近日，我国完成了首次基于火箭平台实施太空金属增材制造返回式科学实验。本次实验，首次在太空微 重力下制造出完整金属构件。这标志着中国太空金属制造技术从"地面验证"阶段迈入"太空工程验证"新 阶段。这一突破将有力推动我国太空制造技术的发展，为未来航天器在轨快速制造与自主修复、深空探 测及地外基地建设奠定关键技术基础。 太空金属增材制造即太空金属3D打印，被视为未来航天任务的关键赋能技术。 在传统航天任务中大多采用的是"地造天用"的模式，即航天所需的设备零件由地面供给。这意味着航天 的设备零件在面临高运输成本的同时还受到了传统火箭发射尺寸的限制。试想一下，如果在太空航天任 务中出现零件损坏，从地球运输维修配件与物资，将耗费多少资金成本与物资成本？而此次技术突破， 实现了太空极端环境下低成本、低损耗的在轨维修作业，为商业航天降本增效拓宽路径，拓展发展边界 提供了全新可能。 近年来，中国在国家顶层战略中明确将太空金属3D打印列为关键发展领域，为其提供了坚实的政策与 项目支持。2025年11月，国家航天局设立商业航天司，商业航天领域迎来专职监管机构。同月国家航天 局印发了《国家航天局推进商业航天高质量安全发展行动计划(2 ...
