Raspberry Pi 3 Using Internal Wifi Offline

Hello,

I work in a school and our district will not allow us to connect the Raspberry Pi’s to the network. I want to connect my three Monoprice Maker Select V2s to three Raspberry Pis running the Astrobox software. I can’t find any info if we can run it just as a hotspot that students can connect to via their chromebooks after downloading their stl file to local storage and then using the astrobox to load and run the print.

Are you able to use an astrobox still running as a hotspot using the internal wifi?
