3D laser lithography is a suitable technology for the production of high-precision micromechanical components, an example being the single-helix three-turn 3D meso-spring for micro-mechanical applications. The design of such a part gives it flexibility, so that these small parts could be used in microrobotics or in watches. Different polymeric materials could be chosen depending on the exact application.
Femtosecond microfabrication in micromechanics applications uses techniques like multiphoton polymerization and selective laser etching to produce flexible and high-precision 3D structures. These structures, made of materials like polymers and ceramics, can be used in various fields like micromechanics and microrobotics and are ideal for applications that require movable assembly-free components.
Multiphoton-polymerization (MPP) is a technology that enables the production of arbitrary shape polymeric structures within submicrometric resolution. First, a photoresist sample is prepared by drop-casting polymer material mixed with a photoinitiator on the glass slide and then pre-baking.
A feasibility study is composed of several steps, including researching methods for fabricating micro-structures, fabricating a micro-structure prototype, measuring and aligning the prototype with technical requirements, and finally preparing a study report.
