Multiple-layer laser direct writing metal deposition in electrolyte solution

The development of the miniaturized product, such as microelectronic component marks a new era in processing technologies. A wide range of miniaturized products is being fabricated by high-yield, cost-effective and high-resolution rapid prototyping (RP) techniques in which the product design and development cycle has been accelerated in the absence of tooling or apparatus. In this paper, a new, laser-based thin film deposition within a fluid environment for growing prototypes is described. The effects of the laser-processing conditions and fluid properties on the material deposition rate as well as microstructure features are presented. Also, the mechanism involved in the new process is discussed.
