From Learning English, this is the Technology Report.
There are increasing calls for lawmakers to reconsider copyright laws that protect the owners of 3-D printing designs. But there is also concern that extensive laws could suppress new ideas. 3-D printers have spread from scientific labs to industrial workshops to private homes. And prices of 3-D printers continue to drop.
Designers demonstrate a large number of different machines at 3-D print shows. There are models that can produce complex copies of human organs. There are less costly 3-D printers that make toys for children or parts for home electrical devices.
One German automaker recently demonstrated an example of a car structure printed in one piece. And a Chinese manufacturer advertised a house created in a 3-D printer.
With the help of computer, almost anyone can print exact copies of many kinds of objects. But they also violate the law in doing so.
Julie Samuels is a lawyer with the civil liberties group, Electronic Frontier Foundation. She says people should be careful about what they create when using 3-D printers.
If a certain design that you want to print is covered by copyright, then if you print that you are infringing, arguably, someones copyright, said Julie Samuels.
But 3-D companies are concerned about passing more restrictive copyright protection laws. They think these laws could place bans on the rights of citizens. They also believe restrictive copyright laws could suppress technological invention.
