I just reviewed the Printrbot simple, a $350 3D printer that is, well, simple…

Until recently, the idea of a 3D printer that costs $350 producing anything decent would have been laughable. Now it is a reality, though you’ll have to live with compromises — such as the lack of a display or controls on the device, the small build area, the limitation of only one printing material, and the device’s tendency to jam.
