Abstract: The new innovation named added substance fabricating (Additive Manufacturing) is picking up centrality in the mechanical part because of its ability to characterize new upgrades in the plan, creation and strategic issues identified with a particular item. This new zone in modern designing is getting to be usable yet is as yet not effectively pertinent to a wide range of creation frameworks. Added substance fabricating (AM), otherwise called quick prototyping or 3D printing, for the most part alludes to procedures that produce three-dimensional parts by including material bit by bit in a layer by layer design. This unique issue plans to assemble research and advancements in AM, especially identified with new assembling procedures and additionally to elective feedstock materials and items. Polymer and metal-based crude materials and items have been widely researched in AM systems. In this trial work, Conventional screw, nut and washer are delivered by 3 D printer utilizing programming. The fastener nut and Washer is structured by professional E programming and manufactured by 3 Printer. At long last strength of polymer screw and nut gathering was resolved and contrast and steel made fastener and nut get together
