Fuck Trump and Musk, but seriously, this comic is just shit. Whatever you people call communism in the US has nothing to do with what actual communism was or is. The communism had its elites and whoever claims that people were or are equal under communism is just an ignorant. And, most importantly, communism in Soviet Union was just a brutal regime which silenced the opponents by killing or torturing them.

That is only sort of true - this image is not made of electrons reflected by the nuclei. These are results from TEM imaging, so Transmission Electron Microscopy. The electron detector is placed behind the sample.

What you are describing is SEM - Scanning Electron Microscopy - in that case, the detector can be placed above the sample, for example (but not limited to) circularly around the beam to measure the backscattered electrons

In TEM the samples are cut into very thin slices (in the picture you posted it is said to be between 0.8nm - 30nm) and the crystal lattice acts as a diffraction grating for the electron beam. The diffraction pattern can be then used to reconstruct the crystal lattice structure.

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
