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.
