They say that this 3D -printed bicycle helmet is the safest

A new bicycle helmet with a geometric design can help detain the cyclists safer, reducing the head injuries. Developed by researchers from universities in Gotyrg and Isfahan, 3D -printed helmet This can better absorb blows that traditional helmets with foam at the exhibition, deforming their shape as necessary.

Like the principle of deformation zones in the car, the idea is that the inner layer of the helmet is reduced and absorbs energy, so less strength reaches the cyclist’s head during a collision.

“When exposed to the energy of exposure, the coating material is reduced, and this improves the absorption of energy energy, which means a lesser risk of injuries for the leader of the cyclist as a result of an accident,” explains the chief researcher Mokhsen Mirhalaf from the University of Getberg. “We use a specific method of design optimization to determine the best possible geometric configuration to minimize shock forces. The geometry of the structure of the material is a key factor. “

The geometry of the helmet was calculated using computer modeling and then printed using 3D printing. In the printed version, a material called a hyperlastic polymer was used, which can stretch, contract and deform, and then return to its original form. The team checked the printed version before traditional foam helmets in two types of shock scenarios and found that the new version better protects the head.

In addition to providing better protection, the 3D -printed helmet is also easier, and its shape can be tuned for the head of a separate cyclist. Researchers suggest that this can be useful for professional athletes, or for those who are currently available, uncomfortable bicycle helmets, although the helmet printing technology means that it is currently more expensive than traditional models.

“With a greater development, this technology can lead to a new generation of bicycle helmets, which are safer, comfortable and more customizable,” Mirhalaf said. “Despite the fact that the 3D printing technology is currently more expensive than the foam coatings produced as a result of the masses are expected that the costs will decrease, since the technology will be used more widely. In the future, it may even be possible to print personalized helmets on demand, guaranteeing that every cyclist receives the best possible protection. ”
