Maker’s Guide| 3D Printed Protective Goggles to Prevent Yourself from the Novel Coronavirus

The novel coronavirus epidemic is putting the whole country into a predicament of medical supply shortage. As the NCP is confirmed to cause transmission mainly through droplets, face masks, and protective goggles have become the essential types of equipment to reduce the infection risk.

3D Printed Protective Goggles Go to the Frontline of Epidemic Prevention and Control

News reported that Vangaurd, a Hunan-based ordnance equipment company, designed and produced medical goggles FDM-1 which has been registered and approved by Changsha Market Supervision Bureau. On Feb. 10th, the company sent the 3D printed medical goggles to Wuhan, which greatly mitigates the predicament of medical supplies shortage confronted by medics.

From design to production and to use, it only takes 153 hours within 7 days. According to team leader Yang Kai, “We’ve tried different molding technology and made tens of adjustments on the protective goggles, taking 153 hours to deliver the final results. 3D printing has the advantages of rapid and effective production, which greatly reduces the manufacturing time on each piece.”At present, the company has 50 3D printers to work continuously for 24 hours, achieving the daily output of 300 pairs. If there are 3,000 3D printers, the daily output will definitely excess 10, 000 pairs.

Compared to common goggles on the present market, the 3D printed FDM-1 medical goggles broads the advantages of lightweight, better anti-fog effect and higher sealing effect. Besides, FDM-1 can be customized in accord with personal facial contour, making it perfectly fitted on.

Are Protective Goggles Truly Necessary in Coronavirus Prevention?
As rumors go that the novel coronavirus can be transmitted through aerosols even over a distance of 13 kilometers, it will greatly increase the infection possibility on each random person. Actually, aerosol propagation refers to the nucleus composed of proteins and pathogens that are lost by the droplets during the air suspension process. The aerosol particle size is usually 0.1 mm and below, and the propagation distance can reach hundreds of meters. Infectious aerosols are mostly generated when a patient coughs or sneezes, so it is necessary for a medic to wear protective clothing, masks, and goggles during the sputum, intubation and other treatments. However, the infection activity will be significantly reduced after the virus floats in the air for two hours, which means the probability of exposure to infectious aerosols by residents is extremely low.

In a word, protective goggles are really important for medics. We residents don’t have to wear protective goggles all the time. During the grim situation of coronavirus prevention and control, medical protective goggles need to be spared to medics fighting at the frontline.

How to DIY 3D Printed Protective Goggles to Prevent Coronavirus Infection?
Except all the superiorities mentioned above, 3D printing can also achieve online date sharing and network collaborative work. Here we get the opportunity to take a look at a Creality user making protective goggles on Creality CR-10 Max.

1. Design the digital model of the protective goggles. Since we have the ready-to-use digital file in hand, makers can directly go to the 2nd step.

2. Make sure all the settings are correct in the slicer software, especially the layer height, print speed, and etc.

3. Import the STL file into the 3D printer and start printing.

4. When the final print comes out from the 3D printer, you can start fixing glass and an adjustable belt to the goggles.
