Build Your Own SLA/SLS

I think the polarizers are the UV filters, its part of their function Yes, I think you are right, but also not all polarizers are equal, maybe some allow more UV than others, depending on the base material perhaps. I have recently stripped down an ancient astrobeam lcd projector, and the lcd panel ...

Good news what did you do different?. Reading the info, it seems that the polarizers, or at least the second one, allow us to see the image, as without it we see nothing, I have not yet got my head around wether it would cure resin without the second polarizer, ie, is an image formed but not visable...

You could test it on a spot of resin spread onto glass, Dentists use uv resin for fillings, I have some its thick paste, is it white light or uv, have you looked inside at the light source?, if its suitable, you could make an adaptor to the light gate, so you can revert back to the bulb if needed.

I bought the light cable for about £7/mtr, its 6mm with a sheath diameter of about 10mm, the ends need polishing with wet and dry, then finish with brass polish, the poor phone image shows the sheath cut to allow insertion into the adaptor. lightcable.jpg The box has one led initialy, but has holes ...

You are very welcome Nick, LCD's are plentifull and cheap from old monitors, so please keep posting your work, I think one other
member is working with lcd.

Yes we are lucky to get such a nice piece of software, it means we do not have to mess around to get our printers running

Very nice, the Z stage looks good, wish I had that much space in my workshop. how did you do the supports for the iron man? they look angled.

Nice, that platform holder looks the business, the exposure looks to be about seven seconds, is that from trial and error for the resin,
Would you or someone consider writing a simple guide, or steps to ascertain exposure settings???.

Anyway thanks for letting us see your work.

Good work, thanks for shareing.

my sympathies with the toshiba, I have one, it took ages just to get to the inards, I decided not to use it for sla, but a structured light scanner instead. old HP6120 type dlp are a dream to work on, bigger, older, and maybe lower resolution, but excellent for hacking, I bought 3 at £5 each plus sh...
