Optimization of the Print Quality by Controlling the Process Parameters on 3D Printing Machine

Abstract

Fused Deposition Modelling is one of the most widely used Additive Manufacturing technologies for various engineering applications. The present work investigated the aesthetics of the cube. In FDM process of printing, one of the major problems faced in printing the objects, specifically the cylindrical objects is the non-sticking of the preliminary layers of the molten filament on to the hot bed. There are other serious problems which occur while printing they are under extrusion, over extrusion of filament from heated printing nozzle, gaps occurring in the top layers of the printed object, stringing or oozing of the extra filament from the heated nozzle, overheating of print bed, Layer shifting, layer separation and splitting, grinding filament, clogged extruder, extruder stopping in the middle of printing process, gaps between infill and outline, etc. In this study, the above-mentioned problems are observed and identified through Pareto analysis that on the machine, the non-sticking of the preliminary layers to the hot bed occurred more, thus solutions are provided to avoid this problem which in turn has helped to reduce various other problems occurring while printing the 3D objects.
