Corona face masks created on a 3D printer

Fast, direct help from Ziehl-Abegg for the Hohenlohe district – how the company manufactured the masks on 3D printer.
The risk of infection due to Covid-19 to personnel in the health and care sector must be kept a minimum. So, the German fan manufacturer Ziehl-Abegg has created face masks on 3D printers and handed them over to the District Administrator Dr Matthias Neth. “Our employees and their families work and live here – so naturally we provide them with as much support as we can, particularly during a crisis such as this,” says CEO Peter Fenkl. A Ziehl-Abegg employee had by chance been sent a set of build instructions via WhatsApp on the Wednesday evening – and on the Thursday morning Ziehl-Abegg sent a photo of the first face masks to the Crisis Team in the Local Administration Office. Once it gave the immediate go-ahead, both 3D printers went to work at the Künzelsau InVent Development Centre.
“We have been using 3D printing technology since 2010,” explains Achim Kärcher, Laboratory Director at Ziehl-Abegg. The Development Centre already had its second 3D printer by the following year. The cost of a unit is about 100,000 euros. The layers are printed at a thickness of 0.16 millimetres. “We normally use this to create prototypes for implementing new ideas from our engineers,” explains Kärcher. Ziehl-Abegg is a technology leader in biomimetic-based fan design; “so we need to be able to trial new shapes quickly and easily,” adds the Laboratory Director.
The process of creating the protective masks was also quick and easy: the frame is printed, the lens is a foil for an overhead projector, a standard perforator punches the openings, with rubber bands used for fastening. District Administrator Dr Matthias Neth says he is also pleased with the “simple but effective” design. He will be passing on the temporary face masks to the ancillary staff in the Hohenlohe district. “We will get through this crisis together and can depend upon on each other,” said Neth. “The District Authority is working in close cooperation with the local companies in the Hohenlohe district,” adds the District Administrator.
“We’re pleased about being able to help employees in the health and care sector in this way,” says CEO Fenkl. The medical sector is also part of the company’s normal area of business: for years now, Ziehl-Abegg has been producing large fans for both operating theatres and quarantine stations. The company supplied special fans for Chinese hospitals that were built in the cities of Wuhan, Shandong and Shenzhen within just a few days. The German company also manufactured the core equipment for negative or positive pressure in clinics in Italy and other countries. It is also currently still working at full speed manufacturing these fans in Hohenlohe and worldwide.
Ziehl-Abegg (Kuenzelsau, Baden-Wurttemberg, Germany) is one of the leading global companies in the field of ventilation, control and drive technology. Back in the Fifties, Ziehl-Abegg established the basis for modern fan drives: external rotor motors which even today are still seen as state-of-the-art worldwide. Another area of business is electric motors which provide the power, for example, for elevators, medical applications (computer tomography equipment) or deep-sea underwater vehicles. The theme of electro-mobility for motor vehicles was established as part of the Ziehl-Abegg Automotive Team in 2012. The high-tech company has an impressive innovative capability.
