Tensile analysis of 3D printed thin cylinder at different percentage of infill’s

Abstract

The Additive manufacturing (AM) technology familiarize many innovative and monetary gains when compared to conventional manufacturing methods. This research work affords an insight for supplanting metallic materials like stainless steel, titanium, carbon steel by means of durable plastics namely ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid). The mechanical behaviour of additive manufactured ABS and PLA, produced by fused deposition modelling are investigated at different densities. The main idea of this research work is to identify the mechanical characteristics of ABS and PLA at various conditions and to develop 3D printed thin walled cylinders by fused deposition modelling. The thin walled cylinders contribute its applications in pressure tanks and other low-pressure processing equipment. The fabrication of thin walled cylinders involves parameters such as maximum operating pressure, temperature, density, and print orientation. The tensile and flexural tests are carried over AM thin walled cylinders to estimate its mechanical properties, durability and corrosion resistance behaviour. It is found that the AM thin walled cylinders fabricated using ABS and PLA has better flexibility, less weight, high impact resistance and corrosion resistance, and durability when compared to metallic materials in very less production time and cost, the wastage of materials is also being reduced. Results shows that the ABS has better tensile and flexural strength than PLA. This methodology provides a better approach for fabricating various components through bio degradable ABS and PLA to enhance modern manufacturing industries.
