NOVELTY - Ink composition comprises a solvent system has 50 vol.% dichloromethane, chloroform, and organic solvent having a lower vapor pressure at 23℃ than the dichloromethane, chloroform, or a mixture. The polyester polymer is soluble in the solvent system at 23℃, and solid particles are insoluble in the solvent system at 23℃. The ink composition preferably comprises 50 vol.% solid particles based on its solids content. USE - Ink composition used for forming three-dimensional objects, films and coatings. ADVANTAGE - The ink composition is used to make the first or second three-dimensional printed objects to a surface of one of the first or second three-dimensional printed objects, which enables to contact the other of the first or second three-dimensional printed objects to the applied ink composition, and further allows the solvents in the solvent system to evaporate to form the multi-portion.
