3D printing allows for the creation of physical objects from digital files. It offers advantages like less waste, new designs, and on-demand manufacturing (Paragraphs 1-3). The document discusses how 3D printing could impact customs procedures through shorter supply chains and increased raw material shipments as more localized production occurs (Paragraphs 8-10). Potential solutions are proposed, such as revising supply chain management and customs regulations to address changes from the rise of 3D printing and personalized manufacturing.
