Just a day dream.
Going to the NYC Maker Faire Sunday and I'll get a chance to talk to lots of people. There's a new printer designed by some guys from MIT, mostly for themselves. Four times the resolution of the Makerbot (that's 64 squirts of the nozzle for each Makerbot squirt) (4 times 4 times 4) and it uses laser fusing.
It's volume is something like 4.9 by 4.9 by 6 or so. Very nice finish on what it makes but too small for a lot of things.
Check out Tinkerine Studio booth when you are there. They are some of the people from my local 3d Printer club. They are showcasing there ditto printer. I want to replace my Huxley with one of these soon. Great Printer and its not closed source like the new MakerBot. Also I believe its under 1000.
Here is a link to there website
Enjoy MakerFaire. One day I need to go to New York one.
