Wow who would have thunk the chemicals getting dumped into the environment by the fucking oil industries could be dangerouse. There are a million 3d printing materials u can use and have decent extraction and ur fine. Guy u need to be scared 3d printers might give the consumer too much power, cant have foss technology winning out.
FDM plastic often uses PLA, which is derived from corn starch, not petroleum.
Okay buddy ya wanna get specific? Let’s get specific. Sea creatures are made up of protons and neutrons. So was Hitler. Coincidence??? Checkmate? Nah we aren’t done yet buddy.
What are protons and neutrons made up of? Quarks! You know what else is made up of quarks? My average sized penis.
Do you think my penis is considered safe? What about sea creatures? I think you have a lot of research work to do in physics and polymers.
you have given me a lot to think about
An average sized amount to think about.
I would say it's actually only a small amount to think about.
I have no horse in this race but this shit made me ugly laugh.
You're not wrong, but the idea that "plant based" is "safe" isn't right either. Plants can create all kinds of horribly toxic, carcinogenic compounds -- especially when burned or heated.
Wood smoke of all things is mildly carcinogenic and we cook our food with it.
If you had read my comment, you’d see that I never said nor insinuated that PLA was safe. I specified it differed from petroleum.
Petroleum comes from crude oil. Crude oil is the remains of the first forests. Where did you get this idea that it comes from sea creatures?
Coal is from forests. Oil is from photosynthetic aquatic life.
You're both wrong, but you're half right. I don't understand how the ancient forest guy got the upvotes, because he's completely wrong.

Coal is from ancient forests but of a different age (400 million years ago) and it also required wetlands and aquatic life. There was for sure an element of micro life that was involved but photosynthetic aquatic life is only a factor, its not really known exactly what exact factors are determined except time heat and pressure. It would be more accurate to say that zooplankton, algae, and bacteria are what made crude oil.
