Cutting Tin Foil!

Just discovered I can cut tin foil. Use a light spray of Cermark metal laser marking spray on the laser side. cut at full power, 500 speed. Leaves a black, clean edge. Renolds Wrap Heavy Duty Foil.

While interesting…personally I would consider using an expensive spray like Cermark as a waste of money and time. Are you making something with laser cut foil pieces?

I’m guessing it serves as a conduit for enough extra heat!

I needed to make a heat shield in an odd shape for a client. They pay my expenses, of course. And yes, the Cermark absorbed the energy and melted the foil. I think I wasted more spray clearing the nozzle than I did coating the foil.

I wonder if any sort of laser absorbent material would do the trick? I had success with foil backed cardstock, maybe the same principle?

I would think any black spray paint would work…

Yeah that’s a good thought. The nice thing about the cermark is that it washes away where you don’t laser. If you used paint (any color), you’d be left with painted foil, which may or may not be ok depending on your use. Hmm. Maybe a washable paint?

I wonder if may be as simple as a cardstock, foil sandwich? I’m not close to the laser or I’d try it.

Hmm maybe? I’d think you would want the laserable material in full contact with the foil, if there’s any gap it might cause it to fail. Glue would work, but you don’t want to wrestle with the foil after the cut.

The sandwich is a good idea, should give it a whirl .

I was thinking spray paint because that’s what I have in the shop.

however tempra paint being waterbased for kids should wash off completely.?

I would think so anyways. :slight_smile:

A quick 15 minute experiment told me it’s not that simple. I did get some scoring and holes in the foil but it wasn’t clean and simple.

I again cut some 0.010" aluminum foil dusted with Cermark at speed: 500, power: full and it worked great. My guess is that there is a chemical reaction with the Cermark that creates the permanent marking (the intended purpose) but also lots of heat.
