A method of manufacturing an embossing element for decorative surfaces includes the steps of: a) UV curable inkjet printing a decorative pattern on a metallic surface; and b) forming a relief by etching metal from the metallic surface.

Silkworm silk, has been processed into a variety of new material formats including, hydrogels, ultrathin films, thick films, conformal coatings, 3D porous or solid matrices, fibers and many related material formats. Silk is processed in an all water-based, room temperature, neutral pH environment, is mechanically stable, edible, and biocompatible. Given the favorable material properties, the use of silk-based inks have been used in a variety of controlled chemical and biological material fabrication on the micro- and nano-scale. Tuning of the properties of silk-based inks has led to the utilization of more diverse printing techniques and has expanded the scale and function of the printed substrates.

A system for applying a coating composition is provided herein. The system includes a first high transfer efficiency applicator defining a first nozzle orifice and a second high transfer efficiency applicator defining a second nozzle orifice. The system further includes a reservoir. The system further includes a substrate defining a first target area and a second target area. The first high transfer efficiency applicator and the second high transfer efficiency applicator are configured to receive the coating composition from the reservoir and configured to expel the coating composition through the first nozzle orifice to the first target area of the substrate and to expel the coating composition through the second nozzle orifice to the second target area of the substrate.

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 thermochromic additive. The thermochromic additive can be chemically stable at a melting point temperature of the polymer particles, and the thermochromic additive can exhibit a color change at a color transition temperature that is below the melting point 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.
