Next year, 3-D printers may finally make something you want to keep
What current home 3-D printing technolgoy produces, largely, is tchotchkes. Fun around the house, and good for getting an idea of what a 3-D design will look like in real life, but not a strong product like ceramic or metal. That said, laser sintering technology — which layers powdered metal, glass, or ceramic dropped below melting point to build models and molds — allows for the kind of finished products the masses are craving.
