Title: THERMOSETTING COMPOSITIONS AND FORMING THREE-DIMENSIONAL OBJECTS THEREFROM
Abstract:
Thermoset compositions and methods for forming three-dimensional articles via an additive fabrication process, and articles made therefrom are disclosed herein. In an embodiment, a composition comprises a first network-forming component comprising a TPA-based polyester comprising a backbone and having at least 2 polymerizable groups, one or more first network monomers, and a first network initiator. The backbone of the TPA-based polyester comprises the reaction product of a terephthalic acid and a polyol. The composition may further comprise a second network-forming component.
