1. A method of fabricating a three dimensional article, said method comprising:

  • providing an article fabrication system comprising;

    a plurality of material deposition tools containing one or more materials useful in fabricating the article;

    a material deposition device having a tool interface for receiving said material deposition tools, the tool interface of said material deposition device being movable in various paths, including curvilinear and/or non-planar paths, relative to a substrate to dispense material from the material deposition tools to the substrate, wherein all of the plurality of material deposition tools have an orifice through which material is deposited where the orifice is of a size less than the substrate'"'"'s width;

    a system controller operably connected to said material deposition device to control operation of said material deposition device; and

    a tool rack comprising tool mounts, wherein the tool rack is suitable for holding the plurality of material deposition tools or components thereof on said tool mounts anddispensing material from said material deposition tools taken from tool rack and mounted on the tool interface of said material deposition device, in amounts and at positions on the substrate in response to instructions from said system controller, whereby a three dimensional article is fabricated on the substrate.
