Additive manufacturing is one of the fastest growing manufacturing methods in the world especially in engineering fields. Nowadays 3D printers play overall prominent roles everywhere, especially in mechanical stream. It is one of the efficient and cost-effective ways for the development of future automated production with minimal material usage. We all can understand the demand for this method while looking through the various researches performed in many universities and industries for better development and high-quality production. In this Thesis we are focusing on Fused Deposition Modelling (FDM) 3D printing method. This is the modelling of 3D components using polymers or plastic material filaments. In this research we are creating a Polylactic Acid (PLA) and two other varieties of filament which are the highlights of this Thesis and are called PLA/PBAT blended filament. Polybutylene Adipate Terephthalate (PBAT) is a type of material which is also biodegradable polymer similar to the PLA material with many properties. In this work the filament is created in two combinations such as PLA 80 Wt% PBAT 20 Wt% and PLA 90 Wt% PBAT 10 Wt%; and the interesting fact is that these two PLA/PBAT combinations of filaments are not available in the market for sale or for commercial use. While mixing PLA with PBAT, the overall properties of the filament will change, and to increase the compatibility, further addition of compatibilizers can enhance the mechanical properties (Joncryl-4368-F). When there is change in this polymer combination with ductile material PBAT, the properties such as elasticity and viscosity increase, hence the failure chance of the PLA (Brittle character) will become lower with increase in ductility. Hence based on this research the overall study and benefits of this new developed filament will be studied, and this result can be used in a variety of technical fields. Moreover, I preferred this topic because of its future scope and importance for the coming generation. All products can be made (3D Print) with low cost, and the product can be used for a long term. The results derived from this project can be used for further research and studies for creating better products.
