Use of a thermoplastic polyester for producing a 3D print, said polyester comprising at least one 1,4: 3,6-dianhydrohexitol unit (A), 1,4: 3,6- It contains at least one alicyclic diol unit (B) other than dianhydrohexitol unit (A), at least one terephthalic acid unit (C), and has a ratio (A) / [(A) + (B) ] Is greater than 0.05 and less than 0.75, and the polyester does not contain acyclic aliphatic diol units or has a molar amount of acyclic fat of less than 5% based on the total monomer units of the polyester. A reduced viscosity in solution (25 ° C .; phenol (50% by weight): ortho-dichlorobenzene (50% by weight); polyester 5 g / L), containing a group diol unit, used greater than 50 mL / g. |
