How you can 'print' 3-D objects at home

If you hate waiting for days to get an item that you bought on the Internet, here's some good news. Now you may be able to print the object yourself, at home.

Here’s how it works: You design an object, and then a 3-D printer applies small strands of plastic in thin layers until it’s built your product. These machines have been available for professional use for years, but have only recently become (relatively) affordable for personal use.

“It’s about as close as you can get to teleportation,” says Bre Pettis, the inventor of MakerBot, one of the most popular 3-D printers. “It’s like physical objects over the Internet.”

This technology has all sorts of applications. Enthusiasts are printing everything from toys to fashion items to - believe it or not - human organs.

“If you can dream it, you can think it, you can print it,” says Abraham Reichental, CEO and president of 3D Systems Corp. He likens the printing process to building a cake, one layer at a time.

"It really allows you to bring personal manufacturing to the home, to the garage entrepreneur," he says. "You don't have to do it someplace in China."

His company's “Cube” printer hits the market this month and will set you back $1,299. In a demo at CNN's studios, it printed everything from gloves to shoes to a miniature bust of CNN anchor Randi Kaye.

This technology also has medical applications. Dr. Anthony Atala at the Wake Forest Institute for Regenerative Medicine is working on “printing” replacement tissues and organs. He starts by building a 3-D model of a patient’s organ. Then a printer uses cells and biomaterial to build it layer by layer.

The project is still experimental, but it offers exciting potential for patients. Click here to see what the 3-D models look like.

      It's always hard when snhtemiog goes viral especially because even if the company responds (every time) not all will see it. One thing would be to contact the person who originally posted the video to have them delete it. Of course, people could have saved it, but that would help. The original person could also record a follow-up video. The key is for companies to continually monitor the Internet for mentions of their name and respond as quickly and appropriately as possible. It won't stop it, but it may slow things down.

      Good thoughts here, Deb, as alywas. It's a fine line in the evolving world of online PR to respond publicly or take comments off line. I have encountered more and more corporate clients disabling blogs, for instance, because they fear the rogue person who decides to post negative comments whether they relate to that company or not.My view is that if you open the door, be prepared to walk through it yourself. If you make bold statements, be open to input from others. That's how conversation works.Interesting fine lines that I'm sure keep the PR and legal profession up at night.
