Abstract
The production of three-dimensional bodies is performed by selective solidification, wherein surface impurities on the layers to be produced, which may occur during the production process using “powder shuttle” technology, are significantly reduced or eliminated. In this manner the production process is more efficient, produces a higher grade product and is more economical to implement.
