Abstract: Additive Manufacturing (AM), commonly known as 3D printing, represents a revolutionary shift in how components are designed, prototyped, and produced. Unlike subtractive methods, AM constructs parts layer-by-layer, offering design freedom, minimal material waste, and rapid customization. This paper explores the various additive technologies—fused deposition modeling, selective laser sintering, and stereolithography—highlighting their suitability across industries such as aerospace, healthcare, and automotive. Emphasis is placed on the growing trend of integrating AM into existing manufacturing ecosystems to support low-volume, high-complexity part production. Moreover, the paper investigates current limitations, including material constraints, surface finish quality, and scalability challenges. Finally, it discusses ongoing research aimed at overcoming these barriers and enhancing AM's industrial applicability.
