The invention relates to the use of a thermoplastic polyester for producing a 3D-printed object, said polyester comprising: at least one 1,4:3,6-dianhydrohexitol unit (A), at least one ethylene glycol unit (B); at least one terephthalic acid unit (C); wherein the ratio (A)/[(A)+(B)] is at least 0.01 and at most 0.60, said polyester being free of alicyclic diol units or comprising a molar amount of alicyclic diol units, relative to the total of monomeric units in the polyester, of less than 5%, and having a reduced viscosity in solution (35°C; orthochlorophenol; 5 g/L polyester) greater than 40 mL/g. |
