Everyone is saying buy a full HD projector for the SLA printer. I understand, but my wallet doesn't just yet. Correct me if I'm wrong, but if Jack purchases a 1080p (1920 x 1080 pixels) and he focuses it on a large vat, let's say like the 280mm by 200mm flex vat of the mUVe printer, then the ultimate resolution on the wide measure is 280mm/1920, which is .145mm per pixel.
And I just purchased a SVGA DLP projector off Craigslist for $40. It has a native resolution of 800 X 600 pixels. If I focus it down on a vat that for an 80mm by 60mm size, then my print resolution in this smaller area would be .1mm per pixel. Higher resolution than Jacks printer, but it cannot print a large object like his machine.
Is this correct? Is anyone aware of any tests with resins that define what the ultimate resolution capacity is?
This is the place to discuss DLP projectors, UV Lasers, Galvanometers, LCD screens and similar display devices. Also discussed are optics in general.
