Additive Manufacturing

Definition

Additive manufacturing, also known as 3D printing, is a transformative approach to industrial production that enables the creation of lighter, stronger parts and systems. It is a process of creating three-dimensional objects from a digital file by building them up layer by layer.

Why It Matters

Additive manufacturing allows for the creation of complex, customized designs that are impossible to produce with traditional manufacturing methods (like milling or casting). It enables rapid prototyping, on-demand manufacturing, and highly optimized parts.

Contextual Example

An aerospace company can use 3D printing to create a lightweight yet strong bracket for an airplane. The design can be optimized by software to use the minimum amount of material necessary, something that would be impossible to manufacture traditionally.

Common Misunderstandings

• 3D printing is a form of additive manufacturing.
• It is contrasted with "subtractive manufacturing," where material is removed from a larger block to create a shape.
