Abstract
Here we present direct laser fabrication of 3D microstructured scaffolds consisting out of a few polymeric materials owning different biological properties. Direct laser writing in photo/thermo-sensitive materials using ultra short light pulses of high repetition laser provides unmatched flexibility in controllable 3D microstructuring in a variety of bio-materials [1], as well as manufacturing throughput empowers overall structure size of more than 1 mm3, making it an attractive method to fabricate scaffolds for cell studies and tissue engineering applications [2, 3]. In this work, a femtosecond direct laser writing system was supplemented by a machine vision [4] to relocate the sample between different fabrication steps.
