Application of a 3D-printed ”fistula stent” in plugging enteroatmospheric fistula with open abdomen: A case report

Figure 2 Manufacturing process of the “fistula stent”. A: The blueprint of “fistula stent” was built with Solidwork software and saved in Standard Template Library (STL) form; B: Fused Deposition Modeling is a process where thermoplastic filaments are driven with a motorized heated nozzle; C: Build model of a hollow and curving pipe stent with a small protuberance and integrated wall; D: Flexibility of the “fistula stent”; E: Shape memory of the “fistula stent” after application of an external force.
