[Swansea Hackspace] Laser cutting plywood

[Aled]

I need to cut some shapes out for a kids party, I need to do a bunch the same do I thought the laser cutter would be the easiest way to do it. Does anyone know vwhat thickness of ply the laser cutter can cut cleanly? (3mm should be enough) and does it need void free birch ply or will any old plywood do?
Also can it engrave and cut in one operation?
Cheers.
