Headline: > Commercial 3D printers emit [...] Next paragraph: > [...] emitted from consumer-grade 3D printers Now what? Commercial or Consumer devices? Sorry, can't take this really serious if there's a mistake like this directly in headline/teaser text.

Maybe it's "commercial" as in "sold as a complete product" as opposed to a DIY printer using the RepRap firmware or similar ?

do you have more info? I googled but didn't find anything relevant

Can we please refrain from citing sources mechanically unable to determine the orifice from which they are speaking?

ChatGPT will happily spout the most inaccurate crap possible, but it is difficult for anyone but an industry expert to analyze it case-by-case. It's the antithesis of the HN standard of quality.

Anything following: "I have no clue what I'm taking about, but the following sounds reasonable:" isn't worth the weight of the photons used to transmit it to my device.

The chemicals used for resin printers make this look benign.

Use a straight up gas mask, lab goggles, and nitrile gloves with mine at a minimum. It's nasty stuff

I basically channeled my days working in pathogen labs - "hot" surfaces where resin ends up, respirator, goggles and gloves, etc.

The human nose is an extremely sensitive chemical detector, and should not be dismissed. It's effective down to a fraction of parts per trillion for certain chemicals. https://en.wikipedia.org/wiki/Odor_detection_threshold#Odor_...

But for others, like carbon monoxide, it is useless and leaves you to die.

That's my usual line when people talk about smell being indicative of how safe something is.

Farts smell. Carbon monoxide doesn't.

Let me ask a dumb question: is this stuff more or less toxic than breathing sawdust or working on a car?

I wouldn't do any of this stuff inside the living areas of my house, but I do lots of stuff that is probably at least as toxic as this in my garage.

My go-to example is using gasoline to clean my hands of grease after working on the car. This was a bog-standard thing when I was growing up.

Resin printing is neat, but it's strictly in the "do you have a garage?" category for me. I do not have a garage, so I do not have a resin printer.

meh, just crack a window. if it's good enough to fool mom&dad that you're smoking in the room, it's gotta be good enough for expelling noxious gases like this too, right? /s or the people that spray fragrance to cover up smells as if that's actually removing the issue rather than just covering it up. lighting a match wouldn't be a strong suggestion either ;-)

I love those spray air fresheners. Aren't they just an agent that numbs your smell receptors so they stop working and therefore the smell goes away? If so, I KNOW a software engineer was behind that product.

I recently purchased a 3d printer, and I looked for articles talking about the risks associated with PLA fumes. This article[1] seems to be popularly cited, which includes the statement "PLA doesn’t look like a problem." I think this is what in my experience has been largely the sentiment when I have asked around, and read forum posts about the topic. At my local library there is a makerlab space, they are free to us…

IIRC, enclosures aren't common on consumer models because there's a patent on that design. Not sure if the patent has expired or not but with the trend already in motion, consumers are accustomed to open air printers. Printing the parts for an enclosure is also a good way to break in a new printer.

Yep this prevented any commercial options. It's why the Ikea Lack became so popular as an easy and low cost enclosure to make - I've got one for my Prusa Mini+ and it obviously does nothing to help with venting.

People are saying 'ventilate'. Makes sense. I've got a resin printer in a large room with a crossbreeze, but I'd like to put in some more forced ventilation. Is there a quick thing I can buy that's got a small hood, inline fan, and waste vent? Or do I need to cobble something together myself out of flexible tubing?

Is a portable hepa filter sufficient? I don't even know what to look for.

no, i think you may be thinking of Axe body spray. i think they numb more than nasal receptors though
