Boeing Patents New 3D Printing Technique

Boeing (NYSE:SA) has patented a new 3D printing technology that prints objects while they are floating in midair.
According to an article on 3D Printing Industry:

This technology is like one I’ve never personally seen before, utilizing multiple 3D printers at once to extrude material with diamagnetic properties. Instead of using a build plate, Boeing’s technology creates magnetic fields that hold the first bit of 3D printed material (called the ‘nugget’ by Boeing) in place, which is then built upon by the multiple 3D printers involved in the process.
Boeing explained the need for this type of process within their recently published patent: “There is a need for an AM method and apparatus that eliminates the need for a platform and/or support materials to stabilize the part during the fabrication process, and which removes limitations on the types of features that can be formed, allowing full body 3D printing of complex parts.”
