A company says it has completed the first 3D-printed home recently. The home was shown to reporters and visitors at a music festival.

The building company has developed large 3D- printers that build homes with mortar, a hard and strong

material. It uses robotics, computer programs and advanced materials to make houses.

Jason Ballard is the company's chief engineer. "So I'm standing in front of the first 3D-printed home in America. This house was actually printed in high winds, blowing dust and rain." It is important for the printing programmes to operate in bad weather conditions, such as weather disasters. The goal is to print homes in developing countries. So the printer has to be light enough to move from one property to the next.

Ballard imagines that someday, many 3D-printers will operate around the world to make homes. "It's actually a lot more simple to build a printer than it is to build a house," he said. "We ran this printer at about a quarter speed to print this house, and completed it in about 48 hours of print time."

The company developed this technology not to make money but to help provide a quick, cheap housing solution for the millions of people who need it most. There are about a billion people that don't have one of life's most basic human needs, and that's safe shelter.

Ballard says his company already works on housing needs with poor families in different areas. But he says that to really make a difference, the program will need to be greatly improved. He added that since the 3D-printing process is so much faster than traditional homebuilding, a whole community could be built in just a few months. He believes over time, people can get the new home below $4,000 with the help of 3D-printers.

It is very important to have a law to base your life on. A law of life that1.(mean) a lot to me is that success is a journey, not a destination(Ä¿µÄµØ).

One person who shares my law of life is Mark McGwire, a US baseball2.(play). He once played for St Lewis Cardinals. He didn¡¯t get caught3. in the home-run competition in the1998 season, but4./?n?sted/ played every game in the best way he could. And, most ofthe time, he helped 5.(he) team. He didn¡¯t just go6. there and hit home runs because he wanted to be ahead in the end, but because he wanted to make it a good season for his team.

I also think my law of life can be applied£¨Ó¦Óã© by the Cardinals. They stay focused on7.(play) in the World Series. They know that even ifthey lose some games, they n8. give up.

It doesn¡¯t matter if you don¡¯t have the9./??b?l?ti/ to be on the top in the end or win the championship. All that matters is that you worked hard the whole time. There are a f10.people in the world know that success is considered as a journey, not a destination. After all, it¡¯s not about who wins or loses, but how well you play the game, and I hope I have applied this in my own life.
