The Additive Manufacturing and 3D Printing Extrusion

Additive manufacturing, commonly known as 3D printing, builds objects by adding material layer by layer based on digital designs. Extrusion is a popular 3D printing technique where material—like plastic filament—is heated and squeezed out through a nozzle, precisely depositing successive layers to form the final object. This method allows for complex shapes, customization, and efficient production. Think of it as drawing or sculpting in three dimensions, using a machine that "extrudes" material to create detailed, durable parts directly from a computer design.
