Potential resolution

Thats exactly what I was thinking! The more fine I get my aperture the more fine I can print one and it then becomes a cycle. Im sure that the accuracy would increase but after a certain point it would be negligible.

There is something very appealing to me about cycles like this. I keep joking with everyone about the idea of printing a record, on which is encoded a "song" which when played into a peachy printer, prints another record.
And of course Im very excited to try printing a peachy printer with a peachy printer (Peachy RepRap) .

I have no clue how well these things work in actual practice but I can tell you that the resin blocks uv light very well. Im sure you can print a large aperture, but i don’t know how small you could print one.

What ever happens be sure to post because others (like me ) will really enjoy seeing the process !

diffraction is the one you're looking for.

Considering that the original subject of the thread was using diffraction to create colored prints, I'm a bit embarassed to not have remembered it.

You've mentioned before though that you can fill a hollow print and it will cure under sustained UV, which would suggest that the cured resin isn't completely opaque to UV. I'm sure it's too opaque to make into a focusing lens for the laser though.

I think most glasses-wearing watchers had the lens printing idea after seeing the column print video. I look forward to running some tests to see what kind of refractive index the resin has and just how smooth it can print with that sub-layer interpolation that was talked about.

I think that it would be easier to write an equation to directly generate lens cross-section based on z-axis and focal point than it would be to make a parametric lens model and use a slicer. The machine that grinds out the lenses for the optomitrist already uses a CNC process that might already be very similar to g-code.
