Hi all, is there a chart around for 365-405nm LED power cure times for various resins?
I'd like to know how fast I can print drop-by-drop. (ie: milliseconds?)

thanks

... this is different for every resin, used UV-LED's/-lasers types and optical/mechanical setup ... so don't await complete data charts ...

You seem to be pretty experienced, do you have any data for any setup/resin?

I heard the Epson piezo print heads have orifices that may be too small, preheating the resins may allow us to use them - thoughts?

... seems to be something between 1 to 15 seconds for unmodified DLP-beamers - [spotamaterials.com]

With my high power 9W@405nm-LED's this is much shorter, but too depends on the specific resin composition ...
