1.Additive manufacturing includes 3D printing technology, but 3D printing is not exactly the same as additive manufacturing
2.Additive manufacturing (AM) is commonly known as 3D printing, which combines computer-aided design, material processing and molding technology, based on digital model files, and uses software and numerical control systems to combine special metal materials, non-metal materials and medical biological materials in accordance with the extrusion Pressing, sintering, melting, light curing, spraying and other methods are stacked layer by layer to produce the manufacturing technology of physical objects. Compared with the traditional processing mode of raw material removal-cutting and assembly, it is a "bottom-up" manufacturing method through the accumulation of materials, starting from nothing. This makes it possible to manufacture complex structural parts that were restricted by traditional manufacturing methods in the past.
3.In the past two decades, AM technology has achieved rapid development, such as "Rapid Prototyping", "3D Printing", and "Solid Free-form Fabrication". Law expresses the characteristics of this technology from different aspects.
4.Additive manufacturing technology refers to a scientific and technological system that directly manufactures parts based on the principle of discrete-stacking and is driven by part three-dimensional data. Based on different classification principles and ways of understanding, additive manufacturing technology has multiple titles such as rapid prototyping, rapid prototyping, rapid manufacturing, and 3D printing. Its connotation is still deepening, and its extension is also constantly expanding. "Manufacturing" has the same meaning as "rapid prototyping" and "rapid manufacturing".
