▎ 摘　　要

NOVELTY - The device has a filament (10) for additive manufacturing, and filament that is filled with fillers (11), and a stationary sensor arrangement (20). The fillers are more than 1% by weight of fillers from the group comprising soot particles, graphene, carbon nanotubes or metal particles based on the total weight of filament. The filament with the fillers is guided along the sensor arrangement. The sensor arrangement is provided with a measuring coil (21) for measuring induction currents for induction measurement. The sensor arrangement is provided with an excitation coil (22) for the filament. The excitation coil supplied with an alternating current whose frequency is in the range of 25 kHz to 100 MHz. USE - Device for producing filament with device for detecting distribution of fillers within filament used in additive manufacturing of radar absorption component. ADVANTAGE - The distribution of fillers within the filament can be detected. The deviations in the distribution of the filaments can be identified and the quality of the filament can be monitored. The use of multiple frequencies for measurement leads to a larger amount of data for which a target/actual comparison can be carried out, so that the sensitivity of the measurement for quality assurance applications can be increased. DESCRIPTION OF DRAWING(S) - The drawings show the sectional views of the filament illustrating areas showing different distribution of fillers and sensor arrangement with measuring coil for measuring induction currents.
