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.
Bullshit.
You’re changing the premise of the question.
Pick a temperature - design your model to be whatever you need it to be at that target temperature - just like every other engineer with 26 years of experience, such as myself.
(by the way, my UV resin printer is quite temperature stable.)
Your resin printer does not have the resolution of 1/15th the size of a damn white blood cell. Your blood is 15 microns per cell or so. Red blood cells are smaller at around 7 microns.
You, and Elon, have confused your units quite significantly. I’ve given you the opportunity to see your error by reminding you the difference between thou, mils, mm, and microns. But apparently you haven’t gotten the hint yet.
My university created micrometer-sized balls, gears, and other such devices. They’re called MEMS and are really cool. They’re not made with 3d printers but instead lithography (same technology as computer chips, because they’re so small its easier to make through lithography). You’ve confused your units and its clear based off of how you’ve been talking. Take a step back, and double-check the difference from thou, mil, mm, and microns.
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).
