The disclosure describes a polymerizable liquid that includes a reactive oligomer and a reactive monomer. The polymerizable liquid is an energy polymerizable liquid hardenable by a single reaction mechanism forming a Photoplastic material. The disclosure further describes a method of producing the Photoplastic material and articles that can be made from the Photoplastic material.

A radiation-curable ink is provided and includes: a first liquid phase, including a radiation-curable hydrophobic polymerizable compound; and a second liquid phase, including at least one compound selected from a group consisting of water, an aqueous polymerizable compound, an aqueous polymer, and an aqueous non-polymerizable compound. The second liquid phase is emulsified and dispersed in the first liquid phase. And, a three-dimensional object is formed by curing the radiation-curable ink, in which a third liquid phase derived from the second liquid phase and including at least one compound selected from the group consisting of water, the aqueous polymerizable compound, the aqueous polymer, and the aqueous non-polymerizable compound is dispersed as a sea-island structure in a continuous phase of a hydrophobic cured product formed by curing the first liquid phase. A water content of the third liquid phase is 1% by weight or more.

This disclosure describes three-dimensional printing kits, methods, and systems for three-dimensional printing with scent additives. In one example, a three-dimensional printing kit can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer particles and a scent additive. The scent additive can be chemically stable at a melting point temperature of the polymer particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.

A white ink composition can include an aqueous ink vehicle including water and organic co-solvent, from 5 wt % to 30 wt % white metal oxide pigment, from 0.05 wt % to 1 wt % block copolymer dispersant adsorbed on a surface of the white metal oxide, and from 2 wt % to 30 wt % polyurethane binder. The block copolymer dispersant can have a weight average molecular weight from 5,000 Mw to 20,000 Mw and an acid number from 0 mg KOH/g to 40 mg KOH/g based on dry weight of the block copolymer dispersant.
