Impact of compression and bending behavior on fused deposition modeling of 3D printed components

Abstract

The fast-prototyping technology known as additive manufacturing (AM) was first created as a tool for developing and analyzing ideas. Fast manufacturing is being facilitated by the recent advancement of AM technologies like Fused Deposition Modelling (FDM). In this paper, the material used as PLA biodegradable material which is made up of plant starch, cost also less when compared to other materials, and process parameters are considered Infill Percentage, Raster Angle, and Layer Thickness. Infill percentages are 20, 40, 60, 80, and 100, Layer heights are 120 µm, 180 µm, and 300 µm and raster angles are angles (00,00) (450,00) and (900,00). By using the selected parameters, 90 samples are constructed by using FDM and tested by using Flexural and Impact. The PLA material properties of each component were examined and components of 300 µm underwent SEM and examined whether the external surface was deposited correctly or if any imperfections are there. Examining all tested PLA components mechanically and SEM reports concluded that compression, flexural tests, and microstructural behavior are good at raster angles (00,00), 80% infill, and 120 µm this reduces material deposition and the time of printing sample.
