Please, use adequate ventilation (with a heat exchanger if you need to keep A/C in the room) if you're going to be resin printing inside. I don't want to see all of you guys get cancer from this hobby.
And the difference being that those VOCs are not specifically isomers which are carrying polymers for additive manufacturing. Volatile meaning they are airborne (or readily made airborne at least, it has to relate to vapor pressure), organic meaning that they've got carbon bonds which readily interact with other elements.
Plenty of people have already suffered anaphylactic shock and other immune sensitivities from coming into direct contact with resin. These sensitivities are permanent. There is no reversing them.
