I have seen it, and calculated the output power based on the LED, which is very low. At best maybe 40 Watts? You could build your own like it for half the price if your interested in something like it, I mean truly that is NOT rocket science.
Or if you can hold out till just after the New Year, I can offer you up one that is similar with 120 watts of the right UV spectrum and is built much more solidly. Not really trying to pimp my stuff, as its still in the development phase...but models will be ready to ship after Christmas. Its basic yes, but will burn a solid screen for the money. A vacuum lid is coming, a compression lid will be on the first to ship. Simple on off power switch, use a handheld timer for exposure times...there is no need for a "light integrator" as mentioned, its perfect UV as such all you need is a timer.
This is a mock-up model to show how the layout is. For a 20x24 screen. This will be priced in a similar range as the Maple Print models.
