A lamp, phone charger, toothbrush charger, holstered handgun, flashlight, and some hair ties. I'll put my glasses and watch on top too before going to sleep.

Oh, and a lot of dust.

PCB solder mask making using UV resin

It appears to me that UV resin, used for SLA printers should be quite convenient for making PCBs with a laser etcher. You can spread a thin layer of resin on the board and quickly expose it using a laser engraver. It should be most convenient for silkscreen layers that are otherwise difficult to apply....

Honestly, interesting thought.

My first concern is fidelity - you can only get as detailed as the diameter of your laser, which I imagine is pretty big relative to the tiny features on PCBs. A 10 mil diameter sounds pretty good for a home job to me.

How well does cured resin hold up to copper etchants? I would assume pretty well.

What benefit does this have over other methods, such as transferring a laser print on glossy paper to a blank PCB? The resin/laser method sounds very similar, but more automated and essentially the same, minus the transfer step.

Now I want to try this haha.
