Yes you can use a different projector, just make sure the projector can cure your resin.
Thanks, well for a larger print area there are a few things you can do, adjust the zoom on the projector and/or increase the distance between the projector and the image plane. Next to that you will then need a larger build platform and a larger resin tank.
Whaaa, you are right, think I helped write some history. Mind blown. Looking back now how far we have come, all of us since then. Thank you for your comment, I had not looked at it like that. Goes to show any one can add something to our collective progress.
Yes, but there are sources that do a much better job than I can https://en.wikipedia.org/wiki/Stereolithographyhttps://en.wikipedia.org/wiki/Digital_Light_Proces...
The build size is dependent, but not reall limited by a couple of things. Firstly, the x,y resolution. A bigger projection means larger pixels. Unfortunately the pixels scale with the build area size. Second is light intensity, the larger your build area the lower your light intensity in W/cm2. There are a couple more but in reality there is not real reason not to make a really large printer

I think that should work, as long as the silicone is flat and transparant enough

Hi YonatanI was most intrigued by your title, but to my disappointment your instructable does not feature any information on emission spectra. You briefly hint towards the bodily response to shorter wavelength light. But it lacks any information on how you are balancing the emission spectrum. Are these leds not emitting blue region light? How did you deal with the dip in the emission spectrum in the green area of the spectrum that usually characterizes these leds?I understand you picked some Warmer colored leds, but how did you balance the emission spectra?
