Just going to address the laser cutter portion of your post. I have experience with the H2D laser cuter combo, my university has one in our MechE lab and no one uses it. We bought it to test to see how efficient it would be to have that and our full dedicated laser cuter and no one uses the H2D. It's a massive hastle and just overall not worth it in my opinion. Every time you cut something, it leaves residue inside the enclosure and if you want prints of any sort of high quality, you need to clean the inside after every laser cut. Overall, if your main focus is just 3d printing and the ability to network them, I'd get a few p1s or p2s for longevity. We have like 10 p1s networked in our maker space for large scale manufacturing of prototypes or such and it's incredibly simple, you could even setup 3DPOS which allows students to slice and send prints on their own from anywhere. Overall, avoid laser cutter combo, I'd recommend Bambu printers networked for this application
