One thing that comes to mind would be material for practice. You might need special filament to make it "realistic"?
If you're looking for a scale model of the organ system, that should exist and hopefully others know more :)
I don't think realistic texture is all that important. Most of the practice is more about the technique and maintaining sterility throughout.
Just to clarify, you don’t care about the sterility of specific part? Fdm prints in particular can’t be kept sterile.
I assume you need it to be flexible-ish at the very least, which you might achieve with TPU, but I still say mold casting is the way to go.
It wouldn't need to be sterile at all, it's just a teaching tool for patients before they are discharged home. Showing exactly where things go and why is much easier to understand when you can see it, an absolute ideal model would be a cross section.
