3-D Printers Are Changing The World

The world’s first 3-D printed school has opened. Where will this technology take us next?

As You Read: Identify three differences between 3-D printers and older printers. 

Imagine waking up one day to find a new school next to your house. It popped up overnight. 

This happened in June in a village in Malawi, a country in Africa. The village has the world’s first 3-D printed school. Its concrete walls were built in about 18 hours.

Printing a Better Way

Before the school opened, many kids in the area had to walk miles to school. Other villages in Malawi have the same problem. Now 3-D printed schools can help!  

The first 3-D printers were made in the 1980s. But technology has changed a lot since then. Just ask Easton LaChappelle. He started a company that makes 3-D printed prosthetic arms.

“3-D printing has come a long way,” he says. “It’s a lot faster now.”

Today’s 3-D printers crank out everything from shoes to houses.

How They Work

A 3-D printer is different from ones that use ink and paper. 3-D printers use materials such as plastic or metal. They create three-dimensional objects with height, length, and width.   

3-D printers are better in many ways than old types of manufacturing. People can make things as they need them. That can save time and money. 

For example, shipping supplies from Earth to the International Space Station costs $10,000 a pound! Astronauts with a 3-D printer could simply print items as they need them. 

3-D printing also reduces waste. It uses just enough material to make an object.

Another plus is that these printers can make complex shapes. People can get prosthetic limbs specially made for their bodies.

A 3-D Future

So why don’t we 3-D print everything? It’s still cheaper to make many copies of items in factories. But 3-D printing is changing the world, one step at a time. 

LaChappelle can’t wait to see what the future holds. He says, “It’s amazing to think about what might be next!”
