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

Abstract

A novel cyclodextrin‐derived multiacrylated macromer (Ac‐γ‐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‐γ‐CD‐based formulations are successfully used as innovative inks to reproduce several computer‐aided design files by digital light processing 3D printing.

Sustainable Photopolymers in 3D Printing: A Review on Biobased, Biodegradable, and Recyclable Alternatives

“…Cosola et al. [ 35 ] used acrylated γ‐cyclodextrin (Ac‐γ‐CD) as biobased compound in DLP printing. Up to 30% of this oligosaccharide obtained from starch was mixed with monofunctional methacrylated poly(ethylene glycol) (PEG) as reactive diluent to formulate resins.…”

“…In addition, they can be chemically modified by hydroxyl substitution [68,69]. For example, Cosola et al prepared a cyclodextrin modified with polyacrylate, which can prepare photocrosslinked materials with different morphologies via 3D technology [70]. Yamasaki et al modified cyclodextrin with isophorone diisocyanate and 2-hydroxyethyl acrylate to obtain photocrosslinked cyclodextrin [71].…”

“…Furthermore, the Tanδ curve of ERHO-6 is broader and flatter than the others, suggesting a more heterogenous network with a larger distribution of chain relaxation. [45] The moduli value in the rubbery plateau can be associated with the cross-linking density (ν c ) of the networks, higher the moduli value the higher the ν c . [46] In particular, the statistical theory of rubbery elasticity was used to evaluate the crosslinking density.…”
