The multiphoton polymerization technique with hybrid polymers in combination with pyrolysis enables the removal of the organic part of the polymer and produces ceramic structures. Structure shrinkage during pyrolysis is homogeneous and is approximately 25%. This property gives precise control of the structure geometry and obtains even higher resolution than the resolution in the polymeric parts which could be up to 100 nm. In contrast with polymers, ceramic structures show high mechanical rigidity, 1000 times more rigid than polymeric material. Ceramic structures are suitable for the fabrication of micromechanical parts.
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.
Applying for Industries
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.
