Which is more potential in the future, 3D printers or medical devices?

However, the strength of domestic medical device enterprises can not be said to be weak, but there is still a big gap compared with foreign enterprises such as GE and Philips. As far as I know, the better company in China is Mindray. Neusoft Philips (this is a joint venture). And what I know is that the medical device industry is violent and profitable.
