Agnirva Space Premier League - Expedition #30869: FREEDOM in Orbit: Testing Next-Gen Metal Forming Techniques in Space

What happens when you try to form metal without gravity helping you? The FREEDOM experiment, developed by Nakashimada Engineering Works and Tohoku University, explores that question in orbit.

During Expeditions 49/50 aboard the ISS, researchers tested a unique high-velocity forming process for metals under microgravity conditions. This technique—used on Earth for shaping high-strength materials—relies on rapid energy transfer instead of traditional stamping or pressing.

In space, without gravity and with reduced structural stress, researchers observed how metal deforms, flows, and cools differently. Cameras and sensors recorded the experiments inside a specialized chamber, revealing how microgravity impacts material ductility, residual stress, and forming precision.

The FREEDOM results provide critical insights for in-space manufacturing, especially for future missions needing on-demand fabrication or repair capabilities. It also benefits Earth industries that deal with high-strength, lightweight materials like aerospace, automotive, and defense sectors.

By understanding metal behavior without gravity’s interference, engineers can refine forming methods, reduce waste, and design new materials with greater precision.
