The Ultimate Nerdbait: How to Make Scannable QR Code Bar Code Street Art

Step 2: Making a CAD Model of the Stencil

I traced the QR Code into a CAD program.  It took me about one lunch break.  I also connected some of the corner pieces so they wouldn't be "knife edges".  The codes are pretty robust and forgiving to little doodads like that.

Maybe try a Rasterbator to print it.... such as http://homokaasu.org/rasterbator/ ...

Corel draw is another good option. Also, Solidworks has a trace function, but I haven't had much of a chance to try it out, and I don't think it would be available on the tutorial. Really the only thing that you need is some sort of vector graphics software because that is what the laser engraver needs since they cut vectors and engrave bitmaps.

Better yet just import it into Flash and vectorize it using the Trace Bitmap function. Then you could just go to a graphics shop and get a silkscreen made of it.
