Please, use heat exchangers if you’re going to be resin printing inside. I don’t want to see all of you guys get cancer from this hobby.
Explain what you mean by use heat exchangers?
Resin Printing is killing you.

Yeah the term “heat exchanger” describes a lot of things.
CmdrShepard@lemmy.one 9 months ago
Okay I pulled the radiator out of my truck buy I’m not sure where to connect it or how much coolant I need to pour in my printer.
thantik@lemmy.world 9 months ago
It’s essentially a heat/cooling recovery unit so you’re not simply pumping your A/C out into the world and wasting energy. It allows you to swap the air in a room out, without losing its cool/heat by simply pumping in outside air. The video explains what he used.

Probably an ERV or HRV for ventilation.

Yep, it’s basically a simple air-to-air heat exchanger.

He says even as a trained chemist, he does not understand resin completely and its full risks.
j4k3@lemmy.world 9 months ago
Thanks. I’m no expert at this chemistry, but this is the better reference IMO

Even if you're printing with anything but PLA, you should be ventilating well, since it obviously releases chemicals into the air -- you can smell it. PLA does as well, but from the smell it seems like a much different one.
RobotToaster@infosec.pub 9 months ago
PLA is used for medical implants, because it breaks down into lactic acid inside the body, so it’s almost certainly safe.

Sure, but you still shouldn’t inhale it.
PeleSpirit@lemmy.world 9 months ago
He explains why the carbon filters don’t work, how he mitigated the problem and he really suits up.

What is the correct way to ventilate the 3D printers? How can you ensure accidental contact with resin won’t ruin your life?
thantik@lemmy.world 9 months ago
The correct way is basically this: Get a ventilation fan, and exhaust the air around the resin printer to the outside of your home. Learn proper safety procedures, with correct nitrile gloves, and VOC-rated respirator and use that to ensure you don’t get resin on your skin. Resin print in the garage if possible. Resin likes warmer temperatures anyhow, it helps the chemical reaction occur.
An upgraded system is going to cost more, but if you’re in an air conditioned area - it will save you air conditioning costs. You need a heat recovery ventilator, and typically that will come with 2 blower fans, this isn’t absolutely necessary but would be the “correct” way to do it. I’d opt for this if you’re resin printing inside your home office and it’s going to be a permanent thing, or if you’re running lots of resin printers at once.

Fuck this video. Dude claims it’s killing you and offers zero reason as to why or how. Pure clickbait bullshit here folks
Carighan@lemmy.world 9 months ago
Also leads with “It’s not clickbait”, **then it is very very evidently clickbait. Really the peak of modern Youtube scum.
sebinspace@lemmy.world 9 months ago
To be fair, this is kind of the environment YouTube have cultivated over the years, intentionally or otherwise
NBJack@reddthat.com 9 months ago
Did you actually watch the video?
He literally presents a list of reasons around 5:12. Then he goes on to describe how formaldehyde already affects him.
Resin priting can be a lot of fun, but he’s correct: that shit is toxic. It needs to be respected, and he’s also correct in pointing out the carbon filter on many printers is basically a placebo for the consumer.
Still don’t believe him? Fine. Go checkout the small book that is the set kf warnings with this stuff from a resin producer: entropyresins.com/safety/epoxy-safety-tips/

thantik@lemmy.world 9 months ago
He mentions VOCs within the resin, just because you can’t wrap your head around why “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.
RobotToaster@infosec.pub 9 months ago
Perfume and air fresheners are VOCs, you need to know specifically what ones.
Carighan@lemmy.world 9 months ago
Oh, we’re supposed to read the manuals now before handling chemicals now?!
newIdentity@sh.itjust.works 9 months ago
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
It doesn’t say shit about how bad something is for you.
