Selective Laser Sintering (SLS)Fused Deposition Modelling (FDM) is the focus of this particular blog.3D printing using FDM essentially implies that the object being printed is fused together by printing layer after layer in a certain pattern.Objects are created by extruding layer upon layer of the heated material on the build tray or printing bed of the 3D printer.FDM 3D printers use a filament of certain material, usually plastic, which is passed through a hot end, to melt.The melted filament material is used to make layers which are then fused together to give the object its final shape.A wide variety of materials can be used for FDM 3D printing like plastics, pastes and some metals as well.FDM 3D printers can be fitted with a wide variety of extrusion systems or extruders like filament extruders, pellet extruders, chocolate extruders and paste extruders depending on the required model to be printed.Scalability is the biggest advantage of using the FDM technique for 3D printing.None of the other available 3D printing techniques like SLS and SLA, can be scaled like FDM, without major issues propping up.
