Additive manufacturing ensures quick and cost-effective production of medically-safe nasal swabs for COVID-19 test kits. The Australian company 3D Printing Studios is the first supplier in the country of these essential medical devices in the current time.
We have been able to 3D print nasal swabs used for testing COVID-19 and other communicably transmitted diseases by using EOS AM systems. These swabs have a special head design with flocking added and have recently been shown to successfully collect sufficient human cellular material and mucus used in COVID-19 and other testing processes.
In order to meet the sudden demand for key medical supplies during the COVID-19 pandemic, many countries and businesses have turned to local manufacturers and alternate manufacturing technologies like additive manufacturing.
There is an urgent need to design new medical devices that are reliable and can be efficiently mass manufactured with 3D printing. It exists a sudden surge in demand for new products such as PPE (face shields, eye protectors etc.), ventilators and - in that case - nasal swabs.
In Australia, 3D Printing Studios quickly worked with the state government and health departments to produce medical nasal and throat swabs for use in COVID-19 test kits.
We’ve tried several different 3D printed designs obtained from Harvard Medical School and finally came up with a simple design that is flocked with a safe nylon material. The design, coupled with the EOS P 396 system, will allow us to produce thousands of these medical swabs per day.
3D Printing Studios is leveraging their experience with additive manufacturing to help speed up the design and production of nasal swabs for COVID-19 test kits. The biocompatible polymide material EOS PA 2200 was selected due to the known stability and reliability of its mechanical properties after sterilization by autoclave or radiation process.
Additive manufacturing enables agile design and quick evaluation cycles of the nasal swabs. This quickly compresses the time required for product development, engineering production trial and functional lab trials of the test kits.
In addition, the EOS P 396 system was selected to manufacture the nasal swabs, as this AM technology was most cost-effective when compared to other additive manufacturing technologies.
