Resin printing can smell and be pretty toxic too ^^ I hiiiighly recommend you to check out less smelly resins. I have the nova 3d water washable and it is amazing. Barely smell anything, the curing is also 100% simpler and ai can bump the layer time to around 4seconds to even 1.5 seconds. I have no ventilation system, the printer is located at the end of my workung room. It is doing it's job while I am sitting in the opposite corner working at my day job!
