3D printing technologies in space

3D printing in space involves creating objects layer-by-layer using specialized printers aboard spacecraft or stations. This technology allows astronauts to produce tools, spare parts, or equipment on-demand, reducing the need to carry extensive supplies from Earth. Space 3D printers often work with materials like plastics or metals that can be melted and solidified precisely. This capability enhances mission autonomy, decreases costs, and supports long-term exploration by enabling repairs and new component fabrication directly in space, ultimately helping to establish sustainable human presence beyond Earth.
