Material extrusion is an additive manufacturing (AM) methodology. 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. Fused filament fabrication (FFF) and fused deposition modeling (FDM) are two examples of …
What Is Material Extrusion 3D Printing? | Additive Manufacturing
As the name implies, material extrusion extrudes a material through a nozzle (or orifice) and selectively deposits material layer-by-layer to form an object. Material extrusion is kind of like squeezing toothpaste out of the tube, except that plastic hardens a lot faster after it is extruded and cools down.
