when my daughter went to school, they had several computer labs, with one computer per student for that lesson,
nowadays its nearer to a computer per pupil (or maybe a tablet) everything is done interactively - even down to homework being sent to the students tablet.
my point with the above being - you have to start somewhere.
even with a single printer you can teach, the next step would be a 3d printing lab, with a number of machines, then you teach the students how to design and build their own printers (or make them up from kits) then the next generation treat the technology as something they just know about instinctively and use.
half the time you will be teaching the design aspects, the printer will just be there to realise the designs, the day will come when the pupil takes their design home and gets it printed out on the family printer.
now can we please stop arguing with each other and help the OP out, after all as a teacher they have probably seen enough of this behaviour in their classroom.
personally I only have experience of the da vinci, and I agree that this is probably not the best printer for the classroom- mainly due to the lack of support from the parent company, it does work reasonably reliably, but i have chipped two print beds now, that is one a year with light use of the machine, in a classroom environment I can see that repair costs could spiral, and add to that you would be doing the repairs yourself, and it becomes uneconomic, the machine gets put into storage and the class becomes theoretical with no practical. I believe a simpler machine, that can maybe print its own repair parts would be a better learning experience.
When I was at school, 2D printer is where 3D printer is at right now. Dot matrix, inkjet, thermal, and laser jet, very fancy but also with many paper jam or print head block issues. Main stream computer 128kb memory and 800MB hard drive at that time.
No school teach hands on 2D printing in class however, we do learn a lots of 2D design in computer class, and I don't feel we missed any important training. I don't see how it is going to be much different in 3D printing era. I can see more school library provide 3D printing equipment/service in the near future. As the maturation of 3D printer technology, the need for formal hands on 3D printing class is going down for everybody and the time share of 3D design class will increase in school, and not necessary 3D printing oriented.
