It's basically a 10 inch screen matrix for SLA printers, a 130W blacklight lamp from Amazon and a ground glass for even lighting. The lamp gets very hot, so the two fans blow air over and under it (split cooling channel). The parts touching the lamp are printed in Greentec Pro Carbon, electronics box and cooling channel are printed in Geeetech matte PLA.
Thanks. Hard to say how long it took, I started exactly one year ago. I first started with a wooden box, but binned it as soon as I got a 3d printer. Then there were alternating periods of CAD, printing and tinkering with the electronics; and this project sitting in a box because I did other things in life. ๐
