Boronate Esters Dynamic Networks for the Reduction of Mechanical Anisotropy in Vat 3D Printed Manufacts.

ABSTRACT: Vat photopolymerization (VP) is a prominent 3D printing technique known for its high resolution and precision. However, mechanical anisotropy can limit the performance of printed structures by making their mechanical properties dependent on the printing orientation and curing conditions. This study introduces a photocurable material for VP 3D printing, combining dynamic boronate ester-based cross-linking with nondynamic cross-links. The material is synthesized using photoinduced free radical polymerization of a (meth)acrylate-based formulation, incorporating a diboronate ester with two methacrylate functionalities (DBEDMA) and a commercial poly(propylene glycol) diacrylate (PPGDA). The resulting resins exhibit rapid curing kinetics, low shrinkage (5-8%), and tai
