Microfluidic channels

This is a simple test I ran on my Form 2 printer to see if it was possible to print a micro/millifluidic system. I wanted to try out several geometries to see if a) they could be printed and b) if they offered any advantage. I'm particularly interested in a channel with a twisted 3 dimensional structure, that simulates natural capillaries, is beneficial when moving cells around the system.
I'm happy to state that at least the first stage worked and all channels could be printed, cleaned out, and allow liquid to flow through them. Cell studies will have to wait until later.
