Anyone got any updates with there attempts with Daylight resins?

Received my mini dp to dp cable today and had about 45 minutes to play around.

Ran some 3w 470nm blue leds through the ipad screen with what I think were the 3 filters closest to the screen to even the blue light out. When the screen was 35-40mm from the leds it seemed pretty even. Only had 6 leds wired up.

Had an epiphany today with testing resin. On the earlier tests the thick blobs would cure first. Oxygen inhibition in effect folded the plastic over and sandwiched the resin and it all worked a lot better. Cured around .2mm thick in around 10 seconds. Nothing to scientific though

Tried it this afternoon. Unfortunately the second screen backlight has an issue on one side of the screen. I was still able to try even after breaking the locking bar on the FCP connector on the abusemark board.... Seemed to cure just fine in the 10-20s. Still a bit hard to say how this will translate to actual usage cure times, but encouraging. Unfortunately the screens aren't as cheap in europe as they are in the US for some reason (2+ x as much!) so I'll be waiting for a new one from china. Probably give up on the blue leds for the time being.

Right now I'm thinking the biggest question in all this is what is a reasonably priced method of getting displayport output. For mucking about my Surface works great but I want something dedicated for the actual printer.

Yeah the converters can be expensive. You either have to go with HDMI->DP or USB3->DP converter. Not all of them will work, so you have to be careful. Seems the cheapest for either of these is in the $40 range. If you have a desktop just buy a $20 used graphics card on eBay that has display port.
