Technically these printers use 405nm light which is just outside UVA and pretty harmless to eyes and skin. Though I have never seen an analysis of desktop printers to know how far the light bleeds in to smaller wavelengths, so precautions are still warranted. I just wouldn't be overly concerned about it.
I'm interested in if there was some kind of advantage to printing these at an angle other than testing supports? It would also be nice to be able to find a cleaning tank that will fit the build size of the Jupiter printer. I may be interested in this printer my previous experience was just FDM. thanks
