The design of an esophageal stent is optimised using finite element analysis (FEM). The proposed design has been optimized in order to be manufactured by Fused Deposition Modelling (FDM) so that it can be easily customised to the patient. TPU is an elastomer that sometimes proposes some difficulties to be printed especially in relation to retraction, to avoid this kind of movements the stent has been specially designed to be printed in vase mode.
