Filaments
Filament is the material used in 3D printing to create three-dimensional objects. It is typically a long, flexible spool of material that is fed into a 3D printer's extruder, where it is heated and melted to form layers that gradually build up the object. The choice of filament is crucial to the success of 3D printing because it impacts the print quality, strength, flexibility, and final appearance of the printed model.
