Multiacrylated Cyclodextrin: A Bio-Derived Photocurable Macromer for VAT 3D Printing

A novel cyclodextrin-derived multiacrylated macromer (Ac-gamma-CD) is successfully prepared and tested for the generation of highly crosslinked materials by means of UV-curing. The high photoreactivity of the macromer under UV-light irradiation is confirmed by means of real-time photorheology. Moreover, dynamic mechanical thermal analyses proved that the properties of the thermosetting networks can be easily tailored by varying the concentration of the macromer in the precursor formulation. Finally, different Ac-gamma-CD-based formulations are successfully used as innovative inks to reproduce several computer-aided design files by digital light processing 3D printing.
