The medical business’s adoption of 3D printing is effectively documented and widespread. There are printed hips, trachea, bladders, cranial implants, and far more. With the continued unfold of the coronavirus, 3D printing is proving helpful in yet one more medical utility as an emergency response device. Polytechnic College in Hong Kong is 3D printing face shields for hospital employees who’re working low on provides.
We’ve got labored with hospitals earlier than to provide tools for coaching functions, however by no means for one thing so sensible. Sidney Wong Wing-fai, engineering supervisor on the PolyU printing lab.
When battling extremely infectious illnesses, sterilization is critically vital. Some of the efficient measures of sustaining a sterile atmosphere is to work with single-use objects, akin to syringes, bandages, and face masks. On this case, the Hospital Authority estimated that hospitals had solely 450,000 medical face shields in inventory. Which will sound like so much however since they’re single-use, it’s solely a couple of month’s price.
The Hospital Authority reached out to the college in early February. Alexander Wai Ping-kong, the college’s vice chairman for analysis growth, mentioned “The face defend may be very easy to provide.” It consists of a transparent plastic sheet connected to a body that matches onto the brow and is held in place by an elastic band. The researchers in Polytechnic College’s 3D printing lab designed and prototyped the frames in solely every week, which incorporates optimizing the ultimate design based mostly on direct suggestions from hospital staff who examined the prototypes. For 2 weeks, six lab technicians managed 30 3D printers that have been churning out frames; the techs additionally assembled the frames into face shields as they got here off the printers.
A primary run of 800 face shields was produced by PolyU however future batches can be produced by native producers, with a objective of constructing 30,000 per day by late March. Man Hau-chung, dean of the engineering division that oversees the printing lab, emphasised the significance of constructing the face shields regionally: “PolyU is doing expertise switch to the business, and for business to assist the Hospital Authority and society. A very powerful factor is to make it in Hong Kong, and that we will have our personal ample provide.”
If the coronavirus is to be contained, a fast response from quite a lot of industries and companies is critical. Let’s hope they will all present options as shortly because the PolyU 3D printing lab.
