1. A method of synthesizing or depositing a biopolymer on a substrate using a dispensing head with biopolymer or biomonomer fluids, the fluid dispensing head having:

  • a reservoir chamber;

    multiple jets which can dispense droplets of biopolymer or biomonomer fluids onto a substrate, each jet including a delivery chamber communicating with the reservoir chamber, and including an orifice and an ejector which, when activated, causes a droplet to be ejected from the orifice;

    the method comprising;

    (a) positioning the head with the orifices facing the substrate;

    (b) dispensing at least one droplet from an orifice of said orifices on the substrate;
