👉 Add engineering, also known as additive manufacturing or 3D printing, is a process of creating three-dimensional objects from digital designs by sequentially adding material layer by layer. This method contrasts with traditional manufacturing techniques like subtractive or formative processes, which involve removing material from a solid block or shaping it through cutting or molding. Add engineering allows for the creation of complex geometries and customized parts with high precision, reduced material waste, and faster prototyping cycles. It is widely used in industries such as aerospace, automotive, healthcare, and consumer goods for producing intricate components, reducing costs, and enabling rapid innovation.
