3D-printed houses

There are ten new buildings in Shanghai, China. These buildings are special. They are not made of bricks. The buildings were printed.

A 3D printer uses a special material. It puts this material in layers. It puts one layer on another. The layers are well connected. They will not move apart.

The walls are only three centimetres thick, but the material is very strong. It is five times harder than normal materials.

Difficult words: brick (hard piece of material which is used for building), layer (material which covers something), connected (to touch).

You can read this story  in the Level2 section.

Ten grey building were built in Shanghai. They may look like normal houses from a distance, but they are quite special. They are China’s first buildings made with 3D printing technology.

The houses were built without using bricks or tiles. The walls are made of a special mixture of materials like sand or concrete. This material is printed by 3D printers which were developed in East China. The printers lay one layer of the material on top of another.

The layers are well connected and they will not deform. The layers are only three centimetres thick, but they are five times harder than normal materials.

Difficult words: tile (flat square piece which is used in buildings), concrete (material which is used for building), layer (amount of material that covers a surface of something), deform (to change shape).

You can read the original story  in the Level 3 section.

From a distance, these buildings may look like any regular brick structure, but close up you can see that their walls are made of hundreds of layers piled up together, as these are actually China’s first buildings made with 3D printing technology.

The ten grey coloured buildings have been erected in Shanghai without using a single piece of brick or tile. The wall bodies are made with a special mixture of carefully selected raw materials including sand, concrete and glass fibres, and they were printed out by 3D printers which were developed in East China.

The layers are approximately three centimetres thick but five times as hard as common construction materials.

“The building materials are all printed out by our 3D printers layer by layer and we pile them up. All the layers are firmly connected with each other. They won’t separate, neither will they deform and collapse.”

A number of workers have already moved into the buildings to use as their everyday offices.

Difficult words: pile (place things on top of another), erect (build), tile (flat square piece of baked clay), fibre (thin line of something).
