Student Car Mechanic Helps Med Team Print 3D Ventilator

German scientists have created a ventilator in seven days using a 3D printer - with a little help from a student car mechanic who worked nights to help put it together.

The project was a close cooperation led by Dr Ronny Grunert from the University of Leipzig together with experts from the West Saxony University of Applied Sciences and the Fraunhofer Institute for Machine Tools and Forming Technology.
