Yes. Nothing left except gas and smoke. Some "problematic" materials can be cut if they're really thin. An eight of an inch is too much. > There is no charring on the cut. Other materials like wood and paper will char. This is why air assist is essential. It also keeps the soot away from the lens protector. Just a couple of years ago that was typically a modification you had to do yourself, usually reinventing the wheel in the process. Now every manufacturer has a big aquarium pump hooked to a nozzle on the business end of the laser module. Note that light charring can sometime be brushed off or removed with a "magic" eraser. > Maybe Titanium Dioxide is another wavelength thing ?
