How does 3D Printing work?
3D printing or additive manufacturing is a method that creates a three dimensional object from a digital file. This additive process works by laying down successive layers of material or filament until the object is created. Each layer can be seen as a thinly sliced cross-section of the object.
Filament! What is it??
Filaments used in 3D printing are thermoplastics which are plastics that melt when heated. They can be shaped and molded, and solidify when cooled. The filament is fed into a heating chamber in the printer's extruder assembly, where it is heated to its melting point and then extruded through a metal nozzle as the extruder assembly moves, tracing a path programmed into a 3D object file to create, layer by layer, the printed object. Although most 3D printers have a single extruder, there are some dual-extruder models that can print an object in different colors or with different filament types.
