| Abstract Scope |
Limited materials available for light-based additive manufacturing methods have driven research into new chemistries beyond commonly used acrylate-based resins. Recently developed photoinitiated ring-opening metathesis polymerization (photoROMP) is a promising technique due to its ability to produce a wide range of polymers with superior mechanical properties and chemical stability. However, current photoROMP resins typically exhibit short pot lives and longer activation times that make them challenging to implement for some additive manufacturing applications. In this work several acid-activated ruthenium catalysts were evaluated in dicyclopentadiene resins for digital light processing (DLP) vat photopolymerization 3D printing with commercially available PolCat identified as an ideal catalyst. In combination with a photoacid generator, PolCat was used to demonstrate long lived resins with low activation times, allowing for larger and complex prints with a wide array of material properties. |
