Micro-accumulative manufacturing technology based on optical pressure

Optical forces and optical pressure could be used to guide and transport different kinds of micron-sized particles, and array or accumulate them to build 2D/3D microstructures, which represents a new approach of micro-manufacturing. The so called laser-guided direct writing technology is also included. This combines the enabling technologies and rapid prototyping manufacturing technologies, and has been explored widely. The principle of this technology, recent research, the key points and application prospects are reviewed.
