Additive manufacturing (AM) techniques such as laser powder bed fusion (LPBF) and directed energy deposition (DED) are viable methods to produce large-size bulk metallic Glass (BMG) components. Even though BMGs with low glass forming abilities (GFA) can potentially be manufactured via AM, the resultant build undergoes partial devitrification, structural relaxation, cracking, or picks up oxygen (O). O pick-up is a serious issue for AM fabricated BMGs as it causes embrittlement and affects its potential use as a structural material. Here, a detailed review of the O pick-up in BMGs during AM fabrication is provided. The effect of O on the propensity of crystal nuclei formation and the glass forming ability of BMGs is critically discussed. Thereafter, the effect of on the mechanical properties of BMGs, and how it affects its structural performance are reviewed. Above a certain threshold, which could be composition-specific, O improves the strength of the BMG but diminishes its fracture, fatigue, and plasticity. These discussions will lead to the formulation of some future directions of research in AM fabrication of BMGs that have both scientific and technological relevance.

激光粉末床融合 (LPBF) 和定向能量沉积 (DED) 等增材制造 (AM) 技术是生产大尺寸块状金属玻璃 (BMG) 组件的可行方法。尽管具有低玻璃形成能力 (GFA) 的 BMG 可以通过 AM 制造，但最终的结构会经历部分失透、结构松弛、开裂或吸氧 (O)。O 拾取对于 AM 制造的 BMG 来说是一个严重的问题，因为它会导致脆化并影响其作为结构材料的潜在用途。在这里，提供了在 AM 制造过程中 BMG 中 O 拾取的详细回顾。批判性地讨论了 O 对 BMG 晶核形成倾向和玻璃形成能力的影响。此后，对 BMG 机械性能的影响，以及它如何影响其结构性能进行了审查。超过某个阈值（可能是特定于成分的），O 会提高 BMG 的强度，但会降低其断裂、疲劳和塑性。这些讨论将导致形成具有科学和技术相关性的 BMG 增材制造的一些未来研究方向。
