AUTOMOTIVE AERODYNAMICS
Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case. For some classes of racing vehicles, it may also be important to produce downforce to improve traction and thus cornering abilities.

TEST PRINT AND PROCESSING:
After the second successful test print, the whole car what printed. in which brief sanding was imposed.
After sanding, layers of white paint were painted onto the final print to get an even coat. after which full painting was resumed.
