| Popis: | In the present paper, recent progress regarding additive manufacturing (AM) of pure tungsten (W) by means of laser powder bed fusion (LPBF) is discussed. In this context, several aspects are highlighted: The influence of the raw powder material characteristics on the resulting W part quality is briefly discussed, examples for complexly shaped additively manufactured W lattice structure samples are shown, the application of an additively manufactured W structure as preform for a tungsten-copper (W-Cu) composite is illustrated and thermal shock experiments on additively manufactured bulk W samples with the electron beam facility JUDITH 2 are described. The latter demonstrates that W material consolidated by means of LPBF is capable of surviving intense thermal shock loads. This is an encouraging result indicating that the thermal performance and stability of W fabricated by means of LPBF is comparable to that of conventionally fabricated W which in turn implies that the further investigation of additively manufactured W as candidate material with regard to applications in highly loaded plasma-facing components (PFCs) of future magnetic confinement thermonuclear fusion devices can be considered worthwhile. |
