Any Ideas for how to Nest Parts in 3D for SLS, SLA etc.?

Is there any CAM software for nesting 3D models for 3D printing using SLS, SLA etc. not CNC glue guns?

github.com/Jack000/SVGnest Saw this for 2D nesting. Might be handy to some here.

www.autodesk.com/compare/compare-features/netfabb not free or open, and I don't know how well it actually works for 3D packing.

I do have experience with FDM printing. Most of this is handled in the slicer program. I assume you have similar software for your printer. As for modeling, FreeCAD can handle that quite well. Without launching into a multipart tutorial, I’ll say this. While designing in the, “Part Design Workbench”, don’t select the create body icon as suggested by the prompt. Instead select the yellow part Icon located on tool bar above. It looks just like the body icon except for the color. Once part is selected, then click on the part icon in your model tree. Then select the body icon from the toolbar. After that, you create a sketch within the body. As an added bonus, inside the part tree, all of your modeling enjoys its own private coordinate system which allows you to move your part anywhere in the global coordinate system by clicking on the part icon in your tree and adjusting the position in the lower combo box menu. After you create the first part, create the second etc. Once you have all of your parts positioned in the global coordinate system, create a mesh of all of the parts. From the mesh tool box, combine all meshes in to one mesh, they should still be separated in space. Select the combined mesh and export it to an STL file. I think that should work unless your printer software cannot handle an STL file.

The printers are all custom SLS, SLA, LCD/DLP etc and run LinuxCNC. Models come from customers from all over and may be in any popular format IGES, STEP, STL, or native SW, NX etc.
