Additive Manufacturing in Engineering: Transforming Design and Production
Author(s): Arvind Krishnan*
Additive Manufacturing (AM), commonly referred to as 3D printing, is revolutionizing engineering by enabling the direct fabrication of complex geometries from digital models. Unlike subtractive manufacturing, which removes material from a solid block, AM builds objects layer by layer, reducing material waste and production time. Initially confined to prototyping, AM has evolved into a viable method for end-use production in industries such as aerospace, automotive, biomedical, and energy. Its flexibility allows for mass customization, lightweighting, and integration of complex internal structures impossible to produce through traditional methods. This article examines AM technologies, applications, advantages, and the challenges that must be overcome for broader adoption... View More»
