ok off the top of my head here are some numbers for you:

- laser spot size focused at infinity is 2.5 mm with no aperture ( thats approximately.. its oval looking because the chip that emits the light is actually rectangular )
- we typically print with an aperture between 1mm and .3 mm diameter
- the thinnest wall we have printed is about .2 mm
- we typically print walls between .3 and .5 mm thick
- we typically focus the beam at infinity
- the thickest wall we have ever printed is about 2 mm wide.... actually perhaps ive done 5 mm wide, but that was before the campaign and it was very ugly.

-my intuition ( alto i haven't done this yet) is that if you were to take the basic kit with a .1mm aperture, and place the printer only 2 inches away from the resin
you could get was as thin as .1 mm.

if you leave the laser on in one spot and let the printer drip, you can get shafts that are .3mm in diameter.... the amazing thing is how tall you can make them
I have printed a .5 mm diameter shaft that is 5 inches tall, and it wouldnt be hard to go taller. Its also fundamentally the fastest thing you can print.
