The present invention relates to an additive manufacturing system for powdery starting material which comprises electron beam guns as irradiation units. The system comprises an improved shielding against ionizing radiation, in particular x-rays. By use of the additive manufacturing system according to the invention a compact an lightweight shielding of the construction area is achieved.

The present invention relates to a doctor blade unit for an additive manufacturing system having a pulverous starting material. By means of the doctor blade unit according to the invention, improved linearity of the doctor blade and parallelism with respect to the build plane are achieved. The doctor blade is suspended on a crossmember by means of adjustable fastening elements, and the crossmember in turn is fastened, on one side by means of a fixed bearing and on the other side by means of a floating bearing, to a guide support.

A method and a device for producing ingots from metal or metal alloy. The method and the device are suitable for producing ingots from nickel, titanium, vanadium, niobium, tantalum, zirconium, hafnium, or alloys thereof and alloys of the metals in continuous casting methods. The device has an ingot chamber, which is suitable for receiving multiple cast ingots and for allowing the ingots to cool in the ingot chamber. For this purpose, the ingots are arranged in the ingot chamber in a horizontally movable manner on ingot tube section.
