Item 3D Printing & Mechanical Characteristion of Polylactic Acid and Bronze Filled Polylactic Acid Components(Institute of Physics Publishing helen.craven@iop.org, 2018) Aveen, K.P.; Vishwanath Bhajathari, F.; Jambagi, S.C.Rapid prototyping (RP) technologies have emerged as fabrication methods to obtain engineering components within a short span of time. Desktop 3D printing, also referred as Additive Manufacturing (AM) technology is a powerful method of rapid prototyping technique that can fabricate three-dimensional engineering components. Poly Lactic acid (PLA) is a green alternative to petrochemical commodity plastics, used in packaging, agricultural products, disposable materials, textiles, and automotive composites, 3-D printing technology enables fabrication of PLA and bronze filled PLA, which has less tensile and flexural modulus. In order for 3D printed parts to be useful for engineering applications, the mechanical properties of the material will play an important role in the functioning of the components. In the present study, commercial grade PLA & bronze filled PLA has been considered as material for preparation of samples using desktop 3D printer. The samples were tested for their mechanical characteristics like Tensile and flexural strength properties. The test Samples were fabricated using 3D printing with different layer height and with different layer build-up speed. Comparison between the PLA & bronze filled PLA based on the experimental results are discussed and found PLA has superior tensile and flexural property when compared to Bronze filled PLA. © Published under licence by IOP Publishing Ltd.Item Experimental analysis on effect of various fillers on mechanical properties of glass fiber reinforced polymer composites(American Institute of Physics Inc. subs@aip.org, 2019) Aveen, K.P.; Bhajantri, V.; D'Souza, R.; Neelakantha, N.V.; Jambagi, S.Filler materials are the inert materials which are used in glass fiber reinforced polymer (GFRP) composites for modifying the chemical and physical properties of the matrix polymers to reduce material costs, to improve processability, to improve product performance or to simply act as extenders or matrix diluents. Effect of fillers on mechanical properties like tensile strength, flexural strength, tensile modulus, impact strength, hardness was tested by various methods experimentally. The present work focused on fabrication of Glass Epoxy composite with Mother of pearl, fly ash and aluminum powder used as filler material. The Filler material was varied in % composition by 3%, 6% and 9% in the total volume. This study was carried in order to determine the mechanical properties of fabricated composite by conducting Tensile and Flexural tests. The tests showed the composite with aluminum filler material exhibits better tensile property and composite with fly ash filler exhibits better flexural property. © 2018 Author(s).
