3D printing of aluminum is extremely remarkable because there are a lot of industries that can benefit from the ability to make a one-off part that is of high strength and perhaps is conductive. One example is the auto-collision body repair industry. If body panels can be printed, there will be no need to keep extra replacement panels in storage. Manufacturers can come out with new designs more frequently to better compete and to catch up with a changing market.
Prof. Chung has patented a more efficient design application of 3D metal printing process that is more cost effective in production of parts.
I have known Deborah Chung since the late 1970s when I was on faculty at
the University of Pittsburgh. (I retired in 2011.) Professor Chung was
on faculty in Materials Science at Carnegie Mellon University at the
time. She was at the forefront of carbon science and continues to be
Deborah has always been honorable and strong in character, faithful to her religion, excellent in her profession and respected by her compatriots. She is also an excellent pianist, with a voice to match.
I am proud to have her as a friend and colleague.

3D printing is hot in current market, but 3D metal printing is still difficult. I am excited Professor Chung has proposed such practical method with creative idea of thixotropic metal and non-mold manufacture for large scale metal structure. I bet it will be one of the most exciting and revolutionary invention in the filed of materials and manufacture in 21st century, just because it will substantiately change the making way of metal structure until now.
This invention is revolutionary by using molten metal liquid phase powder processing method. The shear thinning effect (thixotrophic) in the molten liquid powder mixture makes it possible to form metal matrix composite at much lower processing temperature. This technology can not only used to form metal matrix composites, but also ceramic reinforced metal matrix composites. Due to the low processing temperature, it is a low cost high productivity process. This is a significant technology breakthrough with unlimited business opportunity.
Practical 3D metal printing is an amazing invention by Prof. Chung. This will surely be widely accepted throughout the world.
The thixotropic approach of metal 3-D printing invented by Deborah Chung of Practical 3D Metal Printing is revolutionary. This will open up new ways to manufacture large and small metallic objects in many industries such as auto, aerospace, appliance, and many others.
