Material Processing

Definition

Material processing refers to the techniques and methods used to manipulate and transform materials into desired forms or structures. In the context of acoustic levitation, material processing involves using sound waves to control the movement and arrangement of materials, allowing for precise manipulation without physical contact, which can lead to innovative applications in manufacturing and scientific research.
