  • Avoid and mitigate fumes. Buy a jug of D-Lead hand soap and laundry detergent and use it. Get regular blood tests for lead levels.

    If you have or are regularly around small children, you need to be extremely diligent about the above. That goes for all you idiots obsessed with guns as well. Primers use lead styphnate and create lead vapor everytime you fire. Worse with rifles because your face/body is closer to the expelled gases. Aside from breathing it in, you’re also getting a nice patina of lead residue on your arms, shirt, face, hair, etc. You’re also likely tracking in lead residue from your shoes into your home. If you like to hug your kids or your kids play on the floor, guess what.

    Do NOT fuck with lead. There’s no safe level of exposure, and it can be devastating to the developing brains of children.










  • I had a friend that was drunk and was smoking and leaning back on a balcony and went over. No one even heard him. One minute he was there, the next minute he was gone. No one even looked down for a few minutes because people were regularly coming and going from the balcony and people just assumed he went back inside.

    Broke both his arms, his neck, fucked up his back, and had a major concussion. I think maybe he broke some ribs too. Really fucked him up. He didn’t die, but the head injury caused a dramatic personality change and the neck and back stuff created chronic pain.

    Another guy I knew intentionally jumped off a dorm balcony and severely and multiply fractured both his legs and fucked his knees forever.

    Don’t… uh, accidentally drop from great heights, people.




  • 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.
