Additive Manufacturing in Microgravity — 3D Printing in Space

Additive manufacturing in microgravity could transform space exploration by moving the factory off Earth and into the void — eliminating the enormous cost of cargo launches. Isaac Arthur explores how 3D printing in freefall works around the physics challenges of low gravity, how regolith from moons and asteroids can serve as raw material, and why this technology is the key to constructing shipyards, mega-telescopes, and orbital infrastructure at scales no rocket was ever designed to carry. From the messy middle of low-gravity printing to manufacturing at civilisation-defining scales, this episode of Science and Futurism with Isaac Arthur (SFIA) breaks down why additive manufacturing isn't science fiction — it's the most practical path to building humanity's future in space.
