We’ve all heard stories of the dangers of 3D printing, with fires from runaway hot ends or dodgy heated build plates being the main hazards. But what about the particulates? Can they actually…
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’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.
Phytoplankton are microscopic plants that, just like plants that live on land, require access to the sun to survive through the process of photosynthesis (turning sunlight into energy using chlorophyll).
Zooplankton are microscopic animals that feed upon phytoplankton to survive.
These tiny creatures do not have very long lifespans (a few weeks at most), so they are reproducing and dying at a very rapid rate. When these microscopic creatures die, they sink to the floor of the ocean.
Over time, the plankton are buried and mixed underneath layers of sand, silt, and rock. This process has occurred since these creatures evolved over 1 billion years ago and continues to this day…
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.
FDM plastic often uses PLA, which is derived from corn starch, not petroleum.
So this is just propaganda.

You have a bad understanding of science.
Plastic is a very broad term for materials made from synthetic 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.
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.
