I got this new material in yesterday, and did some engrave tests and cuts! I really like the surface color of the material, with the contrast it gives, especially with the color of the engrave!! I mean, just look how DARK the engrave is!!! Practically completely black! This is due to the density of the material. Check out that carbon residue from wiping the side of the rosewood pin on my hand though. That is a sign that you reallllly don't have enough air pressure to cut this kind of material in this case XD(Black sides like that can also be caused by just too high power, or too low of speed.)

Since it is An Mdf board with a rosewood veneer, this means a couple different things. one, Those engraves can get black without disintegrating the material completely! Two, This material is TOUGH to cut. I spent about 20 minutes trying to figure out how to cut this 4mm mdf veneer without catching the material on fire, while still maintaining a completely clean cut through the material. I am barely able to cut this with a low power air assisted 11W diode laser. 

I have the equivalent of an aquarium air pump that I use for the air assist(Air assist cleans the cut out as the laser cuts the material, enabling the laser to cut deeper materials, while at the same time, preventing charring and burning.). This is a low power air assist, which means it only works up to a certain density/depth of material. Honestly, for cutting this material, you want a true air compressor capable of around 30 psi being pushed through the nozzle of your laser head.
