3D Printed Cast Could Heal Bones 40 percent Faster; 3D Printers Print Ten Houses in 24 Hours

From Telegraph:

A 3d printed medical cast could help bones to heal up to 40 per cent faster.
The black cast, known as the Osteoid, uses an ultrasound system which makes bones heal more quickly.
With a lattice pattern, it is filled with ventilation holes which the designer says means it does not smell or itch- unlike traditional casts.

The cast is combined with a low intensity pulsed ultrasound system, known as LIPUS, for 20 minutes a day, which the designer claims will reduce the healing process of fractures by up to 38 per cent.

From Xinhua:

A private company in east China recently used a giant printer set to print out ten full-sized houses within just one day.
The stand-alone one-story houses in the Shanghai Hi-Tech Industrial Park look just like ordinary buildings. They were created using an intelligent printing array in east China's city of Suzhou.
The array consists of four printers that are 10 meters wide and 6.6 meters high and use multi-directional automated sprays. The sprays emit a combination of cement and construction waste that is used to print building walls layer-by-layer.
Ma Yihe, the inventor of the printers, said he and his team are especially proud of their core technology of quick-drying cement.

This technology allows for the printed material to dry rapidly. Ma has been cautious not to reveal the secrets of this technology.
