Abstract

Fused Deposition Modeling is one of the widely used extrusion-based additive manufacturing technique. FDM is widely used to create prototypes with any complexity. The application of FDM can also be extended for the rapid manufacturing application. The application of FDM may be restricted due to anisotropy in mechanical properties of the printed part. The mechanical performance of the FDM printed part is influenced by several process parameters. In the present investigation effect of the build orientations on the mechanical properties of the printed part have been investigated. Three build orientations X (Flat), Y (on edge) and Z (upright) have been considered to measure their influence on the mechanical strength of the printed PLA part. Analysis of result revealed that part printed in X direction has higher tensile and impact strength over the part printed in Y and Z direction. Further, it is also observed that the fracture pattern is also significantly affected by the build orientation. Inter-layer failure mode has been observed with x and y orientated specimen while trans-layer failure mode has been observed for z-orientated specimen.
