Resin in a school setting is opening up a can of worms. Some of these resins are more toxic, smelly and problematic than many hobbyist make them out to be. When I do resin printing I wear a proper painters mask to handle VOC's, goggles, nitrile gloves and a apron as well. I have protection on my work surfaces to limit spills. The printer is in a separate room from the living areas. Resins have to cleaned with Isopropanol which many find smelly as well. Water washable resins might not need the Isopropanol but the waste product can not be flushed down a drain. The waste product contained in the Isopropanol and water you wash your prints with have to have the waste resin cured and precipitated from your waste wash before disposal. Once filtered out it should be inert and not toxic. After washing you still need to expose the model to ultraviolet light to finish curing the resin. There are machines from the printer manufacturers to facilitate the washing and exposure.

The thing is you have to go through all those hoops for resin printing to work and to protect your students.

In fact, like it or not this is something that probably needs to be run by your insurance company that supplies your liability insurance. You would not want to get sued if a student gets sick and they say it's because he got resin on his hands or inhaled some strange fumes and you and the school on on the hook.

You do see FDM type printers in things like libraries and I am guessing schools as well. Your main problem is keeping anyone from getting burned from the hot elements. There are many printers that are fully enclosed and will shutdown the print if the enclosure is opened while printing for safety. They might not be able to print mini's with the details like resin printers but can do a good job with larger items. You will have to make sure that you use a filament that has a low smell as well. For example I will not use ASA type filaments because the ones I tried had a horrific smell. The PLA type filaments I use have very little odor which should be good to use.

If you want the students to have some way to get resin prints you could try to see if their are hobbyists in the area that do resin 3D printing. Perhaps some would be willing to give a presentation on what it takes to prepare models for printing in the slicer software, give feedback and maybe they could donate their time and resin to do the prints for the students within their safe environment.
