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.
