What is additive manufacturing?

Additive manufacturing refers to a process that builds parts and products by adding material layer by layer, typically using techniques such as 3D printing. This approach contrasts with traditional manufacturing methods that often involve subtracting material from a larger block (like machining or milling), where material is removed to achieve the desired shape.

The essence of additive manufacturing lies in its versatility, as it can use a variety of materials, such as plastics, metals, and ceramics, thus broadening the applications and potential for creating complex geometries that may not be possible with traditional methods. This capability allows for design innovations and efficiencies that can revolutionize production processes across various industries.

While it is common to use metals in additive manufacturing, the process is not limited to this material alone, which is why the focus solely on metal fabrication does not encompass the broader definition of additive manufacturing. Similarly, traditional methods of machining are distinctly different from the additive approach, which emphasizes building rather than removing material.
