To this day and despite the fact that the designs of the new twelve stadiums that will host all the football matches of the World Cup to be held in Qatar In 2022, the truth is that work is still being done to make them a reality by looking for the ideal materials, technologies to be used ... According to the University of Qatar, responsible for all this work, it is essential, due to the design of almost all stadiums, to test with technologies such as 3D printing to make them come true.
One of the first steps that are being taken, due to the particular climate of the country, is create mockups using 3: 1 scale 300D printing of each of the 12 stadiums to later introduce them into a wind tunnel and thus be able to study the aerodynamics of the designs with the help of lasers. This step is essential since it is necessary to optimize air circulation as much as possible at the same time that this can help enormously to reduce construction costs and especially the environmental impact.
In order to create these models, according to the experts of the Qatar University who work with them, has opted for the acquisition of a Fortus 3mc 400D printer manufactured and marketed by the company Stratasys. On the other hand, once the stadium has been manufactured and assembled, it is placed in a wind tunnel specifically designed for this project. Once all kinds of data have been obtained, they are entered into a computer to be able to carry out the pertinent simulations.
Based on the statements made by the teacher Saud Abdul Aziz Abdu Ghani:
We can visualize the temperature at each level, introduce variables such as the number of spectators and even the sweat they generate, then carry out a simulation and see the effect of temperature inside the stadiums.
Thanks precisely to the studies that are being carried out on the stadiums, the Qatari authorities have been able to introduce a series of aerodynamic changes which, in turn, have given the opportunity to reduce the amount of steel used for their roof structures, which ultimately translates into savings in construction costs and their environmental impact.
