Is 3D printing technology useful for common people
I need to prepare a document on 3D printing technology. Can someone please elaborate on what is 3D printing technology? I have absolutely no idea on this, so I need to know the basics like what type of machines print 3D objects and what materials do they use to print it. How is the look and feel of the same? Is this technology very costly to be afforded? How much space does a 3D printer requires?
