flag China successfully tested metal 3D printing in space, marking a major step in in-orbit manufacturing.

flag China successfully conducted its first metal 3D printing experiment in space using a retrievable payload launched aboard the Lihong-1 Y1 suborbital vehicle from Jiuquan on January 12, 2026. flag Reaching about 120 kilometers altitude, the payload autonomously fabricated metal components in microgravity, overcoming challenges in material transport, control systems, and coordination. flag The capsule returned safely, enabling scientists to analyze melt pool dynamics and part quality. flag This milestone advances China’s in-orbit manufacturing from ground testing to real-space validation. flag The reusable Lihong-1 Y1 also carried rose seeds and is being upgraded for crewed missions and space tourism.
