Abstract Scope |
Additive Manufacturing (AM) is a rapidly growing manufacturing technique. Direct energy deposition (DED) is an important method in additive manufacturing. This research compares the Mechanical Properties like tensile strength and hardness of additively manufactured Al-12Si Aluminum alloy by DED method and pressure die casting (PDC) method. The DED and PDC fabricated parts showed similar ultimate tensile strength and young’s modulus if load direction in UTM machine is same as building directions, although other mechanical properties are slightly differing in their values. Mechanical properties of fabricated objects made by reused powders also exhibited similar values to those manufactured by unused powder. Hardness comparison of both the modes has yet to be carried out. Also, the analysis of influence of print orientation in these properties will also be carried out through various experiments.
