3D-printed vertebra used in spine surgery

Wow.

Surgeons in Beijing, China, have successfully implanted an artificial, 3D-printed vertebra replacement in a young boy with bone cancer. They say it is the first time such a procedure has ever been done.

During a five-hour operation, the doctors first removed the tumor located in the second vertebra of 12-year-old Minghao’s neck and replaced it with the 3D-printed implant between the first and third vertebrae, CCTV.com reported earlier this month.

“This is the first use of a 3D-printed vertebra as an implant for orthopedic spine surgery in the world,” said Dr. Liu Zhongjun, the director of orthopedics at No. 3 Hospital, Peking University, who performed the surgery.

China: Firm 3D prints 10 full-sized houses in a day

Awesome!

A company in China has used giant 3D printers to make 10 full-sized, detached single-storey houses in a day, it appears.

A private firm, WinSun, used four 10m x 6.6m printers to spray a mixture of cement and construction waste to build the walls, layer by layer, official Xinhua news agency reported.

The cheap materials used during the printing process and the lack of manual labour means that each house can be printed for under $5,000, the 3dprinterplans website says.

“We can print buildings to any digital design our customers bring us. It’s fast and cheap,” says WinSun chief executive Ma Yihe. He also hopes his printers can be used to build skyscrapers in the future. At the moment, however, Chinese construction regulations do not allow multi-storey 3D-printed houses, Xinhua says.

China: World’s fastest elevator to be installed in Guangzhou

Awesome!

The fastest lift in the world is to be installed in a skyscraper currently under construction in the southern Chinese city of Guangzhou, it seems.

The lifts at the Guangzhou CTF Financial Centre, which will be ready in 2016, will be able to reach a speed of 72km/h (44mph), the South China Morning Post reports. This means it will take just 43 seconds to travel 95 floors up the 440m shaft.
