I've got a couple of ideas for projects/ products in mind, but they call for learning to sand blast. It sounds like there are several people in the engraving business that include sandblasting in their business. My question is, what is used for sandblast resist (that can be cut with the laser) and where can I find it? I'm looking to do light blasting on glass, ceramics, metal and wood.
I'm hoping to get away with a micro pen blaster, so I don't have to drop too much money into something that may not work for me. I'd love to hear any comments, ideas and or opinions. Thanks.
