What’s a good solution for something cheap and flat I can put on my bed to go UNDER whatever I’m lasering? I mostly have wood products, but they burn. I’d like something easy to manipulate (i.e. store 😉 and about a couple feet on a side. Is there something magic that will just “take” a laser beam without harm? Maybe a thin aluminum veneer on some heatproof foam? (obviously, this is for cutting - paper so far, but I imagine thin wood and cardboard in the future. Not a problem for engraving, which doesn’t cut through) ---

Boom! > [@Vacuum honeycomb table for laser cutting](https://forum.avidcnc.com/t/vacuum-honeycomb-table-for-laser-cutting/1617/6): > > Good. Mine is aluminum. It stands up to the laser fine, but you have to be super careful not to drop or drag stuff across the top because its so thin it damages very easily. ---

I read that thread, honestly 😉 I was hoping to avoid honeycomb as it’s kinda expensive, and 2x3 feet is still small for me - I can cut up to 4x10 sheets of paper. Plus I think my laser has a longer focal length - I’ve burned wood many inches away from it by accident. I’d rather this laser-proof bed absorb the laser rather than let it fly past. ---

They make bigger honeycomb panels now, but 4x10 is huge, I haven’t seen them over about 4x4. Most people line the bottom with a stainless steel sheet now to handle the higher power and longer focal lengths. ---

My other attempt was to use gypsum wallboard (sheetrock) but for the paper coating ☹ ---

Could you do something similar to a plasma water table? ---

I don’t think so, as I also do regular wood milling, so this has to go on top of my regular wooden bed. ---

Oh I didn’t mean with the water but just making something that has the slats like a water table. Maybe you could make those out of thin pieces of wood and make it removable ---

I use the seklema mat. It’s like a self healing, sticky mat we use for trophy plate material in the awards shop. Keeps stuff in place. It has like an acrylic core so if you put a ton of power into the cut then you can cut through the mat, but you really have to put way more than you should.
