Where is the future of 3D Printing heading?

   Many of you might've not even heard of 3D printing, if this is the first time it most definitely won't be the last. 3D printing will be tangible for people in their own homes most likely in 2020, weird right? Print a coat hanger, a plate, maybe even dinner, things grow and advance technically daily and the things that you can print will continue to amaze you.

    So where is the technology headed into the future you ask, well I believe it won't necessarily replace factories producing small gadgets that are very quick to produce but to more technical and expensive items. A NASA rocket powered engine was made in a third of the time and a large chunk of change was saved using the 3D printer. If a rocket engine was produced you can only fathom the types of things that can be made. Therefore the future of 3D printing has a glamorous future.
