Well, as you can see from the latest video. I have a UV laser scanner built, but before mechanisi
ng it so it swings across a
glass plate , I tried a few other experimen
ts with the resins I intend to use. They seemed to work great, but I see they seem to
work better with UV LED's.. so.. now Im waiting for a 7" LCD monitor and some 30 candlepow
er UV LED's I ordered in to see
if I can modifiy a small video monitor to give off the image in UV.. I like this idea because if it works it can be done with no mechanics
at all for the image. I suppose in the end I coulda just gotten a projector like you see others doing, but to me the whole project
has been about learnign the various ways to do it before settling on the cheapest and best working. If the monitor works it
means an entire printer could be done for about 200$ or so. Ive taken apart a few LCD monitors and it seem it shoudl work if
I just remove the lamps and put in some UV bright leds'. The LCD "should" allow enough attenuati
on of the light when off
so that on segments only will harden the resin. Ive gotten my resin down to where about 20 seconds of UV hardens a small pot
of it, and I can draw a letter in the resin and pick it up after a minute or so. The resin is about 15$ a litre or so to make, much
better than the $800.00 a litre Ive been seeing elsewhere
. A litre woudl make a whole lot of stuff.
So I shoudl have my monitor in a couple weeks and Ill post how that conversio
n comes out. I must say it has been fun playing
wih all the technolog
ies to see how they work. Ive gone from Inkjet to Laser printer now to UV video monitor..
but its all a great
learning experienc
e. In the end I hope to just have the cheapest way of doing it all. (not that Im that cheap..bu
t I figure
if its cheap enough everyone will try to build one
)
