Its Native Resolution is 320 x 240, which is on the small side. It also uses a LCD, which most likely won't transmit much into the UV wavelength so you may need to use a resin that can polymerize via wavelengths greater than 410 nm.
I prefer to know nothing about everything rather than everything about nothing. :)

I too have been looking for my project LCD projectors printer, and from what I have read out there at a good resolution of a minimum amount of lumens 2300lm and after 10 seconds of exposure it would go sullo 3000lm or more, so I decided to make the laser printer, DLP projectors sodium lamp 3000lm are very expensive for me.
