If you’ve ever used resin printers, you know the cartridges are a good thing because the liquid inside is basically carcinogenic if it comes in contact with your skin, so a lot of people just don’t do resin printing for exactly that reason and this gets around that.

Except you will have failed prints (for me it's 1 out of every 20 with my form 4 with the kinds of parts I tend to print), which will require taking out the tank to clean obstructions and free-floating debris... and when you're having to filter the resin (like so: https://www.youtube.com/shorts/UdX94R3k7YU ), it's exceedingly hard to not get it in contact with your skin.

I think they’ve considered a lot of these problems from the perspective of handling resin when they designed the system. The vapors are carcinogenic too, so they have an inbuilt air filteration system. The whole washing and UV curing stations can be done without ever having to touch the resin. I guess I don’t know what happens in case of a failure and how you have to deal with the pool of resin in the bottom of the plate even after a successful print job.
EDIT: So I looked it up a bit more and it seems like in the case of failed prints. If you want to clean out the resin, it does have a partial solution that helps you print out a cleaning sheet to capture all the debris so you may not have to do filtering also after a successful print, you can just leave the leftover resin in the tray that does not need to be dealt with.
