DEVICE AND METHOD FOR MANUFACTURING COMPONENTS TAKING INTO ACCOUNT THE INLINE DETERMINED POURABILITY CHARACTERISTICS OF A POWDER

Abstract: the present invention relates to a device for manufacturing components layer by layer by locally selective solidification of material powder in a process area by electromagnetic radiation or particle radiation. the device comprises a powder supply for supplying powder p to the process area. the powder supply comprises a powder conduit which is connected to a funnel section , and at least one controllable shut-off valve v, v which is arranged downstream of the funnel section in a powder flow direction r. the device enables inline determination of the pourability characteristics of the powder that is actually used.
