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.

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).
