Everytime i come across a 3d printing post

Even if you personally decide 'auhh my micro rubbers' a tire isn't a solid block of rubber, it has structural enforcement that is plastic, and both of these polymers, when under 5mm, is micro plastic by definition
5mm what's that like ten inches?

You must live in a city, elitist.
I live in the woods but yeah WOAH what's this button I just found it's almost like magic blocked

Tires are made of rubber though.
Rubber, including natural rubber, is a hydrocarbon polymer and should probably count as a plastic in any useful definition of the word for this context. Normally natural rubber is biodegradable, of course, but we vulcanise it for usage in tyres, and that makes it much less so. As such, tyres are a huge source of either microplastic pollution or, if you want to call it something else, functionally-identical microrubber pollution

Yeah, fifth grade
Don’t feed the troll.

Also, the most common 3D printing filament is made of the bioplastic polylactic acid, which is typically derived from corn. Whether that is strictly "better" from an environmental perspective is a fair question.
The only thing that matters is if it’s biodegradable. If the plastic won’t break down naturally, it doesn’t matter if it’s made from starch or crude oil.
Polylactic acid is a low weight semi-crystalline bioplastic used in agriculture, medicine, packaging and textile. Polylactic acid is one of the most widely used biopolymers, accounting for 33% of all bioplastics produced in 2021. Although biodegradable in vivo, polylactic acid is not completely degradable under natural environmental conditions, notably under aquatic conditions. Polylactic acid disintegrates into microplastics faster than petroleum-based plastics and may pose severe threats to the exposed biota.

Do you....drive a car? Rubber rubbing off from your tires onto the road is one of the main contribution (2nd highest) to ocean micro plastics as your tires are filled with them suspended in the tire...

PLA is basically plant starch. most 3d printing is done with PLA

yes my 3d printer is the problem, not factories or corporations.

In my defence they had not posted the replies to others when I had started typing

About a fifth ig?
I'm eyeballing it out.

The fashion industry and the automotive industry are far and away the largest contributors to global microplastics. I'm not even sure if 3d printing people crack the top 100.
The majority of the 3d printed slop people see around is printed in PLA because it's the cheapest and easiest to print typically. PLA will completely degrade in a few months in the correct conditions. At worst it will still break down after a few hundred years.
The more expensive and chemically complex filaments are a different story. The good news is that most people only print "useful" things with those more expensive materials. I have never seen anyone printing a Pikachu toothpaste poop dispenser out of carbon fiber reinforced nylon filament.
Of all the things to be worried about in terms of micro plastics 3d printing really shouldn't bother you. There are many MANY much larger fish to fry in that department first.

The plastic filament I use can be near infinitely recycled and is also biodegradable, while being made from plant resin and not hydrocarbons. This shit will break down before it even gets a chance to be used if not stored properly.

That's fine, just getting ahead of it so you're informed

In my defense, in certain terms, you've got an itty bitty peepee

What do you think the net pollution of Luigi's alleged Glock and suppressor print is, all things considered?
Any 3D printed gun is carbon negative if used to take out virtually any human. People do not live sustainable lives.

Oh yeah buddy you are blocked and I'm delighted, I just didn't want a notification every time you spoke I can still see your messages and contribute voluntarily, love learning nuance of moderation systems, anyway, it's been an honor to hear that when Ur-a-pee-an, your dick is 5mm and honestly, it's been a delightful honor to be gifted this knowledge by one such as you

Sir (or madam) you do realize this is a serious shitposting community right?
