“…Furthermore, the layer-wise built strategy and selective melting allow for local cooling rates largely to be decoupled from the actual part dimensions. Initially published by Pauly et al [7], investigating a Fe-based alloy, LPBF of various Zr-, Fe-, Al-, and Ti-based alloys have been reported in recent years [8][9][10][11][12][13][14][15]. One can conclude that adequate parameter selection may lead to sufficient cooling rates and hence amorphous solidification.…”

Laser powder bed fusion of bulk metallic glasses offers great potential to overcome the existing restrictions of the geometrical size and complexity of bulk metallic glasses in conventional manufacturing routes due to high cooling rates during laser powder bed fusion. Bulk metallic glasses exhibit extraordinary strength, paired with high elasticity. Yet insights into additive manufactured bulk metallic glasses, especially of complex structures, are limited. The present article investigates the mechanical behaviour of Zrbased bulk metallic glasses, fabricated into honeycomb structures through laser powder bed fusion, by performing three-point bending tests. The results reveal a significant increase in specific strength, quasi-plasticity, and high elastic elongation. These structures thus offer great potential for lightweight applications and compliant mechanisms.
