Nesting capabilities of slicer (overview) (lemmy.ml)

Short overview of how good the nesting capabilities of various 3D slicer are.

The task is simple: placing as many of these shapes on a 200x300mm printed as possible. Manual (quick and dirty for reference): 6 pcs.

Ranking:

Ultimaker Cura: 7 pcs.
human (me): 6 pcs.
Orca slicer: 5 pcs.
PrusaSlicer & BCN3D stratos: 4 pcs. By switching (for this particular part) from the worst (Prusa) to the best (Cura) slicer the nesting performance improved by a whopping 75%!

BCN3D Stratos (forked from an old version of Cura):

Did you turn on Automatic Rotations in Prusaslicer? By default it's left off and just tiles your part when you duplicate it.

Default settings. Where is the option to rotate it?

Providing it manually with 90° rotated and using the auto arrange instead of fill bed: 5 pcs. Still not a great result.

Right click on the auto- arrange icon. I think the checkbox is in there.

Yeah, it's still not great.

Thanks. See the other comment for details how now performs.

There's also a setting for minimum spacing between parts. The default is overly cautious iirc, I'd suggest lowering it and trying again, though I don't expect it to change much

Improved but still not a match to Ultimaker Cura.

Prusa is very slow compared to Cura as PrusaSlicer needs every option checked including Geometry handling accurate to sometimes get 7 pcs. matching Cura performance. If the result is 7 or 6 pcs. depends on where the part originally was placed on the print bed (or luck? run to run variance?). Not a reliable software for nesting.

With fast and balanced setting it only does 6 pcs.
