Application: Inks for 3d printing having high modulus and dispersion stability (Patent ID: US20240191089A1)
The patent filed by 3D Systems Corp. describes composite inks for use in a 3D printing system, consisting of a carrier ink with a curable material and solid powder filler. The composite ink, in its uncured state, must have a HALT score of at least 2 when tested at 65°C for 14 days and an average loss factor tan d of 3 or less over a specific angular frequency range. The curable material can include monomeric or oligomeric materials, with specific viscosity and composition requirements outlined in the claims.
The composite ink must meet specific criteria regarding viscosity, composition, and performance, including HALT scores, loss factor, and shear viscosity. The curable material can be monomeric, oligomeric, or a combination of both, with specific weight percentages outlined. The solid powder filler must have specific particle size, aspect ratio, and surface area characteristics, with functionalized exterior surfaces in some cases. The composite ink formulation also includes a dispersant and must not behave as a Bingham fluid at a specific temperature. Additionally, a method for printing a 3D article using the composite ink is outlined, involving selectively solidifying layers of the ink to create the final product.
