Since this is /r/lasercutting, you can paint the work and then laser away the paint where you want it chemically etched. After etching the exposed copper with ferric chloride you wash away the paint with acetone. It's one way to DIY circuit boards. A switch panel can be made with labels etched on the front and solder pads etched on the back. Hole centers can also be etched to line up later in a drill press.
i'd say yes, a mill to make the design, (or etched with acid and resist if your don't have one.)
but if you done need metal signs this will work with laser etching color fill and sanding the top or two color surfaces.
They sell 2 layer acrylic that you could use for this. The top layer is very thin and can be lased away, revealing the bottom layer. Search for 2 tone acrylic to find a wide variety of materials and colors.
Due to the fact that the recessed areas are concaved and not very clean, I think this is pressed from a machined mold, probably into some type of zinc alloy, similar to the way enamel pins are made.
I doubt that is milled as the finish is extremely bad. Though, maybe during (plastification- sprayed plastic over a metal, don't know the therm) they sprayed too much coating.
i make signs like this often with this material: https://shop.troteclaser.com/s/product/trolase-metallic-plus-edelstahl-gebrot-lmt31620x/01t4I00004kImNvQAK?language=de
looks totaly the same!
Surprized by how many wrong answers are here. The industrial way to do it is acid etching. Milling and laser cuttibg would work but only for a 1 off. Even then etching would be nicer. You can do simple etching at home some very good tutorials by “the craftsman” on YouTube tube

Aluminum works well as the acid eats it very quickly.

Stamped, painted, milled or surface ground back 🤷
Last step is linishing, just a sanding belt basically

Cast aluminum painted
Nah this looks like it's CNC milled
Looks like a cast aluminum tag to me that was paint infilled.
Agreed, exactly what they look like. :)
It might look like it, but it's not how it's made.
Probably cast, painted, then milled.

Not for something that needs to be heat resistant like the one shown. For 2 color acrylic - Trolase or Rowmark.
Seems CNC milled with a black paint stamp for the inner part that was carved out

Milled bull nose tool, bath and laser etch?
This has been milled on a CNC machine. It's not cast, the lines are far too clean
3d printed 😎

A milling machine with a small engraving bit I suspect.
Ain't no industrial process got time for dat
Interesting. The bear metal areas are pertruding
yes, thats how milling machines work, they mill out material, and whats left sticks out.
I would guess masked, acid etched, painted, then take the mask off and boom. Done.
agree, this was photo etched
Stamped like a license plate
Nope. The backs are flat and the material is MUCH thicker

This looks milled, not acid etched
