AI Technical Summary

Benefits of technology

"The Direct Write™ System is a new device that can deposit small, atomized particles onto a substrate with high accuracy. It can create planar, conformal, or three-dimensional surfaces and can handle a wide variety of materials, including metals, alloys, dielectrics, insulators, and organic and biological entities like enzymes, proteins, and viruses. The device also includes a virtual or cascade impactor to remove selected particles from a stream of gas to enhance deposition. Overall, the Direct Write™ System offers a new and effective way to deposit materials onto surfaces with high precision."

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.
