DESIGN AND FABRICATION OF 3D PRINTER

Abstract

The project entitled Design and Fabrication of a 3D Printer defines about the different types of D printer being used in the market and the final analysis of the various input and output parameters that has been taken into consideration. It also describes about the present application and the future scope of the 3D Printer. A 2D-sketch of butterfly was been prepared in the Solidworks software which was further extruded into its 3D-model. After converting the 2D sketch into 3D model the file was saved and transferred in the STL (Standard Tessellation Language) file format for the final layer by layer manufacturing in the 3D printer. Fused Deposition Modelling (FDM) type of 3D printer is been used in the project which does the modelling by depositing the filament through heated nozzle layer by layer on the heated plate to form the final object. Thus taking the input parameter as the Nozzle diameter, travel speed and layer height we considered the output parameter as Marching time and did our analysis using Design OF Experiments (DOE). The results after the analysis were like the more nozzle diameter we will use the less machining time will be required with increased layer height and travel speed though with more nozzle diameter the quality of the product would vary a bit but it can be accepted if not much précised or complex design is required. Similarly, the less diameter would require more machining time with less layer height and less travel speed, though the quality of the product will be excellent normally also and for more complex and intricate designs as well.
