheets described in my show-n-tell post:

For whatever reason, Slic3r now mostly uses the infill pattern on the bottom layer of the bridges, so the threads don't run directly across the gap. Unfortunately, the failure isn't consistent, with a few bridges having the proper bridge pattern and most other with infill, which means I can't just reorient the links to make the bridges come out right.
This picture is larger than I'd like, but it certainly shows the problem:
Three of the four bridges use infill and only one has proper bridging.
The first layer of these armor caps didn't work, either:
So I ran the STL files through Cura and KISSlicer, only to find neither created good bridges. I admit to not using those slicers, so perhaps it's a configuration issue, but they have fewer knobs than Slic3r and I didn't see anything obviously wrong.
As far as Slic3r is concerned, the STL files are manifold and have no problems. Meshlab shows a few self-intersecting faces on the peaks of the armor buttons, but a discussion on the OpenSCAD forum says that's an artifact of how Meshlab assigns vertices (or something like that).
After all that, I'd appreciate it if you folks would run the STL files through your slicer of choice and let me know what comes out.
The Slic3r bug report (Issue 2646) has a more detailed description & pix of the problems:

The attached ZIP file has the OpenSCAD source and the failing STL files.
Thanks kindly...
