Professor Plastic: A Desktop 3-D Printer in Every Home? – Plastics Make It Possible

Some examples, all made possible by plastics:

• A dad creates unique toy trains and tracks for his kids while another creates a jigsaw puzzle from a family photograph;
• An artist uses 3-D printers to create sculptures that would be impractical to produce using traditional techniques;
• Handy homeowners create unique shower heads, curtain rod holders,
  shower caddies, drain screens and more—all designed to perfectly fit a
  specific bathroom space;
• Gear heads create personalized cell phone cases, tablet grips,
  laptop stands and scads of other customized devices/adaptors/holders for
  electronics;
• Do-it-yourselfers create washers, gears, brackets, connectors and other parts that are unique to specific needs;
