    Yes, that's essentially the process. It uses a YAG laser which is a different type of laser to the CO2 lasers schools are familiar with.
    The machines were selling in excess £100K some years ago with an anticipated maintenance cost of 10% per annum, although I had heard of a Chinese machine at 1/4 of the cost and a finger in the air at the maintenance cost.
    I'm all for the advancement of technolgy, but if putting an image inside a block of acrylic iat all this cost s all it can do is a bit of a waste of time, unless you accept that the frivolous use of the technology pays for the development of more productive uses for it in the future.
