In today’s modern era 3D printing plays a major role in manufacturing a prototype for components that may be subjected to real-time applications. The most commonly used 3D printers areFused Deposition Modeling (FDM) printers because of its cost and easy feed of materials in the form of the filament.On the brighter side,binder jet printing is a developing technology, which uses the principle of traditional inkjet printing. The major difference is that it applies a binder material layer by layer on abase metal powder to form a 3D object.In this paper,a binder material study suitableto have a proper homogenous formation when applied on a metal powder was performed. Both additive and binder property studies have been done and produced in this report.Five sample binder materials in different ratios were synthesized and characterized for the rheological parameters. For inkjet printability, the printable parameter “Z” should be in the range of 1 < Z < 10. Two of the synthesized samples S1 and S5 in which the additive ratio is higher are found suitable for binder jet printing. Droplet analysis in Flow 3D was carried out to ensure the drop formation properties.
