Micro-machining using photo-polymerization and metal jet deposition

This research work deals with the development of a simple and practical method for manufacturing micromechanical parts using different methods. The first method is a mask-based method in which an image is transferred to a liquid photopolymer by irradiating a UV laser through a patterned mask. The irradiated portion of the photopolymer is then solidified and it becomes a high aspect ratio polymer structure. In the second method, high aspect ratio and three-dimensional polymer structures are produced using direct focused UV laser beam writing. The accuracy of the solidified polymer when using these methods is examined. These methods produce micromechanical parts of produced shapes. In the third method, three-dimensional micro models are formed by metal jet deposition. The metal used in this experiment is solder. Some examples of three-dimensional products, electric circuits and functional gradient material are shown.
