A friend of mine runs a "community technology centre" and is always looking for ideas. I casually mentioned 3D printers and he's really run with the concept and has ideas of printing bits for local RC clubs and making souvenirs and stuff (being aware of the timeframes and expense involved). Anyway, I haven't been keeping up with things in too much detail, but he wants some pointers as to which units he should be considering. Soooo.. what's the current state of things? Are there a couple of major players to choose between? Or is it still very much DIY? What would be a realistic budget for him to put to his club board?
