Micro-Fabrication of Spray Cooling Nozzles for High-Power Diode Laser Arrays

摘要

An important growing field in today's engineering is the development of Micro-Electrical and Mechanical Systems (MEMS). Over the years there have been many different fabrication processes that have been developed to meet these new demands. Most of the current micro-fabrication techniques work well for simple two-dimensional components. However, the demand for more complicated three-dimensional parts requiring a high aspect ratio requires that a new approach must be taken to make these ideas a reality. A novel fabrication method was developed in the late 1980's called stereolithography. This process involved using a low power laser to introduce free radicals in a polymer in which the molecules would cross-link and become solid. Using this ideal the stereolithography process was developed by 3D Systems to fabricate three- dimensional parts in a layer-by-layer manner.
