What is Cool About Additive Manufacturing? PTO Event Today Shows the Latest for This Economic Engine

24 January 2013 Cleantech & Nano Publication

I attended today the USPTO partnership meeting on “additive manufacturing” (aka 3D Printing). The content was excellent, covering both talks and demonstrations. Companies presenting included 3D Systems, Stratasys, Shapeways, MakerBot, Ex One, and EOS. Several hundred persons attended, including in person and via the web, and the room energy was excellent throughout the three hours plus of content. The 3D printing revolution appears to be on after some 25 years of gestation. 

Ex One is featured here.

The USPTO should be congratulated for putting together this informative, exciting event. The USPTO did not give too much overview of how patenting impacts this, but patenting was frequently noted by the speakers, and the PTO did note that there have been around 6,800 patent applications filed in this area over the past ten years. I was particularly struck by the concept that 3D printing can in some cases make objects which cannot be made by other ways. I would also like to hear more about nanoscale aspects of this including materials, interfaces, and nanoscale resolution. One of the driving forces for nanotechnology and nanomanufacturing is additive manufacturing. This recently published U.S. patent application from Lockheed Martin (2013/0018243) shows use of carbon nanotubes and uses the phrase “bio-additive manufacturing.” We will continue to monitor patent filings in this important area as 2013 progresses. 

In 3D printing, an object is built up layer-by-layer under computer controlled manufacturing. The talks today covered the historical development including the original stereolithography, laser sintering, binder-on-powder printing, and inkjet 3D printing. Today, some of the companies are trying to “democratize” the technology and introduce this wonder to the general public. With 3D printing, everyone can become a creator. Recently media reports on 3D printing have been abundant. Hopefully, venture capital will be interested. Stay tuned!
