“…Nickel-based super alloys are used in the development of aircraft exhaust valves and turbine rotors due to their high creep resistance at higher temperatures [12]. Research has been carried out on improving the microstructure and mechanical properties of stainless-steel alloys [13][14][15][16][17][18][19], aluminum alloys [20][21][22][23][24][25][26], titanium alloys [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41], and nickel-based super alloys [42,43] using different techniques like adding carbides [44][45][46][47], alloying elements [48][49][50][51], and heat treatments [20,21,42]. Conventional fabrication involves multiple processes and is time consuming.…”

To improve the microstructure and mechanical properties of fundamental materials including aluminum, stainless steel, superalloys, and titanium alloys, traditional manufacturing techniques have for years been utilized in critical sectors including the aerospace and nuclear industries. However, additive manufacturing has become an efficient and effective means for fabricating these materials with superior mechanical attributes, making it easier to develop complex parts with relative ease compared to conventional processes. The waste generated in additive manufacturing processes are usually in the form of powders, while that of conventional processes come in the form of chips. The current study focuses on the features and uses of various typical recycling methods for traditional and additive manufacturing that are presently utilized to recycle material waste from both processes. Additionally, the main factors impacting the microstructural features and density of the chip-unified components are discussed. Moreover, it recommends a novel approach for recycling chips, while improving the process of development, bonding quality of the chips, microstructure, overall mechanical properties, and fostering sustainable and environmentally friendly engineering.
