3D printed breathing valve (Image credit: Isinnova)
The COVID-19 epidemic has escalated rapidly overseas, the consumption of medical resources has surged, and various anti-epidemic materials are in short supply
.
Fortunately, a local 3D printing start-up called Isinnova helped the hospital with its immediate needs
.
This is a valve that connects intensive care patients to ventilators, and the valve can be used for up to eight hours at a time
.
Subsequently, another local company, Lonati SpA, was also able to produce more ventilator valves at a nearby factory using polymer laser powder 3D printing technology
.
During the epidemic, 3D printing played an important role in epidemic prevention and control with its advantages of speed, customization and high efficiency

Nose-nose separation mask to prevent glasses from fogging
Nose-nose separation mask to prevent glasses from foggingIn the case of wearing a mask for a long time, the inside of the mask is easy to be wet and uncomfortable.
In addition, when the wearer wears the mask, the glasses are easy to fog
.
For this reason, Weistein 3D printing company from Xiamen produced this KN95•Dual Airflow•Mouth and Nose Separation Mask during the epidemic.
It is easy to wear and easy to replace the filter element.
One filter element can be used for three to five days, making the user safe and comfortable
.
According to reports, the product conforms to the Chinese inspection standard GB2626-2006 KN95, and is sent to the national inspection agency for inspection to reach the standard of KN98 or above, which greatly exceeds the standard of KN95
.
The mouth-nose separation mask is an upgraded version of the traditional mask.
It separates the oral cavity and the nasal cavity to form two fresh air ventilation channels, which effectively prevents the gas containing various odors and bacteria from being exhaled by the nasal cavity again.
The air circulation speed is faster , breathing more easily
.
The material uses food grade PP

Comfortable, safe and environmentally friendly 3D printed mask adjuster
Comfortable, safe and environmentally friendly 3D printed mask adjusterIn order to bring comfort and peace of mind to medical staff, Covestro's Asia Pacific Innovation Center has carefully produced 3D printed mask adjusters
.
In terms of material selection, the regulator is made of Covestro thermoplastic polyurethane TPU material
.
It has high elasticity, moderate softness and hardness, which relieves the discomfort of wearing for a long time and has wear resistance and weather resistance; it is also safe and environmentally friendly, can be washed with soap or bleach, disinfected with alcohol, and can be reused many times
.
In addition, Peak also combined traditional sports shoe printing technology to produce a mask adjuster that is "wear-resistant, breathable, flexible, non-slip, environmentally friendly and recyclable" within 4 hours, which can effectively reduce the discomfort to the ears when wearing a mask
.
The P4U+TPU printing filament used in this "mask adjuster" was jointly developed by Peak Xi'an New Materials R&D Center and Wanhua Chemical
.
Peak also uses the method of "adding velcro" to quickly iterate on the product.
The newly added velcro small mouth can not slide up and down when wearing a non-woven hat, and it is very stable.
Worn ears are no longer present

Reusable personalised 3D printed protective face shield
Reusable personalised 3D printed protective face shieldA few days ago, institutions such as the National Additive Manufacturing Innovation Center and Xi'an Qitai Coordinate Medical Technology Co.
, Ltd.
used 3D printing technology to quickly complete the finalization of individual 3D printed protective face shield products, link optimization, and finished product production
.
The R&D team mainly conducts three-dimensional modeling based on the wearer's head and face scan data, and can complete a personalized protective mask in 2 hours, which can be reused after disinfection
.
The 3D printed face mask is customized and can be accurately attached to the user's facial skin, which can greatly improve air tightness, reduce local pressure, greatly improve the fit and relative airtightness of the mask, and alleviate the ear damage caused by wearing the mask.
pain
.
The adjustable buckle design can adjust the tightness of the wearing according to the individual head shape, so that the mask fits better, the protection is more in place, and it is not easy to slip off, and it can also reduce the consumption of the mask

Unmanned manufacturing of 3D printed goggles is more anti-fog and lighter
Unmanned manufacturing of 3D printed goggles is more anti-fog and lighterHunan Yunjian Group Co.
, Ltd.
uses its existing 3D printing technology reserves to produce medical goggles, which not only have good anti-fog effect, high sealing, and only 3/4 of the weight of ordinary goggles, but also can be realized according to personal facial data.
Personalized customization
.
During the production process, the positions of the wearing holes on both sides and the optimization of the facial curves were improved a dozen times
.
The company said that 3D printing has the advantage of rapid emergency production.
In special periods such as the epidemic, it can realize unmanned manufacturing, reduce the spread of the epidemic, and can also share data models, realize network collaborative production, and improve parallel production efficiency

3D model of the country's first new coronavirus lung infection case
3D model of the country's first new coronavirus lung infection caseRecently, the country's first 3D model of a new coronavirus lung infection case was successfully modeled and printed
.
It performs 3D reconstruction based on the CT data of the lung lesions when the infected person was diagnosed 5 days ago.
The 3D printing provider-Shapingyou Technology flexibly adjusts the Shore hardness, transparency and color by relying on the Stratasys J750 printer and PolyJet materials to realistically restore the lungs of the new coronavirus.
Infection cases
.
In the model, the ground-glass image features of the new coronavirus are clearly presented, which helps medical experts to analyze and deduce case entities more intuitively
.
3D printed hands-free door opener
3D printed hands-free door openerDuring the epidemic, preventing direct contact with objects can reduce the chance of infection.
To this end, Belgian 3D printing company Materialise designed a 3D printed hands-free door opener, which allows people to open and close the door with their arms, avoiding the need for hands and door handles direct contact
.
Anyone with a 3D printer can go to the Materialise website to download the design file and have it printed in a few hours
