Development and Simulation of Metallic Mesostructures Manufacturing Process by Integrated Vat Polymerization and Electroforming
, M.Sc. Thesis Sharif University of Technology ; Akbari, Javad (Supervisor)
Abstract
Nowadays, metallic microsystems such as miniature and meso-scale gears, microgrippers, and comb structures constitute a significant portion of key components in various microelectromechanical systems (MEMS). Due to their extremely lightweight nature, small size, high dimensional accuracy, superior performance, and extended lifetime, the manufacturing process of these microsystems has always been a subject of discussion and research. The goal is to enhance the strength and precision of the products while reducing production costs.LIGA and wire-cut electrical discharge machining (WEDM) are two well-known methods for fabricating microstructurs. Despite their advantages, such as high dimensional...
Design and Development of the Process of Manufacturing Microstructures by Electroforming in Molds Made by Additive Manufacturing Technology
, M.Sc. Thesis Sharif University of Technology ; Akbari, Javad (Supervisor)
Abstract
Today, the need to use microstructures in various fields of industry has led many countries around the world to take action to produce micro and miniature structures and make investments in this field, because the small size of the structures, increase production speed and reduces costs. Meanwhile, high-aspect-ratio metal microstructures are widely used in various and influential industries in the world, including the automotive, missile and military chip industries. LIGA and WIRECUT methods are two common methods of producing metal microstructures with high aspect ratio. In the LIGA method, making a mask requires expensive materials and equipment and has complex steps. In addition, the...
