| Abstract Scope |
Material jetting is an additive manufacturing technique that can fabricate complex parts with multiple material compositions and high resolution. Formulation of inks for material jetting requires optimization of properties like density, viscosity, and surface tension for optimal droplet formation. Commonly, inks for material jetting will contain diluents to lower the viscosity. However, in some cases, such as dicyclopentadiene (DCPD), the neat monomer’s viscosity and surface tension are too low for optimal jetting. We explore different approaches to optimize DCPD inks in order to achieve an ink formulation suitable for jetting. We investigate approaches including the addition of low molecular weight liquid rubbers, the addition of DCPD oligomers synthesized via frontal ring-opening metathesis oligomerization (FROMO), and rapid viscosity modification, where a low loading of catalyst is added and then quenched, followed by a latent catalyst for polymerization during printing. |
