Chinese Patent Application- Interesting twist on EBM Development
Jeff Immelt General Electric Company - Chairman & CEO in EDITED TRANSCRIPT - General Electric Co Annual Outlook Investor Meeting - DECEMBER 14, 2016 - "There is 15 parts in production right now. David Joyce is kind of running this play for us. Our goal is to have 500 parts in production by 2020. This is a lot. This would make us, by far, the biggest in the world. We have got tiger teams in each business that are kind of assigned to get these parts underway. We have got multiple used cases and tremendous opportunities as it pertains to driving additive inside GE."
Here's one for GE's IP protection tiger team. The patent application has a machine design that includes a cutting tool. It's hard for me to tell from the text if the heat present in the build chamber is a good thing or not.
From the application - "[0004] In the prior art, an electron beam melting and cutting composite technology is adopted to combine the metal melting with cutting machining. The electron beam melting and cutting composite technology uses a high-power electron beam gun to directly melt the metal powder material in a vacuum chamber, and a component having any complicated structure and properties similar to a forging is directly formed via a 3D model without adhesives. Besides, by performing a printing operation and a cutting operation at the same time, a surface figure accuracy of the finally formed structural component can directly meet the usage requirements."
United States Patent Application 20170050261 A1 - ELECTRON BEAM MELTING AND CUTTING COMPOSITE 3D PRINTING APPARATUS - February 23, 2017
It's also been filed at the World Intellectual Property Organization - (WO2016154931) COMPOUND 3D PRINTING DEVICE FOR ELECTRON BEAM MELTING AND CUTTING
Also interesting is that the World Intellectual Property Organization makes an application document history available. A noob find.
