  • As someone who does R&D testing on plastics that are used in medical devices, I have some insight. Of course the type of plastic matters, but all plastics use carcinogenic chemicals during the manufacturing/extrusion process.

    To make most plastic, a polymer resin is mixed with additives such as solvents, plasticizers, and stabilizers at high temperatures. Ideally, you want the additives to evaporate out during production so that you’re left with just the newly formed plastic.

    But some of these additives get trapped in tiny air pockets between polymer chains. When they’re reheated, the polymer chains relax and release the volatile, carcinogenic additives into the air.

    This is likely where the toxicity is coming from, not the polymer chain itself. So regardless of the type of plastic used, reheating the polymer during 3D printing will release some volatile additives.









  • Agreed. We need to take it up a notch. If you’re getting a permit for your protest, it’s not really a protest. It’s a parade with signs.

    Protests should be against the law, even peaceful ones. Things like peacefully sitting in places deemed illegal, creating human chains around eco-destructive & heavily polluting machinery, and destroying harmful oil infrastructure.

    The elite will argue that destroying their property is violence, when it is really an act of self-defence. We are an intelligent animal species that comes from the Earth. It is part of us. The same way that your skin cells, and the tissues lining your lungs, make up who you are.

    We need to start defending ourselves against the cancer that is capitalism. This is a great staying guide: Eco-defense needs to be popularized.
