Hi, Has anyone tried using a low power lasers from cd/dvd or blue ray burner drives? I expect the accuracy could be quite good. A blue ray laser should be capable of exposing photoresist very well, but are quite expensive. I imagine this could also be used directly on a board coated in toner? Im not sure about red dvd lasers - it would depend if photo resist is also sensitive to heat? Most of these lasers are ~200-300mW, that should be able to melt plastics if focused, although I have not managed to get my laser to burn at 150mW yet. However there are many youtube videos showing these lasers used for cnc engraving plastics. thanks
