PLA is made from corn, sugarcane and other plants. Don't get it twisted.

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...
tbf what matters here more is microplastic production per capita rather than overall production
That is what's referred to as 'a distinction without a difference'.
what's your opinion on private jets?
Nobody should have a private jet
How is that relevant to the topic of microplastics? Outside of tires, which again — see my first point.
Which is much lower for 3d printers, than it is for cars :3
yeah probably, im not debating that (open source 3d printing is one of the best innovations in recent years fight me)
Tires are the 2nd largest contributor to microplastics in the ocean. Synthetic fabric like nylon, polyester, etc. are the main contribution.
And the majority of that is fishing nets. I’ll keep my printer thank you.
Aw man there goes my all polyester 70's wardrobe!
Insert scroll of truth meme here.
what happens to be the highest?
Your mom.
everyone's, really. if its even been found in mariana's trench, of course it's in yo mamma's trench too.
UsernameHere has it right below you love
Tires are made of rubber though.
Tires have suspended micro plastics in the rubber, and small particles of rubber are still under the 'micro plastics' umbrella as a synthetic plastic polymer, glad you have such an understanding
Shouldn't those be micro rubbers and I'm not talking about my condoms.
Do you rather have me buying a complete new device than printiner a spare part with PLA (not derived from oil)?
PLA is basically plant starch. most 3d printing is done with PLA
made from doesn't mean same properties (e.g. biodegradability)
It's biodegradable in an industrial composter, and degrades in sunlight. Sure it's not perfect, but compared to everything else its impact is minimal.
PLA doesn't not hold up to the elements. sunlight breaks it down
it turns to floppy noodle in summer heat
do you even know anything about PLA?
sorry for spez site but here you go
I use PLA all the time and I get that it degrades in sunlight, but every fucking plastic does. Degradation isn't decomposition and you can still enjoy 3D printing while understanding that it's not 100% environment friendly
Look, you see the world around you? You think it’s worth saving? We had a good run, time to burn it down
Think of the animals that preceded us. Humans are so self-absorbed.
I’m hope you held a pinky up as you typed that so you could get the full “I’m better than everyone else” experience
yes my 3d printer is the problem, not factories or corporations.
What do you think the net pollution of Luigi's alleged Glock and suppressor print is, all things considered?
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.
