Thermoset compositions for 3d printing
A recently granted patent (Publication Number: US11999861B2) discloses a composition designed for creating three-dimensional objects through an additive fabrication process. The composition includes a first network-forming component consisting of a TPA-based polyester with specific polymerizable groups and molecular weight, along with first network monomers and initiators. Additionally, a second network-forming component with distinct polymerizable groups and initiators is included in the composition. The patent emphasizes the precise combination and proportions of these components to achieve desired mechanical properties in the final product.
Furthermore, the patent outlines specific claims related to the composition, including the use of a photo-initiator as the first network initiator, the mechanical properties of the resulting film, the presence of endgroups in the polymerizable groups, and the molecular weight range of the TPA-based polyester. The claims also detail the composition's components, such as the first network monomers and their molecular weights, as well as a method for forming three-dimensional objects using the disclosed composition. By providing a detailed breakdown of the composition and its intended application in additive manufacturing processes, the patent offers valuable insights for researchers and manufacturers looking to enhance the quality and performance of 3D-printed objects.
