What is 3D Printing and How Does it Work in Space?
Understanding 3D Printing
3D printing is a manufacturing process of creating three-dimensional objects from digital files. It involves building up layers of material, such as plastic, metal or ceramic, to create a physical object. This process uses additive technology where the materials are added layer by layer until the final product is complete.
How 3D Printing Works in Space
The use of 3D printing in space habitats has revolutionized space exploration through its ability to manufacture objects on-demand using locally sourced materials. The technology works by melting plastic or metal filaments into thin layers that are then deposited on top of each other to create a three-dimensional object.
