Abstract

Additive manufacturing is an advanced manufacturing process of making three dimensional solid object from a digital file.3D printing is one of the process in Additive manufacturing. The creation of a 3D printed objects is achieved using additive processes. In fused deposition modeling a filament in the form of wire will be extruded through the nozzle with the help of hot end. External force is provided to wire by rollers and bearings. In wire extrusion process back pressure is created and this will make wire to reduce its movement. With that external force the filament is extruded .The usual problem facing in 3D printing (Fused Deposition Modeling) is clogging of nozzle. Whenever the nozzle is clogged it has to be cleaned and then had to restart the print from beginning. There are some situations where the print is about to end but it will stop due to blocking of nozzle. If we observe that mainly blocking occurs due to not having enough and un-uniform pressure to push the filament into the extruder. By changing the feeding system that means instead of using wire extrusion here there is the use of granules and hopper. Based upon the principle of feed system of injection molding machine this feed system is designed. This is the basic info regarding the changing of feed system.
