Can a small erosion resistant nozzle be made?

[matrix1781 0]

I ma looking for a nozzle of 0.8mm length and 1 mm diameter. Using conventional manufacturing methods, it is difficult to make this nozzle. Does 3D printing allow for this nozzle to be made? This has to be made out of polyurethane or any other erosion resistant material. Any advice welcome

I would not use a FDM printer for that, the parts are simply too small.

Is 1mm the outside diameter or the inside diameter? Inside diameter of 1mm is easy. You can with practice get it perfectly repeatable. Outside diameter of 1mm would be hard to do. Also what do you mean buy erosion resistant? typical 3d printing materials can withstand erosion by water only but add sand or almost any solid into the mix and I don't know of any 3d printed materials that can handle it. It's just plastic.
