What is extrusion material?

Material extrusion is an additive manufacturing (AM) methodology where a spool of material (usually thermoplastic polymer) is pushed through a heated nozzle in a continuous stream and selectively deposited layer by layer to build a 3D object.

How are extruded materials called?

One layer is deposited on top of a previous layer until the object’s fabrication is complete. Material extrusion is known as Fused Filament Fabrication (FFF) and is one of the most popular processes for hobbyist-grade 3D printing.

What is extrusion in engineering materials?

Metal extrusion is a forming process in which we force a metal (either hot or cold) through a die. This imparts the die shape to the extruded metal as it passes through the cavity. The material emerging from the die is known as “extrudate”. The metal endures compressive and shear stress to achieve the die shape.

What is rolling and extrusion?

Rolling can be used to offer desired shape to the metal like section, T-section, L-section, channel section. Its also practiced in order to provide final shapes to applications like rods, sheets, strips and pipes. Extrusion is a manufacturing process used to create objects of a fixed cross-sectional profile.
