Elon Musk says ‘we dug our own grave’ with the Cybertruck as he warns Tesla faces enormous production challenges::Tesla CEO Elon Musk said Wednesday that the Cybertruck’s unique design means the company faces immense challenges in scaling production.
Sigh.
Please stop being confused about the capabilities of modern SLA/DLP processes.
What is the diameter of A PHOTON? And don’t forget to answer ignorantly, in a condescending i-know-more-than-my-betters tone. No, seriously - look it up. You clearly don’t know.
How many blood cells wide is light? By all means - tell me what the particulate size of photocuring resin might be? Could it be…2 microns maximum even for the largest ceramic-infused resin slurry - with sub-micron particulate sizes easily available even from Amazon? Yes - far, far smaller than blood cells. This is why you can’t let this shit get on your skin. It will literally traverse the blood-brain barrier. The fumes can get particles of this size into your bloodstream.
Well, what on earth can I do to get 1 micron accuracy from zero-width photons and 2-micron UV cured particles? Perhaps - design my model to be LITERALLY ANY SIZE that happens to be divisible by 2 on X, Y, and Z axes, then center it on the build plate?
Can you please get with the program, here? I’ve likely been doing this work longer than you’ve been alive. I’m not even supporting Elon’s demand, which is almost certainly unnecessary for this application.

Thanks for giving me more absurd examples. Your UV light is a 400nm wavelength or so. Or roughly 1/3rd a micron. The fucking wavelength of your curing light.
Now get outta here with your attempts at pretending that your $200 UV printer has the level of accuracy of three fucking wavelengths of the light it’s using.
The size of the color red? That’s 700nm wavelength, or 0.7 microns. Your resolution that you’re printing here is no where close to the size of red-light photons.
zero-width photons
Oh, so you don’t know how light works either. Good grief man… light has a size and you’re running up against the size limitation of the light itself. Especially because I know for a fact that these UV Printers are NOT using lasers, so you have no way to actually line up all the photons to hit the same location since their wavelengths are all unaligned.
In any case, car parts are not made at scales comparable to the wavelength of infrared light (ie: the “size” of a infrared-light photon).
Shocking narcissism, yet again.
You clearly have no intent to learn from your mistakes and pollute your entire argument with ad hominem and every other logical fallacy in the book - all wrapped up with a bow of dismissal of the original premise.
Oh, and by the way, light is both a particle and a wave. “light has a size” - indeed, the wave of light we aren’t talking about has a size - called wavelength. Don’t be afraid to use the most accurate terminology for your irrelevant responses! The wavelength has zero influence on the dimensions of the final product, as any wavelength more than a couple nm out of spec won’t cure the resin at all, and there will be no object to measure. I think you know that and are just trying to win an argument by talking over the heads of the average readers on here - which doesn’t help your case.
It’s extremely likely you legitimately have a personality disorder, and are capable of much more if you clean up your act.
Wavelength has a very direct impact on the resolution you can print because it’s an optical system. Under perfect conditions, it’ll be diffraction limited, which is typically anywhere from several hundred nm to tens of microns. That’s an ideal system though, you’re actually going to be getting a dimensional accuracy somewhat above that in practice, probably tens to hundreds of um.
