Yes cannot see why it would not work on a pi3 the hardware is extremly similar. I did a reinstall of nanodlp today to verify my settings in the config file and here they are. I am in Canada and already owned a pi2 b+ and i am at about $120 canadian for an ipad screen and the controller with a ramps board and arduino. I figure to build a nice switching powersupply for the 5v and 12v and the stepper i will be about $150 for electronics. The hardware ill be about another $100. Its the resin that is expensive.

Hi all,

Very interested in this thread and will be keeping an eye on, well done guys/gals for the progress so far as it made for a very interesting read.

For what its worth, I ordered a Retina Screen over the weekend before seeing this thread and aim to have a close look at, have a fair selection of Tech / Equip here.
Screen Part Number for the iPad3 LCD I purchased is LP097QX1.

This all is looking very inspiring! I've been researching a lot lately on how to get in SLA printing cheap and build my own. I will ben following this thread closely and hope to add some info as well!

 

That is the exact Video Adapter I was looking at buying for it, still have the option to run a board off here but would mean getting my PCB equip out, I have functional schematics to use it with a DisplayPort BUT would definitely save messing around and as you guessed, would also be wanting to run it from a Pi on NanoDLP.

 

It would be a very interesting concept if the front polariser could be removed allowing the colour filters to be accessed and dissolved/peeled/etched away etc as the price, size and pixel size of the panel would make for some interesting prints.
I have some older LCD's which I would be willing to take apart for science and try the above on.

 

Scrap that idea, have disassembled a couple of old screens and the thing they share in common is the colour filter is sandwiched between the 2x glass layers, no physical access to it.
Only viable possibility is to use a blue laser of moderate power to fade the non blue pixels? did see on another thread about bleaching colour with UV but after reading this thread, it would appear that other layers will block UV anyway.

 

Totally agree with the mono screens.
Lasers wise I have quite a few, Co2 would be of no use for stripping the colour filter as the glass would be opaque to that wavelength and destroyed, 405nM/455 would be another option, the blue filters will surely be quite transmissive to it whilst the other colours should in fact be quickly faded by the intensity, is something I will put some more thought in to.
Main screens I have to play around with (old pile of unused panels) are the LQ043 (PSP series), granted they would be nowhere near ideal pixel density but for something to play with, certainly don't fancy wrecking a few brand new Retina Screens as they make excellent external external screens.

 

There are a few Barco medical displays on eBay for relatively cheap.
Barco BarcoView Model: MFGD-3420 Grayscale Medical 21" LCD Display Monitor | eBay
Can't afford it at the moment but this is the cheapest I've been able to find.

 

I agree. Only 122ppi Not really a winner on the x/y resolution front

@evilc66 any updates on your experiences (luck with daylight resins, any foray in to UV etc...')???

 

Anyone have idea of the LCD printer which sold at aliexpress ?

 

Not sure why i could not attach a link .

www.aliexpress.com

 

You could search "SLA 3d printer" there is some results .

 

Recognise that avitar, still got your reef tanks

 

I lost my tank after a heater broke and tripped the RCD, I do miss it but in the end I was spending hours testing water, working out dosing all the fun of an sps the tank.

 

I have my bottle of photocentric Amber, low shrinkage, hard, just sitting here awaiting my next move as well.

I have not set myself on a specific LCD. Most should work with Daylight resins. I've been considering an 8" model I found with matching LVDS controller.

Many people seem farther along than I am and I'm still hoping that someone figures out a way to use the LCD panels for both UV and daylight (or at lease 405nm I suppose).

My homebrew DLP setup seems to work well at 365nm (or so I guess) but I find the projectors to be bulky, complicated and overall not friendly.

 

Hi friends,

Im new here, really fantastic all work i found on this forum, there are many people here that are working very hard..

I've been dreaming of manufacture a large format printer, I do not have as much knowledge as you do in this.... try to understand all these concepts and learn everything I can....

My dreaming will be have a 40-50" printer, yes i see the large format f¡rom photocentics, but think uv will better so will work faster....

I will try to learn as much as possible of you and see if at the end you find a real solution that allows the conversion of a 4K screen for this purpose

Thanks for all

nando
