Abstract

Due to its numerous benefits over any traditional production processes, additive manufacturing (AM) technology is essential to the current sustainability of Industry 4.0. Common polymers used in procedures requiring thermoplastics, or plastics that are treated by heating to a semi-liquid condition and close to the melting point, include polycarbonate (PC), acrylonitrile butadiene styrene (ABS), poly ether ester ketone (PEEK), polyetherimide (ULTEM), and nylon. These materials have different engineering application in the field of Bio-medical, Automotive, and Aerospace Engineering to cater the requirements of advanced manufacturing technology. There is great demand for the materials which are bio-degradable considering with environmental factors. Polylactic acid (PLA) is one of the bio degradable material finds major applications in Industries. Hence to meet the demand in production of bio-degradable materials, this work attempts to study the analysis on mechanical properties of Polylactic acid (PLA) fabricated through fusion deposition modelling technique with different build orientations. The results have revealed that the test specimens built on x-axis has better tensile and yield properties compared to Y-axis and Z-axis. Impact strength of the material with different orientation does not have significant differences.
