I like the idea of a small (cheap) resin printer to dip my (little) toe into a bit of SLA. Like a DIY iBox Nano. Anyone seen any open source ones? Or any useful info (e.g. LCDs that might work, good UV LEDs, build platforms)?

Liam i have same idea and have experience on diy projector and any tft with soft hand can remove backlight and other reflector films. i old 524x244 1.8" screen ready to use…

Nice work, So you used the TFT to produce your own projector?

Ideally I’d like to find a part which can be used stock or with easy modification, I can’t imagine getting the IR filter off an LCD is easy!

yes.

The DropLit 3d printer seems pretty good. Kits available soon i think. Plans available now if you want to make your own.

There’s a couple of projectors you can use unmodified I believe.

@Mauro_Manco Thanks!
@Ben_Delarre I think anything that uses a projector is going to get expensive! I’m thinking of something with under 50mm*50mm build plate. The cheaper ‘mini’ projectors seem to use LCD’s but I guess they’d still have the UV filter on :frowning: Anything DLP seems to cost more - There’s the possibility of going used but it would make my work difficult to replicate!

The Droplit works with a $350 dlp projector which is not that bad at all. You need the DLP for the UV source I think. LEDs just don’t put out that much UV.

@Ben_Delarre
The iBox nano is $220 all in, which is what I would like to beat! I have a lot of parts here steppers/drivers/mechanical so could hopefully build it mostly for free.
I’ve been reading about modiying a used DLP projector with a UV LED, but would prefer to not use that route if possible.

You might try a high def led screen and modify it with an array of UV LEDs for backlight. But you might find its just not cost effective.

@Ben_Delarre I think the problem is LED screens have UV filters on them and are possibly damaged by UV!
