Among all types of 3D Printings, FDM is the most effective technique to print prototypes as well as custom thermoplastic components. Some major types are SLA (Stereolithography), FDM/FFF (Fused Deposition Modeling/Fused Filament Fabrication), Material Extrusion, Binder Jetting, Powder Jetting, Direct Energy Deposition, etc. Depending upon their usage, there are many types of 3D printing.

In earlier 1980s, additive manufacturing was mostly used for the manufacturing of prototypes, but, in these years, their usage has increased due to their precision, repeatability and production costs. Knowledge from this study will help to choose between pellet extruder and filament extruder which fulfils requirement and which types of pellet extruder have to install to 3D printer depending on its type and requirement.ģD printing is also termed as Additive Manufacturing. This paper provides in detail information about FDM and its types, difference between pellet extruder and filament extruder, their advantages and disadvantages, information about some pellet extruders and type of FDM printers they are suitable for. Most of the FDM 3D printers use plastics in the form of wire like filament for making 3D prints. Whole purpose of this paper is to provide information about installation of a miniature pellet extruder to a 3D printer especially in FDM 3D PRINTERS instead of filament extruder. But, by installing a pellet extruder instead of filament extruder reduces cost of printing process that is 1 kg of PLA pellets cost around 4€ while 1 kg of PLA filament cost around 22€ also, can print wide ranges of materials, increase in speed of prints, chance of recyclability when compared to filament extruder. FDM (Fused Deposition Modeling) is one type of 3D printing which uses plastics in the form of wire like filament by an extruder for making 3D prints.

3D Printing is the trending technology in this generation and its usage is increasing day-by-day because it reduces cost of production.
