How Close Are We to 3D Printing Humanoid Robots?

With every step we advance in the fields of robotics and artificial intelligence (AI), it seems we can't help but ask, "Is this something that will bring us closer to'Westworld?'" Since it premiered last year, HBO's hit sci-fi series has become the mainstream benchmark for AI systems. In the show's fictional world, robots can think and function like humans, and they are nearly indistinguishable from their human counterparts. It has created this sense of wonder at what's possible given today's quickly advancing technology. However, it has also reinforced how very far we still have to go before we can create AIs with the same level of sophistication. Taken at face value, we know "Westworld" hosts are incredibly advanced AIs that probably have some sort of deep learning mechanism that allows them to quickly respond to their environments.
