Problems solved by technology
Although inkjet printing offers a relatively versatile and inexpensive process for applying a material to a substrate, ink jet printing is generally limited to placing exceedingly thin layers of ink on paper or cloth which are essentially two-dimensional.
This limited range of viscosity in turn limits the variety of materials which may be deposited.
As a result, mechanical connections may not be made to layer built using a photolithographic layer.
The limitations to Fodel® are: 1) The Fodel® process is purely planar.
No three-dimensional features can be produced.
4) The material costs of the Fodel® process are relatively high.
5) The Fodel® process is limited to features larger than 50 microns.

Embodiment Construction
I. Direct Write™ Methods & Apparatus
[0045]FIG. 1 presents a a schematic view of one of the preferred embodiments of the Direct Write™ System, which comprises methods and apparatus for maskless, mesoscale deposition of a source material on a substrate. Unlike many previous deposition systems which are restricted to the formation of planar layers on a flat substrate, the present invention is capable of forming a wide variety of planar, non-planar, conformal or three-dimensional features on a substrate having virtually any profile or topography.
[0046] In one embodiment, the invention comprises a source of material 10 contained by an enclosure 11. Although the a preferred embodiment generally includes a source material in liquid form, the source may comprise any aggregation, mixture, suspension or other combination of any materials in any physical phase. The source of material 10 is contained in a vessel, pool, volume or chamber which is coupled to or in communication with an atomizer ...
