The link I mentioned from popular mechanics is the state of molecular 3d printing. So yes the printer does exist and can do some really impressive things. However as the article states it is limited to what it can create right now. The technology sounds really interesting. However it might be a bit out of our knowledge as it doesn't seem to be widely available passed the scientific academia world.
This link here talks about reactionware for Chemical Syntheses as well as a TED talk about it
