This study looks at how particles released from 3D printers (specifically using ABS and PLA filaments) can damage cells and potentially lead to cancer. They found changes in gene expression linked to cancer development, but they can’t definitively say 3D printing causes cancer yet.
If you read the full study, though, it’s clear that exposure to these particles affects cells in ways that suggest further research is needed to figure out just how dangerous it is, not if it’s dangerous. The study avoids outright claiming that 3D printing causes cancer because it was mainly designed to assess cellular responses to particulate exposure, not long-term cancer outcomes.
They did see cellular changes linked to cancer pathways, but the study’s design didn’t allow them to draw that direct conclusion. A follow-up study focused on these gene expression changes and long-term effects is likely to show a clearer link between 3D printing exposure and cancer development.
That being said, this isn’t the only study. For instance, particles emitted during 3D printing—especially ultrafine nanoparticles—have been shown to cause cellular damage, oxidative stress, DNA breaks, and inflammation, all of which are early indicators for cancer development. In one study, exposure to ABS fumes led to a 49.5% decline in cell viability, pointing to high toxicity levels.
Other research has suggested that people exposed to 3D printer emissions have a cancer risk 3.44 times higher than those exposed to typical urban pollution. To be blunt, it’s pretty well established that the particles emitted from 3D printing processes are biologically active and harmful. I think that most people engaged with the hobby probably know that intuitively, which seems borne out by the tenor of many of the comments here.
It’s dangerous, and it’s likely shortening your lifespan in the long term. You might not care now, but if you get cancer in a decade or two, I imagine future you will feel differently. “Do you” and all that, but I’m amazed by the amount of people 3D printing without air filtration and vent hoods. The fact that some people do this in the open air in their living spaces is mind boggling to me.

You’ll be OK.
Everyone else: “The microplastics are killlling usssss!!1!”
3D Printer people: “I love the smell of carcinogens in the morning.”
They still include landlines, but no major polling agency in the United States has used landline contacts as the primary source of polling data in at least a decade.
As you yourself note, landlines are wonderful for sampling particular demographics, which are then weighted against local, county, regional, and national demographics (to name only a few of the analytics used).
Do you think polling is just some guy smoking a cigar yelling at a room full of people dialing furiously on rotary phones to old people, and that’s why Trump is polling ahead?
No. He’s winning because majorities of likely voters are going to put a narcissistic fascist in the White House because they’re mad at things, and Biden has continued to lose astonishing numbers of non-white voters.
That should scare you, if you care about the United States falling into fascism. The US is a technology, nuclear weaponry, military, and economic superpower. The world’s economy runs on the USD and the United States has 800+ military bases in over 70 countries. That alone makes it a concern.
Whining about the polls won’t change that.
That’s not how modern polling works.
Oh you weren’t personally involved? Then it’s probably fake news. Where have I heard that line of reasoning before… hmmm.
ITT: poll denialism about the least popular president in modern history. The rising prevalence of poll denialism by democratic voters is the biggest indication, to me, that were in very serious trouble.
If wishes were fishes, we’d all swim in riches. Just because we are sleepwalking into fascism doesn’t mean denying what’s happening helps. At all. Quite the opposite.
I imagine you probably don’t become a billionaire by just letting people force you to pay your “bills,” or by following “the law,” or by caring about “people,” or by responding to ethical “responsibilities.”
Probably you become a billionaire by doing the opposite, but idk

It’s a perfect wedge issue to cleave voters away from Biden. He’s the least popular president in modern history and democrats have lost substantial support from people of color more broadly. He was likely to lose before this. He’s more likely now.
Democratic poll denialism is a sure sign we are in serious, serious trouble.
Edit: the fact that people downvote comments stating basic facts about a) the unpopularity of Biden, and b) the rising unpopularity of democrats among people of color is exactly what I’m talking about. We’re in serious trouble.

Republicans have become the party of “if we don’t win it, we’ll take it.” And democrats have become the party of “but we have to win! I don’t want to look at anything that doesn’t agree, and I don’t want to have to do anything about it except downvote!”
I’m straight up terrified.
I’m not collecting all Jewry and describing what they do or do not believe, for one! I’m saying that being Jewish isn’t only about participating in a religion. And I’m also saying, which underlines my previous points, not all Jews think the same or believe the same thing.
Are you Jewish? Are you Palestinian?
To disagree with the basic point that all people, regardless of classification, don’t believe one single thing is ridiculous. To what are you even trying to retort?

The fact of the matter is that democrats are betting it all on the least popular president in modern history, who is also an octogenarian. The hope is he will somehow be disliked less than cheetolini.
The problem isn’t that democrats are going to vote for Trump. The problem is that polling indicates that Biden is already losing, so every person that decides NOT to vote for him by staying home or voting third party is just another nail in the coffin.
Biden deciding to run for reelection is the presidential politics equivalent of Ginsburg refusing to retire. And it’s right there in front of us. And we know it’s insane. But now everyone is just knuckling down and buckling up, because here we are.
Jews “aren’t supposed” to support or oppose anything as a monolith. That’s just racial essentialism.
It seems to me the point is that mail-in ballots are often added later in election results. The RNC is reallocating their budget to legal challenges. This seems to anticipate two things:
- the idea that mail-in ballots are corrupt will continue to be pushed. The “proof” will be how many more democrats there are in the mail-in ballots, partially due to the RNC attempting to minimize GOP mail-in ballots.
This will be informally reinforced by calls for armed Republicans to “stand watch” (aka voter intimidate) at ballot locations. This will disincentive in-person voting from democrats and increase the chances that mail-in ballots will seem partisan.
- based on the actions of #2, on election day live votes will be tallied first, ideally showing a GOP win based on the idea the hope that more GOP will vote in person.
GOP will then immediately declare victory and try to delegitimize mail-in ballots as they begin to be counted and are “suspiciously” (intentionally) largely democratic ballots based on the consequences of #1.
Then they’ll try to sue to win by attempting to invalidate all mail-in ballots as “irregular,” which they will be, because the republican party will have attempted to make them irregular.
Mostly having both my eyes and modern hygiene.
