Additive manufacturing techniques

Definition

Additive manufacturing techniques refer to a category of processes that create objects by adding material layer by layer, as opposed to traditional subtractive manufacturing methods. This innovative approach allows for complex geometries and customized designs, making it particularly suitable for flexible and stretchable antenna designs where lightweight, conformable, and high-performance structures are essential. The use of various materials, such as conductive inks and polymers, further enhances the capabilities of additive manufacturing in producing functional electronic components.
