3D Meso-Spring – FEMTIKA

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.

Multi-Photon Polymerization

Microfabrication by multi-photon polymerization is a direct laser-write technique which allows 3D structuring of photopolymers at the micro- and nano-scale.

Laser Nanofactory

Multi-Photon Polimerization

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.
