3D Printing

Definition

3D printing is a manufacturing process that creates three-dimensional objects from digital models by layering materials, typically plastics or metals, in precise shapes. This innovative technology allows for rapid prototyping, enabling designers and engineers to create prototypes quickly, test their functionality, and make modifications before final production. It revolutionizes traditional manufacturing by reducing waste, lowering costs, and allowing for complex designs that were previously difficult or impossible to achieve.
