    PCB manufacturing by printing webs with a conductive material (school assignment)

    In addition to etching and milling PCBs, there is nowadays also a technique for manufacturing PCBs by printing webs with a conductive material on a carrier, this is what my teacher said but i cant find any machine that does this and offcourse im a beginner, can someone pls help me bij just give a machine that does this, only the machine name is enough for me,

    thanks in advance!!

    I think they mean this:
    https://www.voltera.io/
    but it isn't used commercially for large scale production because of the relatively slow speed and high cost of conductive ink.

    Re: PCB manufacturing by printing webs with a conductive material (school assignment)

    about 30 years ago, i worked on a project where the prime contractor built a few boards (about 25 cm by 25 cm)
    using a small gauge wire run point to point on a "sticky" substrate
    they coated it with some sort of epoxy(?) like stuff so it looked like a PWB
    they then drilled holes for all the leads of all the components and soldered in the components.

    the drilled holes cut through all the wires at a pin, exposing the wire to the pin and the solder
    worked fine

    how much do you think a pcb cost with the usage of conductive inkt?

    how much would a pcb cost with the usage of condutive inkt? do you know it?

    It looks like Voltera has a online store and the ink is $99 and it says it can print ~85 simple boards.

    They also have a "starter kit" that appears to come with ink, the printer, solder paste, and various other stuff. Looks like enough to make a small number of PCBs.
