Good to jump into this new tech in more than one way... but I'm drooling for one of these things myself, no doubt it will go the way of the personal computer, home printer, etc... in other words, you want to get in now because it will be huge
I agree in that exone printer is not going to copied by chinese. They have buyers waiting at million per printer or lease at 100, 000 per month. No other 3d printer can make that claim today. There printers are being copied by chinese as we speak and will be selling on ebay for half of ddd or syss cost. With that makerbot is currently dominating the consumer 3d printer market and opening stores all over. Exone is risky but they embedding themselves with the bigest buyers more than any 3d company. Ddd fad will be played out ultimately by the chinese it is a predicted reality.
Excuse my typos, I am on a tablet. The exciting part is xone has no earnings and still up on ipo 50%. I look forward to price with actual earnings. Will be interesting to see if it takes off like ddd did.
