Abstract: Thermoplastic moulding composition for 3D printing containing a polymer mixture A made of components a and b: a being from 30 to 95% by weight of at least one vinylaromatic copolymer a with average molar mass Mw from 150 000 to 360 000 g/mol, b being from 5 to 70% by weight of at least one impact modifier b, where the viscosity of the moulding composition (measured in accordance with ISO 11443) at shear rates of from 1 to 10 l/sec and at a temperature of 250° C. is not higher than 1×105 Pa*s and the Melt Volume Rate (MVR, measured in accordance with ISO 1133 for 220° C. and 10 kg load) is more than 6 ml/10 min.
