Fabrication of 3D Printer with Two Separate Extruder

Abstract

Three-dimensional printing or additive manufacturing is a process of producing threedimensional
solid objects using design software. Nozzle limitations for simultaneous usage
and relatively low printing speeds are the major problems of fused deposition modelling
(FDM). In this study, an extrusion model with two separate nozzles is used to reduce
deficiencies. The proposed 3D Printer model permits printing with twin different colours and
materials simultaneously without ending the operational process while switching the
filaments. The major advantage of the proposed model is that the two nozzles works
separately it means the bigger part can be create by distributing the work to the both nozzles
to create single object. The proposed extrusion model provides ability to work two operations
at a single time on single 3D printer. This proposed model is very helpful for domestic as
well as for industrial purpose, it means not required to invest in another 3D printer.
