4D Printing will play a key role in future vehicle production. For example, the outer shell of the BMW VISION NEXT 100 could change shape in response to air flows if printed in 4D. Its wheel arches, which dynamically move in synch with every steering movement could also be produced in the same way..
4D Printing therefore provides a basis for setting new standards in kinematics, performance and design. Whilst in the field of aerodynamics, it could play a major role in helping optimise flow behaviour – leading to significant reductions in a vehicle’s drag factor (cW value).
