Harris, D. M., Liu, T., & Bush, J. W. (2015). A low-cost, precise piezoelectric droplet-on-demand generator. Experiments in Fluids, 56(4), 1-7.
We present the design of a piezoelectric droplet-on-demand generator capable of producing droplets of highly repeatable size ranging from 0.5 to 1.4 mm in diameter. The generator is low cost and simple to fabricate. We demonstrate the manner in which droplet diameter can be controlled through variation of the piezoelectric driving waveform parameters, outlet pressure, and nozzle diameter.

Hi,
I was trying to replicate the drop-on-demand-stream of regular inkjet printer cartridge, but I was unable to generate drops smaller than 1.8-2mm using my diy setup.
could you share some details about the process and required-setup to generate drops at scale of 0.5 mm dia? also any tip to reduce it further.
I am fairly comfortable with coding parts,but not much good with hardware, kindly share your thoughts and details.

I have built aa droplet generator on the same principle (a cavity holding liquid and a piezo), using a 3D printer nozzle as the liquid output. …unfortunately the plans are not public
