So, I am sure that this thread has been seen by many of you very many times. However, I am trying to put a new spin on the whole new guy just joined our forum and has no idea what anything is kind of thread. So, to give you an idea of what I do and am.. I am a graduate student at a university and we develop methods to track small radioactive particles in fluid flows. Thus, giving us an idea of what the flow structure is like, the flow rate and many other interesting things. So, for us, it would be really cool if we could 3d print out interesting objects and analyze how fluid flow flows around or inside of them.

One of the things we are looking into doing is seeing if we can track the particles inside of a simulated human artery and thus possibly identify blockages and the such. Or perhaps, we could design a fluid mixer in CAD and then print it out and see how well it works. So, this brings me to my question. I need a 3d printer which can print out small, but realistic sections of simulated arteries, some of which can have blockages modeled inside of them. The artery needs to be durable and not leak. Ideally, we would need to be able to 3d print threads on the ends of the arteries for hooking up small pipes or tubes onto them for the simulated blood flow.

Is this doable with 3d printing? If so, what kind of printer should I be looking at? What kind of information could I provide you that would help you help me out?

Thanks!
