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.

He mentions VOCs within the resin, just because you can’t wrap your head around why inhaling “volatile organic compounds” can be bad for you, does not mean it’s wrong. Take proper precautions to ventilate the area while printing resin, please.
You know volatile just means it readily evaporates, right?
Alcohol is a volatile organic compound.
Nothing about the term ‘volatile organic compound’ means dangerous. You need more information.
Even when you cook food there are volatile organic compounds all around you and nobody would say they’re dangerous.
Perfume and air fresheners are VOCs, you need to know specifically what ones.
Oh, we’re supposed to read the manuals before handling chemicals now?!
I’ll check the manuals after mixing up this sweet bleach and ammonia cleaning spray.
Mhhh, clorine gas
It really helps freshen up the sauna if you got a bad smoke draft. Just removes the smoke smell immediately. If you pour the mix on the hot furnace you are golden
“If my calculations are correct, this will create ice. Oh no, killer mustard gas!”
You clearly have no idea what that even means.
When you cook food there are voletile organic componds. Almost everything you smell are voletile organic compounds. Parfums are voletile organic compounds. Your air is full of voletile organic compounds.
It doesn’t say shit about how bad something is for you.
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.
Basically everything that has a smell is a VOC. If it wouldn’t be volatile it wouldn’t have a smell. Something being volatile alone doesn’t say anything about it’s toxicity.
Something being organic also doesn’t say anything about toxicity. Your whole body is made out of carbon. Something being an organic compound doesn’t say anything about it’s reactivity either. That’s simply not how it works.
Something being a polymer also doesn’t say anything about it’s toxicity. Proteines are polymers. DNA is a polymer too and neither are particularly toxic. Polymer just means that’s its a structure that repeats itself. Poly = multiple, mer = parts.
Everything you said doesn’t say anything about toxicity. Toxicity depends on the individual compound. Even small alterations can make a harmless molecule toxic.
All VOCs are reactive. VOCs range from “Known Cancer causing effects” to Mildly harmful, but VOCs are considered harmful. At the ranges presented in the video, they are immediately harmful. If you wanna go huff your resin, you deserve what’s coming to you. I’ve talked to Resin chemists (mostly through the 2019-2020 Midwest RepRap Fests), and they agree with most of what’s in that video. Go ahead and get mad about things if you feel resolve in doing so. I’ll continue warning people of the dangers.

Nah. It’s just that the reasons he mentions are simply not true. Resin fumes are harmful, but not because they are VOCs or because they’re polymers. He tries to make it sound like he knows what he’s talking about when he clearly doesn’t
Yeah, you’re right. They’re right, but they’re not right about why they’re right.
I had no idea reskin could cause serious injury with mere contact. Why is it so dangerous?
Resin typically has chemicals which are auto-immune sensitizers. The more often your immune system comes in contact with them, the more strongly it reacts. You could be one of the lucky ones, and have it contact you a hundred times and nothing happen too drastic other than dermatitis. Other people have gotten it on them a handful of times and are now highly sensitive to it (I’m one of those).
