Invited Talk- Toward the fabrication of complex microdevices via two-photon lithography, by Prof. Dr. Marco Carlotti

Abstract: Direct laser writing (DLW) is a powerful and versatile additive manufacturing technology that allows the on-demand printing of precise and complex 3D architectures at the micro and nanometer scale, with small feature size and high lateral resolutions. Thanks to the design freedom, the high-throughput and the flexibility in terms of the materials employed, this technological platform is becoming increasingly appealing for the fabrication of patterned surfaces, biomimetic structures, metamaterials and functional microdevices. Particularly intriguing is the possibility of employing functional responsive materials and control them electrically by combining them with integrated circuits. This synergy between material and computational intelligence can bring to life a new generation of MEMS and microrobots that can be prototyped fast and on-demand. As the complexity of a device increases, however, one must devise new fabrication methodologies for that can allow the combination of different materials and sustain multiple fabrication steps without damaging or changing their properties. During this seminar, we will talk about the potential of DLW for the fabrication of functional microdevices and discuss different methodologies that one can employ to fabricate complex devices comprising different materials and capable of achieving non-trivial functions.
