Delta robot

The idea of delta robot fascinated me from the beginning. However this robots are widely used in the industry and also for 3d printing I find that their potential is still not fully used. For example lack of deltabots in larger scales... I was amazed by the simplicity of its construction which could only by using three servos or motors easily reach any point in space. 

I find it suitable for extreme environment for multiple reasons: the construction could be relative light and they could be easily decomposed or folded and then rebuild again in other place. The movement of the arms is not based on Cartesian grid coordinates like other conventional 3d printers but rather on circular or spherical movement, which I find more suitable for anamorphic landscape of dunes.

There are at least two different ways how can delta 3d printer work. One of them is the traditional way where the robot prints layers of glue or any other binding material on top of each other. For printing in sand it means that there need to be  layer of sand add after each layer of glue.  

Another way would be printing directly in 3d space by using pile of sans as the base for printing and then add the glue on surface
