摘要

With advancements in manufacturing technology, the applications of materials with outstanding properties have been studied across various industries. From this perspective, the paper focuses on reviewing industrial applications via bulk metallic glasses (BMGs) having superior properties and additive manufacturing (AM) that can fabricate complex shapes. We investigate the history of bulk metallic glass (BMG) from initial development to recent industrial applications using AM in Sect. 1. In Sect. 2, we introduce seven groups of AM technologies according to standards. Among various AM technologies, AM technologies capable of three-dimensional complex shape deposition while maintaining the amorphous characteristics of BMG and industrial applications manufactured by AMs are introduced. In Sect. 3, the industrial application parts with potential for future production are proposed based on the characteristics of BMGs and AMs. In Sect. 4, the future directions of technologies to achieve higher and more diverse levels of industrial applications for BMG-AM are discussed in terms of six topics. We evaluate the printability and applicability of the unexplored Fe-based BMG, FeCrBSiC, using PBF technology. A maximum surface density of 86% and a Vickers hardness of 1010 HV with an amorphous structure are achieved at a laser power of 60 W and a scan speed of 1300 mm/s. In addition, lattice structures and hybrid structures are fabricated to demonstrate the potential of FeCrBSiC for diverse industrial applications through AM designs. This review provides guidance for future research and industrial applications of BMG-AM by outlining current progress, key challenges, and potential directions.
