Good Grief, I just heard about a Kickstarter campaign for a sub-$300 3D printer called The Micro. One thing I really like about this unit -- in addition to the low price, of course -- is that it's designed to work right out of the box. All you have to so is plug the printer into your computer (it works with Windows, Macs, and Linux-based systems) and you're ready to rock and roll.
Another thing I really like is the fact that it has a sensor and feedback system built into the print head. This provides auto-leveling and auto-calibration, which means that the printer works every time you run it, even after thousands of hours of use. (By comparison, it took about 30 hours to calibrate and level my #$%^ 3D printer!)
The folks running this Kickstarter campaign really seem to know what they are doing, not the least that they've managed to raise more than $3,000,000 of their $50,000 goal. The thing is that there's less than a day to go on this campaign as I pen these words, so if you are interested in learning more, there's no time like right now!
