As part of a NEDO project, Osaka University has developed the world's first 3D printer that is able to additively fabricate from pure copper by using a high-intensity blue laser diode. As a result, it is now possible to complete additive manufacturing of pure copper, which has high electrical conductivity and high thermal conductivity and thus was previously difficult to melt using a conventional laser. It is expected that this breakthrough will have applications for processed parts which are necessary in industries such as aviation, space, and electric vehicles.

The technology is scheduled to be revealed at the "The International Congress on Applications of Lasers & Electro-Optics (ICALEO)," which will be held from October 22 to 26, 2017 in Atlanta in the United States. It will also be displayed at the international exhibition "Photonics West 2018," which will be held from January 30 to February 1, 2018 in San Francisco in the United States.
