Any question, feel free to contact us. We carry most parts for DIY project and turnkey machines as well. Both metal or non-metal are available for demo. Our price are competitive and our customer services are in top notch! No need to worry FDA or US Custom troublesome by buying direct from China because we shipped our machine from California. We inspected and fine tuned our machine before letting it go. Even our price may seems a little big higher but worth for trouble free and tech support.
Either give us a call or go to our website and I'm sure one of the machine will fit you right. Or, built one yourself to learn laser better.
