In times of need, neighbors help each other. The Hong Kong Polytechnic University has been collaborating with the nearby Queen Elizabeth Hospital and the Hospital Authority to design and produce 3D-printed eye shields and face shields in the fight against the coronavirus outbreak.
In just 10 days, the university mobilized all the 3D printers in the University Research Facility in 3D Printing and other departments to operate 24 hours a day to produce 700 eye shields and over 800 face shields.
"During the coronavirus outbreak, solidarity is one of the essential elements to battle the disease. The partnership is a good example of the sentiment 'when one place suffers, aid comes from all sides.' We should join hands to overcome these difficult times together," said PolyU provost designate and vice president of research development Alexander Wai Ping-kong.
With support from the local manufacturing industry, face-shield production was increased to 10,000 pieces per day by late February, and will reach 30,000 per day by later this month.
The entire process - from design to mold-making and finally production - took just a fortnight.
"Designed by PolyU and made in Hong Kong, this is a testament to the skill and capability of the Hong Kong manufacturing industry. We can do it and we must do it," said Man Hau-chung, dean of the faculty of engineering and director of the University Research Facility in 3D Printing.
"Since the face shield is a one-off disposable item, we chose a less expensive PLA filament material to make the 3D printed frame and attached it to a clear plastic film. We also made use of the studies of our school of design in comparing the head sizes of Asians and Westerners to design a face shield that better fits Chinese wearers."
The shields were much appreciated, said the Hospital Authority's chief manager for infection, emergency and contingency Vivien Chuang Wai-man.
"PolyU made every effort to develop a quick solution for rapidly producing face shields and helping us line up domestic production. We can replenish our stockpile to meet our needs during the outbreak."
