And here is the result :

Business card (flat)Business card (engraving)

I used the correct speed and laser power to cut where needed and a very, very low power to engrave the text.
The resulting card can be folded to simulate my logo in a "3D" fashion while being able to stand by itself.

Business card (folded)

This is my first prototype and for the next step (mass production) I plan to print the text on paper first (with a regular inkjet or laser printer) and to only use the laser cut machine for cutting them out (no engrave).

I don't know about you but I really like it !
