中国在空间成功地生产了3D印刷金属,标志着在轨道制造方面迈出了一大步。 China successfully 3D printed metal in space, marking a major step in in-orbit manufacturing.

中国成功地完成了其在空间的第一次金属3D印刷实验,标志着轨道内制造业的飞跃。 China has successfully completed its first metal 3D printing experiment in space, marking a major leap in in-orbit manufacturing. 这次试验由中国科学院的可回收有效载荷进行,1月12日从久泉发射的利洪-1Y1亚轨道飞行器上发射。 The test, conducted by a retrievable payload from the Chinese Academy of Sciences, launched aboard the Lihong-1 Y1 suborbital vehicle from Jiuquan on January 12. 在达到Kármán线以上约120公里的高度后,载荷在微重力中自动制造的金属部件,克服了物质运输和闭路控制等重大挑战。 After reaching about 120 kilometers altitude—above the Kármán line—the payload autonomously fabricated metal components in microgravity, overcoming key challenges like material transport and closed-loop control. 舱体通过降落伞安全返回，使科学家能够分析熔池动力学、材料行为和零件质量。 The capsule returned safely via parachute, enabling scientists to analyze melt pool dynamics, material behavior, and part quality. 这一里程碑将中国的空间金属印刷从地面研究过渡到空间工程验证。 This milestone transitions China’s space metal printing from ground research to in-space engineering validation. 重用利洪-1Y1还携带了用于农业研究的玫瑰种子,并正在对机组任务和带有生命支持和逃生系统的空间旅游进行升级改造。 The reusable Lihong-1 Y1 also carried rose seeds for agricultural research and is being upgraded for crewed missions and space tourism with life-support and escape systems.
