Lube Volley, the team

A tangible collaboration, thanks to 3D printing

When Enrico Diamantini and Ivan Zaytsev, two prominent athletes from the club, expressed their need for new hand protection devices during games, the relationship between Lube Volley and Prosilas evolved beyond a simple sponsorship. Prosilas immediately utilized its expertise in 3D printing to develop an innovative, customized, and tailored solution for both players.

‘We took the opportunity to get even closer to the world of medicine and sport, trying to develop a truly useful and professional application,’ says Vanna Menco, CEO Prosilas

Diamantini required an alternative to the temporary brace he had been using to support his injured right little finger, while Zaytsev needed a replacement for the medical tape he typically used to stabilize his fingers during high-impact phases of the game.

The previous solutions had limitations in terms of materials, lacking of technical performance, reusability, and customization, which resulted in a sub-optimal playing experience. However, with the advent of 3D printing, Prosilas believed that they could overcome these limitations and produce custom-made and reusable devices with exceptional speed and precision.

For Diamantini, the old brace was rigid, bulky, and therefore uncomfortable. The negative impact on his ball touch led him to use it sporadically and only for the minimum required time. Similarly, Zaytsev sought a custom-made, reusable alternative that provided better sensitivity compared to traditional medical tape.

Through their collaboration with Prosilas, both athletes found the solution they were looking for, addressing their specific needs and improving their playing experience on the court.

Fast and successful product development

 The initial phase of the project focused on acquiring the 3D models of Diamantini and Zaytsev’s hands using the Gom Atos 5 3D scanner, which involved scanning plaster casts. Subsequently, the design phase commenced, incorporating reverse engineering techniques to accurately model customized designs. These designs were tailored to protect and immobilize the injured joint in one case, and provide comfortable support in the other. The devices underwent testing and, with valuable feedback from the athletes, were progressively refined to achieve the best possible results.

“The responsiveness of additive technology is truly remarkable. The initial contact with the players took place in October 2022, and after just five rounds of improvements, we were able to arrive at the final version of the devices for both players within a very short timeframe,” states the CEO of Prosilas.

Testing phase and results

“The results achieved through the utilization of additive technology are undeniably positive,” remarks Vanna Menco. “This is further corroborated by the outcomes of resistance tests conducted on the material by our supplier, BASF 3D Printing Solutions.”

 The testing phase was a critical step in the process. Collaborating with BASF, an effort was made to replicate a volleyball game in a laboratory setting. This involved evaluating the material’s chemical resistance, short and long-term durability, as well as color stability.

The remarkable durability and strength of the custom 3D-printed devices can be deduced from the absence of significant degradation observed during testing. This ensures the longevity of the product even under repeated stress and in special chemical conditions. Apart from the scientific findings, the enthusiastic feedback from the athletes themselves confirmed the positive results and the significant improvement in playability and game feel.

The combination of improved performance, stable feel, durable material, and complete customization results in an overall increase in comfort for athletes during competition, leading to an enhancement in playing performance.

Customization has become an essential trend in the world of ultra-competitive champions, and additive solutions go above and beyond by offering specific shapes and characteristics tailored to each individual athlete’s needs.
