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.

    I know nothing about cyanotyping - Does the heat from the lamp help with the printing process, or just the UV light? If the heat is a bug not a feature, there are some LED products that do pretty good UV light emission. You could do a spectral comparison and some tests and see if you could use those instead, since cutting the heat waste would make it smaller and cheaper and help the components last longer.

    Also this is really really cool and I want to make one.

      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. 😅
