I am sorry - I think I was a bit unclear. The inner diameter of the tube needs to be about 0.5 / 1 mm big. The outer diameter can be as big as 5 mm. Do you still think that such a structure is too fine for the ultimaker?

Hey, I am a research fellow at a university clinic and want to print parts of the vascular system to analyze the flow patterns within the system. Therefore I need to generate quite small structures (tubes down to a diameter of 0.5 mm), which need to be waterproof, because the structures should be used in a flow phantom. I haven't decided yet which 3D-Printer I should get... - is this a task that the ultimaker can undertake? The structures (simple tube, helix, artery tree) need to be printed quite precise and absolutely need to be waterproof! I hope you can give me some insight! Thanks!!
