The application of 3D printing technology in the medical industry has been greatly appreciated. There are models such as printing trachea, bladder, skull implants, etc. with the continuous spread of the new crown epidemic situation, 3D printing technology, as an emergency response tool, has once again verified its important role in medical application. Xianggang University of technology uses 3D printers to make 3D printing masks to solve the problem of protective materials for hospital staff Shortage problem.

Sterilization is essential in the fight against highly infectious diseases. One of the most effective ways to maintain a sterile environment is to use disposable items such as syringes, bandages and masks. In this case, the hospital authority estimates that the hospital's inventory is only 450000. This may sound like a lot, but because they're disposable, they're only smart for a month.

The hospital authority contacted the University of Science in early February. "It's very easy to make masks," said Wei Pinggang, vice president of research at the University It consists of a transparent plastic plate fixed to a frame mounted on the forehead and held in place by elastic bands. Researchers at the 3D printing Laboratory of the University of technology designed and prototyped the framework in just one week, including optimizing the final design based on direct feedback from hospital staff who tested the prototype.

In two weeks, six lab technicians called 30 3D printers that were producing frames, and assembled masks when the frames were removed from the printers.

Li Da has produced the first 800 masks, but the future batches will be produced by local manufacturers. Next 30000 masks will be produced every day. Wen Houzhong, director of the engineering department in charge of the printing laboratory, stressed the importance of manufacturing protective masks in the local area: "Li Da is transferring technology to the industry, providing help to the industry, helping the hospital authority and the society. The most important thing is to make it in Hong Kong, and we can have our own sufficient supply. "

If we want to contain the coronavirus, we need rapid response from various industries and institutions. It is hoped that they can all provide solutions as quickly as the 3D printing laboratory.
