Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF) is a material extrusion process that commonly uses additive manufacturing. FDM uses thermoplastic polymers as filament stored in a reservoir or container. The filament is extruded from the print nozzle by application of pressure at specific temperatures. The object to be printed is governed by various material and machine parameters. The material to be printed is continuously extruded through the extruder nozzle of the printer through two rollers moving in opposite directions. The filament extruded on the built platform is stacked layer-by-layer until the formation of the object. The printing takes place as CAD model from the software is sliced, which acts as an input to the 3D printer, causing the print nozzle to movein desired arrangements and paths based on the G-Codes obtained from the slicer software. Few machines also possess dual extrusion or two extruders providing printing of different materials based on the needed properties of the product. The liquefaction or melting of the filament at temperatures varies with the materials to be extruded. The properties of the manufactured parts depend on the material used and its parameters, such as mechanical andthermal properties. Layer resolution, build orientation, temperature, raster angle, and air gap, known as the machine parameters, play the decisive role for a good printed FDM part.Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF) is a material extrusion process that commonly uses additive manufacturing.
