FDM (Fused deposition modeling) is a material extrusion method of additive manufacturing where materials are extruded through a nozzle and joined together to create 3D objects.
A typical FDM 3D printer, therefore, takes a polymer-based filament and forces it through a heated nozzle, which melts the material and deposits it in 2D layers on the build platform. While still warm, these layers fuse with each other to eventually create a three-dimensional part.
In particular, the “standard” FDM process distinguishes itself from other material extrusion techniques, such as concrete and food 3D printing, by using thermoplastics as feedstock materials, usually in the form of filaments or pellets.
Generally accepted as the simplest way to 3D print stuff, FDM is accessible, reasonably efficient, and widely popular.
