Throughout the high tech engineering field, instrumentation and high-performance equipment rely on adjustable mounts for fine alignment of optical components. However, current manual or actuated adjustable mounts and mechanisms typically consist of many parts, are voluminous, lack crosstalk-free control of individual degrees of freedom, and are sensitive to mechanical and thermal disturbances. Radical technological innovation is needed to overcome these limitations without a severe penalty in terms of engineering costs. This project develops a design methodology that uses computational topology optimization methods in order to generate multi-degrees of freedom monolithic compliant mechanisms with fully decoupled kinematic adjustment modes. The latter is optimized for dynamic aspects as well as mechanical and thermal stability and can be readily manufactured by additive manufacturing.
