Abstract: Filament comprising a polymeric material that includes a diacid component comprising from about 40 to 60 mole % of units derived from terephthalic acid and from about 40 to 60 mole % of units derived from a diacid chosen from isophthalic acid, a cyclohexanedicarboxylic acid, a naphthalenedicarboxylic acid, a stilbenedicarboxylic acid, or a combination thereof; a glycol component comprising at least 75 mole % of units derived from cyclohexanedimethanol; wherein the polymeric material has an inherent viscosity loss of 3% or less after being extruded; and method of using this filament in production of different articles by 3D printing are disclosed.

Abstract: This invention relates to a filament build material for a three-dimensional printer, where the filament comprises a polymeric material that includes units of a diacid component and units of a glycol component. The units of the diacid component includes from about 40 mole % to about 60 mole % of units derived from a first diacid and from about 40 mole % to about 60 mole % of units derived from a second diacid, wherein the first diacid is terephthalic acid and the second diacid is chosen from isophthalic acid, a cyclohexanedicarboxylic acid, a naphthalenedicarboxylic acid, a stilbenedicarboxylic acid, or a combination thereof.

Abstract: This invention relates to an object comprised of a plurality of fused filaments of a polyester material that includes units of a diacid component and units of a glycol component. The co-polyester has a zero shear viscosity no greater than about 3000, an elongation at break of at least about 75%, a density no greater than about 1.25 g/cm3, a glass transition temperature of at least about 80° C., an inherent viscosity from about 0.55 dL/g to about 0.7 dig, a density no greater than about 1.25 g/cm3, and a crystallization half-time no greater than about 300 minutes.

Abstract: Objects can be produced using an additive manufacturing process and the objects can be removed from the substrates on which the objects are formed. An object can include a plurality of layers of a polymeric material that includes units of a diacid component and units of a glycol component. A process can be used to form the object that includes depositing a plurality of layers of the polymeric material onto a substrate to form the object. In some cases, the plurality of layers are deposited onto the substrate according to a predetermined design.
