Experimental Analysis of Low Melting Metal Alloy for Fused Deposition Modeling based Process

Fused Deposition Modeling (FDM) is one of the rapid prototyping technologies which use an additive manufacturing approach. In recent years, FDM has become one of the most widely-used rapid prototyping methods for various applications such as bio-printed organs, piezoelectric components, etc. FDM, which offers the opportunity to design and introduce new materials, including composites. The material commonly used in FDM is Acrylonitrile butadiene styrene (ABS), Polylactic acid (PLA) and some low melting metal alloys. The low melting alloys containing bismuth, tin, and indium, etc. Many of the paper deals with 3D printing using thermoplastic only. And some papers suggest that printing could be possible with tin and bismuth. In this paper, Bi-Sn alloy is used in the composition of 50% bismuth and 50% tin. The Melting temperature of Bi-Sn alloy is between the ranges of 138�c to 170�c. Bi-Sn alloy is used as a filament of 3 mm diameter to do “Experimental Analysis of Low Melting Metal Alloy for Fused Deposition Modeling Based Process�. This work is done to reduce material wastage and labour costs and manufacture the complex shaped object.
