Abstract: A system for forming a product with different size particles is disclosed. The system comprises at least one print head region configured to retain a first group of print heads configurable to additively print at least a first portion of the product with a first material and a second group of print heads configurable to additively print at least a second portion of the product with a second material. The described system may also comprise a processor configured to regulate the first group of print heads and the second group of print heads to distribute the first material and the second material. A method of making an object by ink jet printing using the disclosed system is also disclosed.

Abstract: Ti ink compositions for printing, such as ink jet printing, are disclosed. The ink compositions comprise a liquid dispersion of Ti hydride powder having a mean particle size of less than 10.0 microns; a liquid carrier; and at least one surfactant. Methods of making and using the disclosed inks are also disclosed. For example, a finished Ti product can be produced by printing the disclosed ink composition, such as by ink jet printing, to form a green article, heating the green article to dehydrogenate it and form a Ti containing part. The method may further comprise sintering the Ti containing part to produce a sintered Ti product. In an embodiment, the method comprises printing one or more support materials for the ink composition, that comprises solid particles of a metal oxide, a metal carbide, a metal nitride, a polymer, or combinations thereof.

Abstract: 3D (three-dimensional) ink-jet printing includes techniques for evaporating a carrier liquid during printing while at least a portion of dispersant remains in the printed layer; evaporating dispersant in a first layer prior to sintering the first layer and/or prior to printing a second layer; leveling an upper-layer of a printed object using a horizontal roller; and printing layers of an object, each layer with both object and support portions, resulting in an object with support, in particular, support for negative angles and molds.

Abstract: Herein is disclosed a method for electrostatic printing. The method may comprise: a. electrostatically printing a discontinuous layer of a transparent electrostatic ink in a first area on a print substrate; b. electrostatically printing an image comprising a coloured electrostatic ink on the print substrate in a second area, which may or may not be in the same location as the first area, wherein the electrostatic printing in each of steps a and b involves, respectively, transferring the transparent electrostatic ink or the coloured electrostatic ink from a photoimaging plate to the print substrate via an intermediate transfer member. The method may then involve repeating steps a and b on the same or different print substrates, wherein each repeat of step b results in the same or a different printed image, and the discontinuous layer of transparent electrostatic ink varies between at least two different printing patterns. A system is also disclosed herein.
