I really liked the Ponoko website and just wanted to share some ideas with the community and hopefully there are going to be some other comments :).
I believe that 3dp is going to revolutionize a lot of different business models. One of the most interesting and fun to think about (at least to me) is Lego. I believe that in the future these guys are going to sell 3dp with LEGO brand on it. Basically all you need is to download your model and here you are with a new set that you printed at home. Lego printers are going to be secure. In other words you can only use their model files on that kind of printers. Lego obviously will supply their cartridges with the plastic of "very high quality" and develop models. What do you think? Does that sound like a new business strategy?
