Tall. That's one way to describe the incredible Delta Tower 3D printer. It uses, obviously, the delta technique for rapidly and efficiently moving the single or dual extruders through each layer during printing.
The statistic you're looking for is this: it can print items up to 580mm tall, approximately twice that of the biggest conventional personal 3D printers. Even better, it can manage a resolution of up to 0.1mm.
One interesting feature is its ability to self-level. We observed the machine going through a leveling sequence that seemed to work quite well. It detects the tilt of the bed and simply adjusts the first layer appropriately.
While the Swiss-and-German built device is sold mainly in Europe it is currently available for purchase for €6000 (USD$8100).
