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.
Please make sure Form Labs, and the rest of the companies I have worked for, are aware of how wrong their engineers are.
I'm not sure what the obsession is with arguing against the list of objective facts I have provided - each argument peeling away into a deeper and more obvious lack of understanding...
Please feel free to run anything other than the recommended wavelength of UV light through a photoreactive polymer resin and let me know the dimensions of your resulting print. Remember to do it twice, so you can compare the results - the point of this discussion. Repeatable results, to 1 micron of accuracy.
(your repeatable result will be a measurement of thin air, as your print will not cure - but feel free to try, as I've said.)
I couldn't find official dimensional accuracy specs for any formlabs machines except the 1, which lists 150um. Perhaps you're talking about the 3, which has a specified minimum spot size of 85um according to this paper. Where did they claim micron dimensional accuracy?
I don't care what the specs of the printer are. This is a discussion about repeatability.
I can get sub micron repeatability out of playdough with the right extruder and hardener. Every single one of you has been arguing from an entirely false premise to begin with.
