1. A method for producing a stent graft, which comprises the following steps:
providing a graft made of a first polymer-based material; and
then applying a stent structure comprising a plurality of struts made of a second polymer-based material onto the graft by means of an additive method;
wherein the graft and the applied stent structure are configured such that the stent graft is arrangeable in at least one compressed state and in at least one expanded state, wherein the stent graft has a smaller cross-section in the at least one compressed state than in the at least one expanded state.
