Hey @Mojeska
It brings us joy to hear that there are more and more schools adopting STEM and STEAM programs. Those kinds of programs are what got some of us through school!
I like to recommend the Creality machines like the CR-20 as they are really cost efficient and for the most part simple to use.
The CR-10's are always a good choice as well with them being more basic in terms of options. Our Sales team does know where schools tend to lean to in terms of printers better than I do though. I might recommend to give them a call for just gathering information.
