Both machines working together will enable me to get some ideas off the ground. Both processes have advantages and disadvantages. Used to work for a company that did both... BIG honking SLI and Sintering style machines as well as state of the art injection molding technology. we made some amazing stuff by harnessing both processes, and CNC milling.
That's my background. Plastics. Materials specifically. Eventually once I see enough consumer-oriented business for these machines ("one in every home") I intend to rock the world with material innovations. Some folks are getting there now, but they are hackers and makers. In order to really kick things off, someone needs to build upon that groundwork.
In order to get to the point where there is one in every home... people need a reason to buy one. That's the main thrust of my efforts for the time being. I'll be detailing that in another thread once I get an answer from the admins.
