Unserious are your source choices my man, everyone can invent their own truth. Not much more to say tbh.

thankfully I do not have cause I actually am an eastern european.

I encourage you to go to Russia and check yourself, maybe ask a few Russians. Hopefully you end up on the frontline pretty fast and stop posting shit like this.

Or at least maybe go to some post-soviet country and ask the elderly how great it was under the communism. Those who survived it of course.

It does have some AIness to it, but I agree with other comments that it is most likely not. Maybe AI enhanced or sth

Ender's game kinda shit

Polish would probably be "Mieć wyjebane", which comes from "Mieć wyjebane jajca". It is also balls-related but more like "I have my balls out for that".

I see, to be honest I have not checked how clean it actually is. It is visually transparent, as opposed to the used one, but you are probably correct.

What I do is just expose the dirty isopropanol to sun or UV in general - the resin will precipitate. Then just filter it out and you have clean isopropanol.

Wow, so many bullshit points there it is hard to even start discussing them.

And this guy does not even touch the actual problems the wind turbines legitimately have.

Impressively ignorant.

They look like air bubbles to me, but it is weird they only come out after the bath. Could be they were already inside, but only covered by a thin wall of resin.

I usually use Isopropanol for bath not Ethanol, so I am not sure how your resin reacts with that. The bath should also be rather short, like 1min or something.

A few things to try:

• If you are shaking your resin before print, then give it like 10 minutes after you pour it into the vat, so all bubbles come out and pop
• lower the print speed
• add wait times between the end of lowering the plate and light on
• try to hollow out the model if possible, so there is less printing volume

My point was that if they would be trying to forge the results, they would likely write a better paper. Like, I have never seen nor would I use a phrase like:

Humankind has long learned that the properties of matter stem from its structure.

or

It is the superconductor with the same color as typical superconductors.

in the results section. It just reads like a student report.

So while it does not prove whether it is correct or not, it, at least in my understanding, indicates that it is genuine. The explanation might be off, the important step of the synthesis might include adding a teaspoon of luck, but the observations/measurements part I believe. Which is what I meant by the comment.
