Abstract
Fused deposition modeling (FDM)-based 3D printing is one of the most widely used additive manufacturing (AM) techniques that can build a part with any complexity. FDM-processed parts have a wide range of applications in various fields such as aerospace, medical, automobile, and consumer part industries. However, its application may be restricted due to poor mechanical properties of parts because of the layer-by-layer forming of parts. Due to this, the application of FDM-processed part restricted as end-use functional parts. In the present investigation, an attempt has been made to study the effect of key process variables on the tensile strength of the printed part. Three process variables viz. raster angle, raster width, and layer height have been varied to study their influence on the tensile strength of the PLA part. Further, microscopic examination was carried out to understand the effect of process variables on the fractured surface.
