Additive manufacturing of concrete elements

Additive manufacturing has evolved in recent years from its origins of rapid prototyping to a future-oriented production technology. Fully functional construction elements are today already being manufactured for direct application in many areas. The advantages of additive manufacturing lie in the elimination of complex formwork construction and in the individual adaptation of the construction elements: which promises for the future the combination of economic advantages and efficient materials utilization.

A dynamic development in recent years has also become apparent in the development of...
