Abstract: A sustainable material suitable for three-dimensional printing is disclosed. The sustainable material comprises a resin derived from a bio-based diacid monomer and a bio-based glycol monomer. The resulting sustainable material provides a much more robust 3-D printing material with different properties than conventional materials.

Abstract: Incorporation of organic amines as neutralization agents in based phase inversion emulsification (PIE) processes to provide emulsification of high molecular amorphous and high molecular branch amorphous polyester resins, which are traditionally difficult to emulsify. The organic amines facilitate emulsification of these resins to achieve desired particle size with a narrow size distribution.

Abstract: A system for pigment milling includes a pulsing direct current (DC) source that generates a DC pulse, an electromagnetic field generating subunit that includes an electromagnetic coil coupled to the pulsing DC source to receive the DC pulse and to generate a magnetic field, and a rotating container subunit that includes a container for holding magnetic particles and ink pigment particles in an ink carrier, and a rotating subunit to rotate the container. A portion of the container is disposed within the electromagnetic coil and generation of the magnetic field causing motion of the magnetic particles thereby dispersing the ink pigment particles within the ink carrier.
