Description Three-Dimensional Printing (3DP) is one of the most promising innovative technologies, used
not only in prototyping, but also in the production processes. The main advantages of this new
technique are the high versatility, the progressive printers’ price knock off and the
considerable saving of raw materials. The exploitation of new functional materials, for example
temperature-, light- and pH-responsive polymers, is one of the most interesting survey field.
Azo-based scaffolds have been reported to provide well-defined either photohardening or
photosoftening 3D materials.
This project will carry out in collaboration between the University of Torino and Politecnico
di Torino.
The first part consist of organic synthesis of boronic-functionalized azodye and its chemical
and optical characterization to fully understand its properties in different solvents and its
thermal and photostability.
In the second part, the 3D printing process is optimized in term of formulation and printing
parameters to obtain self-standing hydrogels with good final good precision and fidelity to the
original CAD file. Then, the ability to self-repair under visible light irradiation will be tested and
evaluated, using different wavelengths from various light sources. At the same time, the
shape-memory properties will be tested to explore potential double responsive devices.
