A method for improving z-axis strength of a 3D printed object is disclosed. For example, the method includes printing a three-dimensional (3D) object with a polymer and magnetic particles, heating the 3D object to a temperature at approximately a melting temperature of the polymer, and applying a magnetic field to the 3D object to locally move the magnetic particles in the polymer to generate heat and fuse the polymer around the magnetic particles to improve a z-axis strength of the 3D object.

Utilization of magnetic particles to improve z-axis strength of 3D printed objects

According to various embodiments, there is provided a toner composition and a developer. The toner composition includes toner particles including a resin, a colorant; and a surface additive applied to a surface of the toner particles. The surface additive includes polyaniline doped strontium titanate (SrTiO).

Toner surface additive

According to various embodiments, there is provided a toner composition and a developer. The toner composition includes toner particles including a resin, a colorant, a charge control agent, and a surface additive applied to a surface of the toner particles. The surface additive includes strontium titanate (SrTiO), silica (SiO), silicon tetrachloride (SiCl) and a charge control agent.

A low melt toner includes a core having a core polystyrene-butyl acrylate resin, a crystalline polyester resin, a pigment present in an amount from about 7% to about 20% by weight of the low melt toner, and a paraffin wax; a ratio of the polystyrene-butyl acrylate resin to crystalline polyester resin is in a range from about 5:1 to about 7:1; and a shell disposed over the core including a shell polystyrene-butyl acrylate resin.

Hyperpigmented low melt toner

A method of synthesizing a branched polyester resin. Particularly, the method includes an alkoxylation reaction that includes reacting a monomer bisphenol A with a cyclic alkylene carbonate.

Method of making branched polyester resin

The present disclosure describes toner particles that have polyester resin and styrene/acrylate resin in the core.

Styrene/acrylate and polyester hybrid toner

A process for making a latex emulsion where distillation occurs at an elevated temperature is used to make resin particles with a conditioned surface which can be used to make magenta toner with increased efficiency.

Magenta toner

The disclosure describes a pigment of certain surface area for use in toner.

Colored toners

A toner includes a core including a homogenized mixture of a first polyester latex, a styrene/acrylate latex, and a compatibilizing agent latex that includes a graft polyester-styrene/acrylate copolymer and a shell that includes a polyester latex. A process includes (1) homogenizing a mixture to form a plurality of core particles, the mixture including a first polyester latex, a styrene/acrylate latex, and a compatibilizing agent latex comprising a graft polyester-styrene/acrylate copolymer and (2) adding a shell polyester latex to the plurality of core particles to form a plurality of core-shell structures.

Emulsion aggregation toner comprising hybrid latex

Unsaturated polyester resins and processes for making the same are disclosed herein. In particular, the process for making the resin provides resins with improved properties. The unsaturated polyester resins have substantially reduced free fumaric acid as compared to that made from conventional processes. The toner resins are used to prepare toner compositions that have improved performance.

Toner resins and processes for making the same

Amorphous polyester resins and processes for making the same are disclosed herein. In particular, the process for making the resin provides resins with improved properties. The amorphous polyester resins have substantially reduced free fumaric acid as compared to that made from conventional processes. The toner resins are used to prepare toner compositions the have improved performance.

A method of forming toner particles includes aggregating a mixture of a latex, a wax, and an optional pigment to form pre-toner particles, and coalescing the pre-toner particles at a substantially constant target temperature selected within a range from about the glass transition temperature of the pre-toner particles to about 75&#xb0; C., thereby creating toner particles having a substantially constant particle size distribution during the coalescing step.

Toner process comprising reduced coalescence temperature

The present disclosure provides emulsion aggregation (EA) toner particles having less pigment on the particle surface and a more uniform pigment distribution. The process of preparing the toner includes specific mixing speeds and use of specific temperatures during the emulsion aggregation process and the addition of a shell to the toner particles.

Emulsion aggregation process

Processes for producing toner are provided which utilize reactive coalescing agents in forming the toner particles, as well as toners produced by such processes.
