In 1999, Optomec, which had already begun commercializing directed energy deposition technology from Sandia National Laboratories, was awarded a $9 million contract from the Defense Advanced Research Projects Agency (DARPA) to develop a method for depositing a range of materials onto virtually any substrate, using a process known as “direct writing” . This resulted in the Aerosol Jet Printing (AJP) process, which involves the atomization of a given material into a mist before that mist is focused and deposited using an inert gas, spraying it through a thin nozzle onto a substrate.
