Won't work as well but might be OK, depending on the use.

Do what I did.

Go see your local Air conditioning wholesaler and buy an aluminium return air grill.

Works fine, and way cheaper that honeycomb grill.

Is this the sort of grille you're talking about?

I've thought about that, or the lattice for fluorescent lights.  I've been using expanded steel, and I find the contact patch is too large, and I'm not getting clean cuts.

You could try some auto mesh, like this:

I've bought some to try, and it does ok.

I'm currently in the process of making a vacuum bed with a finer stainless steel mesh and I'll let you know how that goes when it's finally built.

Hey Marcus,

Yep there the ones I'm talking about.
The one I got had a removable core so I don't have the aluminium angle surround getting in the way.

600mm x 500mm cost me AUD 60, not sure what the prices are like in the rest of the world.

12"  x 12" in the UK  about 16 on e bay.  (A$32?)  Larger types of course more expensive.

Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

SAFETY -  IS NO ACCIDENT

Hmm...so thin galvanized sheet of metal is not good option for cutting? Because that is what i plan to use. Havent run the laser yet. I will when i finish safety enclosure with acrylic laser filter etc...safety first!
