Evaluating the Sustainability and Economic Integration of Additive MaAdditive Manufacturing (AM) or 3D printing is transforming the landscape of contemporary industrial manufacturing. Having originated in prototype making, AM has evolved to denote a variety of technologies with increasing application across a wide spectrum of industries—aerospace, medicine, automotive, energy, etc. This dissertation is a complete, multi-faceted analysis of AM, covering its technical underpinnings, economic promise, supply chain disruptions, and green possibilities. Against the backdrop of accelerating digitalization, changing consumer mindsets, and global demands for sustainability, AM presents itself as both a reaction to and a catalyst for fundamental transformation of product design, production, and distribution.
