3D Printing breaking the barriers into replication of real objects

3D Printing is a nother way of saying science has broken the barriers into replicating real objects with very high precision measured in microns (less than human hair thickness).  

Wow !   This is really something.  See how it also extends the capability to moving parts and functionality of the original object transferred into the replicated objects.

Just look into near-future possibilities with this technology, specially when it gets commercialized

• Production of replicas of tools and machines
• Production of low-cost spares specially when  they are needed in a hurry in emergency situations
• Use of other materials to create the replicas including metals like gold, silver, aluminum, ... etc
• The coloring option opens new horizons for replicas with artificial colors that you cannot find in nature.
• Possibility of producing larger or smaller (to scale) replicas of objects we find in real life.
• Combining this technology, the scanning part of it least with static and dynamic holograms to produce things that can be captured and projected as 3D holograms into physical 3D objects.    
• Possible use of this technology and others to produce human-like intelligent machines (robots)

Just to get more on this amazing technology, I  am adding few more links for your view
