How someone answers the question may depend on where they put the boundaries. This is twenty year old technology, and has gone from $200,000 machines to $500 machines, which use stronger and more varied materials. So that part has followed Moore's law pretty well so far.

While the home based cheap machine market may not accelerate from now on like it has, research is ongoing into the technologies. The ultimate goal is atomically precise manufacturing, and we still have a log way to go to be able to perform that.

And if we look at the effect that the technology has on the manufacturing industry and commerce, we are just getting started and will see many leaps in productivity and cost effectiveness.
