Combining different deposition technologies to manufacture items with multiple materials has been possible for quite some time. The problem is mostly with the patent system in the west. It's a patent minefield of obvious claims by patent holders that aren't even using the tech or are not interested in anything other than prototyping at slow print rates with very high profit margins on the materials. I expect an explosion of the tech in China or after a few more of the patents expire in the west.
