Abstract: 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.

Abstract: 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.

Abstract: An ink for use in 3D printing including at least one monomer, and an optional oligomer, and a photoinitiator, and the ink has a high glass transition temperature (Tg) and wide range of viscosity. The 3D ink composition, and embodiments, maintains a homogeneous and easily processed consistency when used in a multi-jet modeling printing process.
