3D Microfabrication is the process of creating three-dimensional structures with microscale features and dimensions, typically on the order of micrometers or nanometers. It involves the use of advanced technologies, such as lithography, etching, deposition, and other methods, to create structures and devices with a wide range of applications. 3D Microfabrication can be used to produce components for fields such as medical devices, microelectromechanical systems (MEMS), consumer electronics, and optical components.
