Abstract

We report direct laser fabrication of free-standing 3D structures in a sol-gel photo-polymer SZ2080, poly(ethylene glycol) diacrylate (PEG-DA-700) and thermo-polymer polydimethylsiloxane (PDMS) without use of two-photon absorbing photo-sensitizers. By estimating the multi-photon and avalanche ionization rates in the focal volume it is shown that bulk structuring of pure materials was achieved via a controlled avalanche. It is shown that several non-photosesitized materials can be combined for fabrication of composite material structures evoking a possibility to create non-toxic biocompatible scaffolds for tissue engineering, transparent microoptical elements and higher damage threshold photonic devices.
