| 500 ## - GENERAL NOTE | |
| General note | From the past few years, Additive Manufacturing (AM) or 3D printing has<br/>achieved a significant role among the latest emerging technologies of the<br/>fourth industrial revolution. 3D printing strategy allows us to build<br/>components of various materials without any geometrical constraint. This<br/>feature is unique in the field of industrial production, and it has transformed<br/>the traditional manufacturing concept of mechanical design permitting<br/>lightweight components and improving stiffness. Moreover, another<br/>advantage of additive manufacturing is decreased production waste and<br/>energy consumption. The Nickel based Super Alloy powder has its wide<br/>applicability in the defense industry and mainly Aero-Engine components.<br/>This can also be used for biomedical, power generation and automotive<br/>applications. Nickel and its alloys are useful due to their properties at elevated<br/>temperatures. The aim of this research was to develop the build parameters of<br/>Nickel based powder and successfully print functional parts using Selective<br/>Laser Melting (SLM) process. The properties desired for the functional part<br/>have been verified through mechanical testing. The print worthiness of this<br/>powder along with desired results achieved through this research has led to<br/>qualified printing of metal parts for high temperature applications. In the<br/>presented thesis, the objective was to conduct a series of experiments to<br/>develop parameters for printing Nickel based superalloy K465 powder for<br/>aero-engine applications. The properties that were evaluated against the<br/>printing parameters include Actual Density measurement, Microstructure and<br/>Tensile values. The best samples were optically viewed to look for<br/>microstructure. Alongside metallography, UTS samples were printed to carry<br/>xv<br/>out mechanical testing of the best samples. The experiment yielding finest<br/>results was chosen for functional part printing. Though additive<br/>manufacturing of nickel-based superalloys presents significant technological<br/>advancement, their unique material behavior and properties also present<br/>several common challenges like fusion of layers, microstructure control,<br/>residual stress and cracking during 3D printing that require careful<br/>consideration and process optimization. The K465 superalloy powder is also<br/>prone to cracking which was faced during this research. Though higher preheat temperatures were provided to mitigate this issue, cracking couldn’t be<br/>avoided due to available SLM limitation. To avoid this challenge, the further<br/>optimization of developed K465 parameters can be carried out through EBM<br/>process and even through more R&D and advanced strategies at SLM<br/>machine discussed in this thesis. These studies will be crucial for optimizing<br/>K465 additive manufacturing processes and ensuring the production of crackfree, high-integrity components for the most demanding applications. |
