Additive Manufacturing (3D Printing) in Mechanical Engineering(GRK)

 

_{🔹 Introduction}

Additive Manufacturing (AM), commonly known as 3D printing, is a revolutionary technology in mechanical engineering. Unlike traditional subtractive manufacturing (cutting, drilling, milling), AM builds components layer by layer from digital models, enabling complex shapes, customization, and efficient material use.
