A Multi-criteria decision making approach for 3D printer nozzle material selection

Rapid advancements in 3D printing technology have compelled the manufacturers to search for better nozzle material extruder of printers. Materials ranging from brass tungsten carbide and ruby are primarily used as material. In technology, due major constraints imposed by filament other decisive factors, no single satisfies all desired characteristics a real time application. Thus, it has become crucial select most appropriate with properties enhanced performance. this paper, performance eight candidate materials is evaluated based on nine selection criteria. Entropy method utilized determine criteria weights, whereas, evaluation distance average solution (EDAS) employed identify best suited printer Tungsten emerges out choice, followed titanium alloy (TiAl6V4). This paper also proposes sensitivity analysis establish robustness adopted methodology.
