Claim 11:
12. A method of manufacturing a device for generating bubbles or droplets, the method comprising:
providing a device including a cavity having a first pressurized phase, at least one input capillary of a second phase, and an output capillary coaxially aligned with the at least one input capillary; and
producing a nozzle of a tip of the at least one input capillary by micromachining or 3D microprinting;
wherein an opening of a tip of the at least one input capillary has an internal diameter of less than half the internal diameter of the output capillary, and wherein all dimensions of the cavity are larger than 3 mm, and the output capillary has a hydraulic diameter smaller than 500 μm.
