4D printing and molecular assembler

How long before 4D printing and molecular assembler take of? Would you say 10 or 15 years out?

What are they using 4D printing and molecular assembler now?

I can't seem to get much information on this.The only thing I can find is this.

Let’s start with that last one. Skylar Tibbits, a lecturer in MIT’s
architecture department and founder of its new Self-Assembly lab,
describes what he’s doing as 4D printing.

If the fourth dimension is time, Tibbits’s projects are designed to
respond to energy and change over time. At TED, he showed off a
collaboration with Stratasys and Autodesk to create strands made of
multiple types of materials that when dipped in water fold themselves
into pre-designed shapes.

What would 4D printing be used for?

Team of scientists in Toronto Canada are doing that now.
