Fighting COVID-19 with 3D Printing
The INNO3D team from UTBV took the initiative of Prof. Santiago Ferrándiz Bou, Universitat Politècnica de València, Spain and coordinated a local project for the production of face shields for medical staff in hospitals in Brasov. In the team were involved 10 student volunteers and 3 teachers, which produced around 800 face shields distributed in 11 hospitals in Brasov.
The action was disseminated in the local media as follows:
These initiatives have provided valuable help for medical staff in the fight against CORONAVIRUS, including testing devices and face shields.
The materials used were PLA and PET-G, with PET-G mechanical strength.
There were many problems with the supports made of PLA when the protective foil was mounted on the support (many supports were damaged or even broken).
PET-G behaved best, when considering the purchase price was not much more expensive.
Also, the quality of the surfaces of the media printed with PET-G was clearly superior to those made of PLA.
Starting from the 2 models, optimizations were made so as to reduce the working time (important in these conditions) and to obtain face shields that meet the users' requirements (ensuring good ventilation on the face, comfort in use, the possibility of sterilization). Improvements have also been made to the design of the face shields, some of which are inscribed with the name of the Transilvania University of Brasov.
The PRUSA company as well as other internationally renowned companies have contributed and continue the process of making medical equipment, specific to the field of Medical Engineering, in open access format. This phenomenon has led, in a very short time, to a new technological period through which, under certain conditions, expensive equipment for the maintenance and upkeep of life as well as for protection against viruses are replaced. These face shields are just an example of the vast field, open access, current.
