摘要： A system of inkjet inks suitable for additive manufacturing by inkjet printing includes a build ink and a support ink, the build ink and support ink have a differential color scheme and at least one of the build ink or the support ink includes a colorant. A method of additive manufacturing includes providing such a system of inkjet inks and printing via a multi-jet inkjet printing system an article with the build ink and the support ink, the article including a build material portion and a support material portion. A cartridge or kit for additive manufacturing by inkjet printing includes such a system of inkjet inks.

摘要： A curable ink composition for forming a three-dimensional (3D) object via a digital additive manufacturing system is provided. The composition may comprise greater than about 30 weight % of one or more oligomers, at least two monomers comprising a lowest viscosity monomer and a highest viscosity monomer, one or more photoinitiators, and optionally, one or more additives. The ratio of the weight % of the total amount of oligomers to the weight % of the total amount of monomers may be at least about 0.5 and the ratio of the weight % of the lowest viscosity monomer to the weight % of the highest viscosity monomer may be at least about 5.

摘要： A support material for use in additive manufacturing includes greater than about 30 weight percent up to about 70 weight percent of a C12 to C18 fatty alcohol ethoxylate and about 30 weight percent to about 70 weight percent of a C16 to C22 fatty alcohol, a transition temperature measured as the temperature immediately before phase change, based on viscosity measurement, is less than about 65° C. A system for additive manufacturing includes such a support material and a build material, the ratio of C12 to C18 fatty alcohol ethoxylate to C16 to C22 fatty alcohol is selected for property matching of the support material to the build material. A method of additive manufacturing includes providing such a system and printing via an inkjet printer the support material and the build material to provide a precursor to a three-dimensional printed article.
