Wow. The value of the sapphire was mentioned elsewhere here and it is certainly true. I may have a "fat grant" coming in and if I do we probably will want on on-site printer for the staff mechanical engineer. Depending on what negotiations I do I would consider a high end 50micron printer but if not I think the sapphire makes sense. Makes me want to replace my personal Creality!!

I have never done Pet-G or PA6.. Does the ender handle it?

Laser cutters are nice--I use a band saw etc here in my shop--one of my contracts has a great water jet cutter but $$ and time get in the way

Tell us what slicer you are using!

cheers!
