摘要： A solubilizing agent and a compound made by reacting selected nucleophiles, including fatty acid reactants and amines with an isocyanate are disclosed. The addition of the isocyanate and the different nucleophiles will create a di-urethane tetra-amide solubilizing agent product. The polyamide-solubilizing agent is useful as an ingredient in a phase change solid imaging material and as carrier compositions used to make phase change ink jet inks.

摘要： Phase change compositions that are solid at ambient temperature and liquid at an elevated temperature above ambient temperature are disclosed for advantageous use in selective deposition modeling methods for building three-dimensional objects. A phase change composition according to the disclosed invention is a semi-crystalline component mixture having a freezing point of at least about 68.degree. C., a melting point of at least about 88.degree. C. and a viscosity of about 13 centipoise at 135.degree. C. The composition includes a plurality of waxes having a broad melting point range and molecular weight range. Three-dimensional objects having minimal curl, delamination and stress cracks can be produced at a faster rate than heretofore known by using selective deposition modeling techniques employing the disclosed compositions.

摘要： A method, system and apparatus for forming a three-dimensional object on a layer-by-layer basis involves forming a portion of the three-dimensional object using selective deposition modeling (SDM). SDM involves using at least one orifice, such as a jet, which dispenses a droplet of a flowable material that solidifies upon being dispensed. A drop volume capability of each orifice is adjusted until substantially all orifices have a uniform drop volume capability and all dispensed droplets of the flowable material have a uniform volume.
