[0002] 3D printing, also known as additive manufacturing, is a technology that creates three-dimensional objects by adding materials layer by layer. Unlike traditional subtractive manufacturing, 3D printing can quickly transform digital models into physical objects by precisely controlling the order in which materials are added. 3D printing filament connectors usually refer to components used to connect filaments to the printer during the 3D printing process. The filaments are provided in the form of filaments and are fed into the printer nozzles through connectors or feeding systems.
