The invention relates to an additive manufacturing process (3D printing) using particles having a meltable polymer. The meltable polymer comprises a thermoplastic polyurethane polymer which has a flowing temperature (intersection of E′ and E″ in the DMA) of ≥80° C. to <180° C. and a Shore A hardness according to DIN ISO 7619-1 of ≥50 Shore A and <85 Shore A and which, at a temperature T, has a melt volume rate (melt volume rate (MVR)) according to ISO 1133 of ≥5 to <15 cm3/10 min. The invention also relates to an item which can be obtained by means of the method. |
