Unlocking the Alchemy: An Analysis of Stainless Steel Creation via Fused Filament, De-Binding, and Sintering

Abstract

Abstract Metal, plastic, ceramic, and composite components are made using the additive manufacturing process known as fused deposition modeling (FDM), which boasts zero waste and no need for molds. FDM has gained international attention for both complex and simple metal part production due to its simple setup and approachable process. Feeding filament into a 3D printer results in the extrusion of green components. These "green" components go through a process called thermal de-binding, which is a crucial step in the conversion of filaments into metal parts. Differentiating factors like heating rate, holding duration, and temperature play a role in the successful components made of 316L SS green Ultra fuse are thermally de-binded without creating any defects. Perfect thermal de-binding is accomplished by meticulously controlling these parameters.After de-binding, the Ultra fuse 316L metal is sintered to produce pieces with remarkable characteristics, including a peak, a hardness of 187.88 HV,density of 8.67 g/cm3, and a tensile strength of 570 MPa. This combination of FDM, precise thermal de-binding, and subsequent sintering demonstrates the potential to produce strong metal components with outstanding mechanical properties.
