I wonder if you could make a large hand-driven low-resolution 3d printer which, rather than running on filament, had a hopper that you fill with failed prints. Really just a giant hot glue gun.

Honestly wtf does the glue matter when people are going through plastic like it's nothing? Bringing up the glue is such a weird nitpick.
hot glue is a petrochemical just like plastic.

This is also misleading. PLA plastic degrades slowly in the environment because it's highly crystalline and mechanically robust. But once it's fragmented, it's rapidly degraded. So it doesn't contribute to persistent microplastics. It also does not take 80 years in normal environmnets.
Well, my source (quoting some "Federal Environment Agency") says it does contribute to microplastics. Some googling seems to confirm this.
If you care about that kind of stuff the best thing you could do is stop driving.

I'm so glad that fad is over. My mother worked as a theatre artisan before retirement and it was, among other things, fumes from curing epoxy that caused numerous health issues down the line.
I am curious about the down-the-line effects of fumes from printing PLA and PETG. Reddit posts suggest no ill effects, but it hasn’t been long enough in the hobbyist world.
So the author recycled 10 pounds of plastic, but used 8.5 pounds of glue to do so (184 sticks at 0.74 oz which seems to be average for glue sticks). Cool project, but that ratio seems very ineffective. Especially since there is a realistic chance this ends up in landfill within some decades anyway.

barf
vomit even.
One of the most interesting things he said was that the current waste from 3D printing (and other technology) is really a sign of technical immaturity; nature repurposes everything - there is no trash in an ecosystem, only food for something else. Maybe we'll eventually learn to build infrastructure like that.

> Isn’t plastic nearly free as a raw material as a by product of fossil fuel production? Yes and no. Oil is cracked down for lots of different things, but one of the things that people are really aiming for is ethane which can be used to make industrial ethanol, and a lot of plastics. What you end up with to get there is lots of propane and butane, which is used as a fuel gas, but most of that ends up going up the fl…
>What you end up with to get there is lots of propane and butane, which is used as a fuel gas, but most of that ends up going up the flare stack because there's so much of it. We won't stop doing this while we still use plastics and fertiliser. The amount of gas flared globally adds up to little over 1% of global energy production. I know that doesn't sound like much but we're talking like terawatts. It truly is a mi…
It would be great to be able to create "art" and add something that degrades it.
Is this just delayed trash? At some point someone will throw it out. It would be great to be able to create "art" and add something that degrades it.
