While 3D printed electronics have been an option for 20 years, recent activities have shown processes to 3D print circuits and other electronics are moving from an interesting, niche topic.
Kenneth H. Church, PhD, began work on printed electronics in 1999 on a DARPA program. He began printing biomaterials in 2001 on another DARPA program. His team developed the first commercial bioprinter and went on the market in 2002. He is a pioneer in 3D-printed electronics and printed circuit structures. Dr. Church has authored and presented over 50 publications/technical presentations and more than a dozen patents or patents pending.
