Innovation in Soccer: Study and Implementation of Protective Masks through 3D Printing

3D Printing in the Development of Sports Protective Devices

Simone Gallozzi Demonstrates Its Potential in His Thesis

Sport and 3D Print

The world of sports is constantly seeking innovative solutions to enhance athletes’ performance, reduce the risk of injuries, and facilitate recovery.

3D printing, in particular, is emerging as an increasingly popular technology, enabling the production of customizable protective devices such as prosthetics, running shoe soles, helmets, and other safety gear – as exemplified by our Case Study on Lube Volley.

In particular, Simone Gallozzi’s thesis demonstrates the feasibility and details the workflow of a 3D printing application in the field of soccer

The candidate, in his thesis titled ‘ADDITIVE MANUFACTURING IN THE SPORTS WORLD – Analysis and Production of Facial Protective Masks in Soccer,’ under the guidance of Professor Eleonora Santecchia, conducted a thorough analysis on the application of 3D printing in sports.

His main objective was to explore the production of protective devices through 3D printing, both for the maxillofacial area and other parts of athletes’ bodies.”

Case Study: Maxillofacial Protective Mask

The heart of the thesis is represented by the Case Study, in which Gallozzi,student
of Mechanical Engineering at the Università Politecnica delle Marche, collaborated with our company in the development of a maxillofacial protective mask designed for soccer players.

Material and Printing Technology Selection:

The first step involved choosing the most suitable material and printing technology for the application.

In this case, the chosen material is PA603CF, a composite of PA2200 loaded with carbon fiber.

Its ability to provide high-performance, coupled with its resistance to the stresses typical of the soccer environment, makes it ideal for the production of advanced protective devices.

The selected printing technology is SLS (Selective Laser Sintering), enabling the precise and durable printing of PA603CF parts.

Design and Production Workflow

1 – Modeling and Printing of Specimens for Tensile and Flexural Testing:

Prior to the production of the mask, validation tests of the material were conducted, in accordance with UNI EN ISO 527-2, 1A, and ISO 178 standards.

The specimens modeled using Siemens NX passed tensile and flexural tests, confirming the suitability of PA603CF for the maxillofacial protective mask.

2 -Face scanning:

The next phase involves the 3D scanning of the subject’s face for whom the mask has been modeled.

This scanning is performed using a 3D scanner, which captures the shape and size data of the face.

The acquired data is then used to create a 3D model of the mask that perfectly fits the subject’s face using reverse engineering techniques

3 – 3D Modeling:

The 3D model of the mask is created using Siemens NX, a 3D modeling software. The model is designed to protect the most vulnerable areas of the face, such as the cheekbone, jaw, and nose.

Consideration for comfort and lightness was crucial, along with the desire to preserve the athlete’s peripheral field of vision to the maximum extent possible.

4 -Prima realizzazione del prototipo

Prima di procedere con la maschera finale, è stato creato un prototipo in VeroWhitePlus con la stampante 3D Objet30 di Stratasys, che sfrutta la tecnologia di material jetting.

Questo passo preliminare ha consentito di valutare la bontà del design prima di passare alla fase successiva.

Last phase, finally the mask is printed

5 –3D Printing with SLS Technology and PA603CF Material

Once the success of the prototype was confirmed, the 3D printing of the final protective mask in PA603CF was initiated using our company’s SLS 3D printers.

This phase represents the culmination of the thesis work, with the chosen material selected for its intrinsic properties of rigidity, strength, hardness, and lightness.

Post-Printing Phases: Safety and Customization

Simone Gallozzi theoretically discussed post-printing phases, including the need to internally coat the mask with a soft material for skin contact. He proposed the use of strategic supports to avoid contact with the traumatized area.

Surface treatments and aesthetic customizations are considered to enhance the appearance of the mask, completing the process with the addition of elastic bands through designated holes.

 

Simone Gallozzi’s work represents a very interesting application of Additive Manufacturing in the world of sports, highlighting how collaboration between academia and industry can open new perspectives for innovation.

From idea to prototype in 4 months, Bimota streamlines times and costs for its motorcycles with Prosilas’ 3D printing.

From idea to prototype in 4 months, Bimota streamlines times and costs for its motorcycles with Prosilas’ 3D printing.

Bimota + Prosilas Case History

Thanks to Prosilas’ additive manufacturing, the Rimini-based company develops new high-performance models within a few months. This cuts down both time and costs, resulting in absolute excellence on the road and the track.

Bimota is the historic motorcycle manufacturer, founded in Rimini in 1973. Over the years, the company has undergone various changes and evolutions, leading to its revival through the acquisition by Kawasaki Heavy Industries: 49.9% in 2019, eventually increasing to 100% at the beginning of 2023. Now, Bimota can rely on Kawasaki’s technology supply, including engines, and its sales network.

We started designing the new Tesi H2 right away: carbon bodywork and a supercharged, high-performance engine with the highest category performance, boasting 230 horsepower for the Euro 4 version and 200 for the Euro 5,” confirms Pierluigi Marconi, Bimota’s technical director. “However, we soon encountered an unforeseen obstacle – the Covid pandemic and the need to work from home. It turned out to be an opportunity to change our approach and design the entire motorcycle in 3D, opening up a range of interesting possibilities.”

In the Bimota workshop, the prototype of the Tesi H2.

From 12 to 4 months for the prototype.

Having the 3D model of each part of the motorcycle is undoubtedly advantageous because it allows for virtual testing and evaluating the actual correctness of certain decisions made by the designer on the screen.

However, “there still comes a time when you have to touch the pieces, assemble them, and understand how they behave to determine if the choices made are correct,” adds Marconi. “In the past, it was necessary to manually create clay prototypes, from which rapid molds for fiberglass had to be constructed. A costly and laborious process, whose results were not always precise.

Now, with the 3D files available, we have the opportunity to have them printed through rapid prototyping services: this is how we got to know Prosilas.”

From the idea to the first exhibition mockups, it is possible to reduce the timeline from approximately 12 to 4 months, with a clear reduction in associated costs. Once the validity of the project is confirmed, the production of equipment begins. Marconi continues, ‘The development proceeds very quickly, the fine-tuning of components takes a few weeks, and a 3D-printed prototype is obtained from the file within a couple of days.

We check if the geometries and modifications are correct or if further adjustments are needed. In this case, it is sufficient to send the file back to Prosilas to obtain the new printed piece for testing. Typically, with a couple of iterations, we achieve the best possible result. Previously, mold adjustments were necessary, a very costly activity: at best, it required some modifications, and sometimes even a complete remake.”

Track testing with the Tesi H2

Prosilas’ 3D printing also works on the track.

For a company like Bimota, the result is evident in on-track testing:When you book a test day and organize the trip for some engineers from Japan,” explains Marconi, “you cannot afford a component delivery failure. A test day can cost us tens of thousands of euros, and today, no one is willing to squander such an investment.”

Therefore, it is necessary to find a partner capable of producing even the most complex components, which are challenging to develop solely based on fluid dynamics simulation. The multiple variables at play, such as air temperature or flow direction, make it more practical to design a high-quality 3D file for practical testing on the road

And this is where Prosilas’ rapid prototyping proves reliable and valuable. “Once we designed some body parts and ducts, we obtained the printed pieces in a day and tested them,” explains Marconi. “The use of Nylon loaded with glass fiber (PA12 GF) is ideal in terms of mechanical strength and resistance to high temperatures. Some parts are indeed very close to the exhaust system or radiators and need to endure for a long time, providing us with useful data to understand if we are on the right track. Additionally, it is a material that does not deform, a very useful characteristic when used for the coupling of body parts.”

Tesi H2 marked the beginning of a path entirely dedicated to 3D for Bimota. With the KB4, featuring an appealing Vintage Inspired appearance, Prosilas’ additive manufacturing allowed, for example, the creation of a complex air duct system. TERA, the latest addition from the Rimini manufacturer, stood out at the last edition of EICMA – Milan, thanks to two exclusive kits, which will soon be updated with additional aerodynamic appendages.

The respect for established timelines

For Bimota, the initial experience with 3D printing was not immediately positive. “We had worked with suppliers who sent us deformed components, out of tolerance, some even delaminated,” admits Pierluigi Marconi. ‘So the benefits of rapid prototyping were nullified because if you have to intervene on a piece and it doesn’t perform as expected in tests, you can’t know if the fault lies with the design, the material, or the printing. Also, for this reason, in my opinion, the cost factor is secondary: spending 10% less but having parts that do not meet our expectations means wasting money. The same goes for delivery times: if I cannot rely on a supplier, it means it’s the wrong one. When we met the Prosilas staff, on the other hand, we immediately noticed a great attention to our needs and the challenges of our work.”

Another critical detail is related to timelines: while prototyping allows for a reduction in development times, it also demands that the supply chain be absolutely reliable. Another challenge that Bimota and Prosilas have overcome together. Prosilas is the most accurate and punctual suppliers we have ever had,” concludes Marconi. We provide them with the file, and we get a delivery timeline that is crucial for us, as we base subsequent activities on it.”

A future full of challenges for Bimota

Now that Bimota designs new models in 3D and leverages the additive technology of Prosilas, both the time and cost of the process have undergone a significant reduction. The company remains in constant search of new ideas and solutions to make further advancements in every aspect: from the performance of their motorcycles to the reduction of development budgets, always keeping an eye on overall timelines.

The expertise and guidance from Prosilas experts can once again prove to be the winning strategy to achieve desired results and solidify Bimota’s success in the market
