The article discusses how humanity's future pioneers in space will have to adapt similarly to historical settlers. They will rely heavily on 3D printers to create necessary tools, structures, and habitats. Unlike past adventurers who could utilize local resources readily, astronauts will face extraordinary challenges in environments where basic needs, such as breathable air, are non-existent. The article highlights the importance of 'additive manufacturing' technology, which already shows promise on the International Space Station through the production of essential parts and tools.
Instead of axes and plows, however, today's space pioneers will bring 3D printers. These machines are crucial for tools, structures, and habitats to survive in a hostile environment.
3D printing is often called 'additive manufacturing,' because you keep adding material to make the part, rather than removing it, as done in conventional machining.
