Agnirva Space Premier League - Expedition #30808: Building in Space: Exploring the Extrusion Process Aboard the ISS

What if we could manufacture materials in space just like we do on Earth? The 'Extrusion' experiment, led by Dr. Ariel Ekblaw from MIT, explores this fascinating possibility. Conducted during Expedition 68, the study investigates how materials behave when forced through a die—a process called extrusion—under microgravity.

Extrusion is used widely on Earth to shape materials like plastics and metals. In space, this process could be key for 3D printing structures, tools, or even habitats. But without gravity, the behavior of molten or semi-solid materials can change dramatically.

This experiment tests how materials flow, cool, and solidify during extrusion on the ISS. The data helps engineers design systems that could one day print infrastructure directly in space, reducing the need to launch everything from Earth.

Imagine astronauts printing tools on demand or building satellites and habitats in orbit. This could revolutionize space missions, making them more self-sufficient and flexible.

'Extrusion' not only advances manufacturing in space but also inspires students to think creatively about solving engineering problems beyond Earth. It’s a glimpse into a future where building in space isn’t science fiction—it’s reality.
