LAS VEGAS — Even though 3D printing is all the rage at the Consumer Electronics Show, many people outside the industry are still puzzled by all the fuss.

“Explain 3D printers to
me. Why are they useful?” one non-techie friend of mine tweeted me this
week, after I posted a picture of a 3D printer at the show.

By the way, there are 28 3D printing exhibitors at the show, up from
just eight in 2013, according to Gary Shapiro, the president and chief
executive of the Consumer Electronics Assn., which organizes the show.

“It puts the power to make an object or manufacture an object in

Another company at the show was XYZprinting, which plans to start
selling a 3D printer called the Da Vinci later this year for $499 — one

said the 3D printer can quickly create objects that users may need in
their homes, such as a plastic cup or a plastic spoon.

“With 3D printing, you just get a design from the Internet, press the button and print at home,” he said.

Right now, users can download files in order to create objects using a
3D printer. They can also create objects using software such as

Gyorgy Simo, chief executive of Leonar3Do, the makers of Leopoly,
compared the potential of 3D printers to that of the Internet, saying 3D
printers could change the world. While the Internet gave users the
ability to have instant access to information, 3D printers will give
users the ability to instantly create objects.

In the future, users may be able to print shoes that are tailored to
the exact size of their feet, among many possibilities. They may also be
able to buy products directly from online retailers and print them out
immediately, rather than wait for the item to ship.

“It’s closer than you think,” Simo said.
