Additive manufacturing

Definition

Additive manufacturing, often known as 3D printing, is a process of creating objects by adding material layer by layer, guided by digital models. This method contrasts with traditional subtractive manufacturing, where material is removed to create a part. The versatility and precision of additive manufacturing enable the production of complex geometries and custom components, making it a valuable technique in various industries including thermoelectric device fabrication.
