Not trolling. Genuine question.
I don't care about "winning an argument" and I ABSOLUTELY don't want people to be scared of these machines. They're fun and any piece of equipment is completely safe so long as you know what you're doing. But I would just like to get some concrete facts if possible for my own piece of mind and to put our hobby into proper perspective.
As a consumer it's been very difficult to scrounge up definitive facts about the health effects of resin. Almost every scientific study must caveat it'self with "May lead to" "Has shown signs of" or "X, is not yet fully understood". That's just the nature of studies. They can't deal in absolutes of "Yes" or "No".
I am interested to know what the main difference is between traditional resins such as fiberglass resin, urethane resin, and other casting resins. Because I know for a fact that many of them DO emit hazardous fumes. They say so on the can and advise you to wear a respirator and eye protection because of it. Many people are saying respiratory protection is unnecessary with printer resins. I realize the UV resins are not the same but for the sake of knowledge I'd like to know in what ways.What is the actual science behind it? What are the biological effects if any? You have the floor if you know the answer and it would put an end to all this petty back and forth. How are those other resin fumes hazardous and most 3d printer resins not?
Speaking only from my own experience, I print in a non-ventilated garage (yes I'm working on that don't worry) and many times have noticed that my throat is irritated if I stay in there too long with the resin printer running. As a result I have to open up the garage and circulate the air pretty frequently. And no it's not "mold in the garage" because I've observed this in my last place too.
Just for the heck of it I saw my doctor who referred me to a toxicologist. I explained all about the resin and showed them what I use. The toxicologist didn't seem to have any clue what to tell me. Just sorta sent me off with a "Yea there's not much data out there."
So yes I went to an actual doctor. The only doctor anyone could think to recommend and they had no idea. So any rational person upon seeing that nobody has solid answers would just err on the side of caution. Especially when it takes almost no effort or money to do so.
