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: 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.
