The acronym 3D printing refers to the additive manufacturing technology that creates three-dimensional objects from digital models. This process involves layering materials, such as plastics or metals, to build up the final product. 3D printing revolutionizes manufacturing by reducing waste, enabling rapid prototyping, and allowing for complex designs that traditional methods cannot achieve. It is applicable in various industries, including healthcare, aerospace, and automotive, demonstrating its versatile impact on production processes.
