hi drago,

what happened with the film you were developing?

also, your curing time is subtantialy lower compared to the new chinese printer sold in aliexpress. i suppose you are using ftd resin, more than anything to compare results with hp. can you post lcd panel and led details?

I sold the rights to the membrane of another company
For the printer I use 1280x800 7 inches LCD and four kinds of LEDs with different power and different wavelength. I'm still not sure if this is the right combination because there are a problems if I use 100% power. The resin is cured the entire of the bottom.

Very nice nice build!
I'm all into Daylight printers (http://www.kvistholm.se/Daylight-Resin-Printer)

Would you mind sharing the VAT-construction (STL / .step)?
And where did you get the LED Matrix, if ebay, could you provide a link?

Hi,

How long was the curing time for 1 layer using the original backlight?

It did not work with the original background light. Or I did not have patience.
