Development of a Low Cost Dual Nozzle FDM Printer


One of the basic types of printers are the Fused Deposition Modeling (FDM) printers which are most widely available due to its low cost and easy use also. A FDM 3D printing is a horizontal and vertical printing technology in which an extrusion nozzle moves over a build platform. The process employs the use of thermoplastic material that melts and is then forced out in layers to create a 3D object. This printer will improve the printing speed to the machine and also it’ll be able to print multiple colors simultaneously. FDM employs a digital design that is sent to the 3D printer. There are numerous polymers used, including ABS (Acrylonitrile Butadiene Styrene), PETG (Polyethylene terephthalate glycol), PEI (Polyetherimide), and PEEK (polyetherether ketone). Plastic threads are fed from a coil and through a nozzle to create these. The filaments are melted and fed onto the build platform or table, which includes the base and the nozzle, both of which are controlled by a computer. The computer works by converting the object and its dimensions into coordinates that the nozzle and base can follow.
