  • Patent number: 11383435
    Abstract: In an example of a method for three-dimensional (3D) printing, a build material composition is applied to form a build material layer. The build material composition includes a polyamide. The polyamide is selectively melted, based on a 3D object model, in at least a portion of the build material layer to form a molten portion including molten polyamide. An epoxy agent is selectively applied, based on the 3D object model, on the molten portion of the build material layer. The epoxy agent includes a polyfunctional epoxy, which crosslinks the molten polyamide in the molten portion.

    Abstract: There is disclosed a liquid gel composition useful for incorporation in thermoplastic and thermosetting resins. The liquid gel comprises a liquid mixture of certain hydroxyalkyl fatty amines or fatty imidazolium quaternaries which is gelled by an organophilic, expanding lattice clay that is ion exchanged with alkyl ammonium ions. The clay is employed at a sufficient concentration to form a stable gel and is milled into the liquid vehicle to form a gel of a suitable viscosity to permit it to be added to the resin with metering injection equipment. The composition when used at low concentrations in resins enhances the physical properties of the resins by imparting a permanent anti-static characteristic to the resins and by significantly decreasing their brittleness, thereby increasing elongation, impact and tensile strengths of the resins.
