It's pretty simple, quick, and gives a decent result. What's not to like?
The hard part is having a 3D resin printer, but anyway.
As usual, show us how much better yours is.

Subject: Re: [homebrewpcbs] Exposing PCBs with a resin 3D printer
I don't see the point of that.
UV lamps are cheap adn so are printer transparencies.
My cheap inkjet can do 4800x2400DPI and good photoresist is cheap.
Compared to that, 3D printer is very crappy option.
I was thinking more along the lines of reworking something like Epson's
cheap A3+ Workforce WF-77xx printer or multifunction into printing directly
on PCB panel.
For me, that would be a meaningful change.
Pritner is GREAT in general, cheap and above all, great for exactly this
purpose.

There are a number of similar YouTube videos of this. I'm currently
experimenting with doing the same thing, but in a different way. I
bought a 9.7 inch 2K lcd with an HDMI board that I can use as a second
monitor. I going to remove the backlight and replace it with a UV
source. Print Eagle to a file then display the file on the lcd and use
it to expose the board. This should allow a lot more flexibility from
a software point of view. Also, the lcd on a resin printer has a
(relatively) thick piece of glass on the front to protect the screen
that could cause some refraction problems. Hopefully I'll get to try
this in the next week or so.
