I always love seeing new 3D printing patent applications. There has been some wacky-looking stuff presented — Samsung’s recently granted patent for a holographic 3D printer comes to mind — but I’ve never seen anything like the technology Boeing has come up with. The aerospace giant has recently filed a patent application for a process that 3D prints levitating objects. Yes, levitating objects.
It seems ludicrous. Multiple 3D printer heads shoot material at a magical floating nugget that collects the material, layer by layer, and grows into, apparently, an airplane part. I can’t wrap my head around it, but Boeing is very serious. The proposed technology is called “Free-Form Spatial 3-D Printing Using Part Levitation,” and it involves a “nugget” (yes, that is in fact the scientific term) made of printed material that is suspended in space via magnetic fields. Several printer heads surround said nugget and deposit additional printing material onto it from all sides.
