Wow, very closed minded of you.. So just because no ones done it successfully must mean that it cannot be done?
Its just not the case, LCD printers will be coming soon. There were technical issues in the past, LCD resolution, Panel cost, color filter issues, LED and LCD technology just wasnt up to it until recently.
Also, I'm not sure where you think UV is a problem, I dont use UV LEDs for my light source, I use 405nm LED's and they passthrough the LCD with no issues at all. Everyone seems stuck thinking its just UV light that cures resin, it is not. Near UV works just as well. Actually I can cure resin faster with my LCD vs DLP.
And finally, You want to see a commercial LCD printer, then wait just a few more weeks for the Kast printer to come to kickstarter. While I would have liked it for it to be me who made the first LCD 3d printer available, I just didnt have the resources to do it quickly enough. I will be releasing my machine before the end of the year though. Ive been working on LCD 3d printers for over 2 years now. I can assure you they do work.
Heres a link to the Kast machine.
