【3D Printing】FORZE Hydrogen Racing Team Integrates 3D Printing into Hydrogen Prototype Development
The Forze racing team, managed by 45 student volunteers, is dedicated to developing the hydrogen-powered Le Mans prototype, Forze 9.The team participates in the Supercar Challenge in the Benelux region, committed to advancing clean energy in motorsports, with a particular focus on hydrogen-powered vehicles.
With limited resources and tight deadlines, the team adopted 3D printing as a key technology to accelerate their prototyping, manufacturing, and iterative design processes.
The integration of 3D printing allowed the team to quickly create and refine parts, optimize designs, and adapt to the unique challenges of building a hydrogen-powered race car.
This approach not only expedited the engineering cycle but also enabled the team to experiment with designs.
Building a Champion
As a student-managed team, Forze faces many challenges, including a limited budget and difficulties in accessing external manufacturing services.
Traditional methods, such as CNC machining, meant longer lead times and high costs.
Given the complexity of developing hydrogen-powered vehicles, rapid prototyping is crucial for dynamic testing, iteration, and refining key components, especially to ensure proper fit and function.
The Method XL 3D printer has become central to the Forze team's workflow.
With its dual extruder system, large build volume of 305 x 305 x 320 mm, and user-friendly features, it allows the team to quickly and efficiently print prototypes while ensuring high-quality and reliable parts for critical systems of their vehicle.
This printer has increased the integration between different vehicle components, enabling the team to rapidly test parts, check fit, and even detect potential issues before they impact larger assemblies.
This enables the team to create prototype parts that are both light and strong, which is crucial for extreme environments.
The team primarily uses ABS for prototyping due to its durability and ease of use, while carbon fiber is employed for high-strength applications like structural components.
Water-soluble support materials dissolve easily and quickly in warm water, making them ideal for more complex parts that require intricate geometries without support structures.
While PLA is available to the team, it is generally used for smaller, non-critical parts.
3D printing has significantly shortened prototype development time.
What used to take weeks in traditional manufacturing processes now takes only hours, allowing the team to receive immediate feedback and refine designs more quickly.
Impact of 3D Printing on Team Collaboration
The adoption of 3D printing has led to a shift in how the team works together.
What started as curiosity about using a single printer for prototyping has now evolved into widespread adoption across multiple departments.
The team quickly learned how to leverage the technology for more efficient design iterations and production, making it a critical part of daily operations.
While the printer is user-friendly, the team also dedicated time to learning slicing, material properties, and post-processing techniques.
Knowledge is shared within the team, with more experienced members supporting those new to 3D printing.
There's even an internal "admin" role responsible for managing the digital factory platform and resolving more complex issues, such as material-specific challenges.
"We've learned a lot in the process," says mechanical engineer Ernst Paardekooper.
"We have a pipeline for 3D printing, and when others get stuck, those with more experience in slicing materials help them.
Although the printer is intuitive, some things, like material settings, can be difficult to get right at first.
For students like the Forze team, 3D printing provides valuable hands-on experience that can directly benefit their future careers.
The ability to rapidly prototype, iterate designs, and solve problems equips students with practical, industry-relevant skills highly sought after by employers.
These experiences can help prepare students for positions in industries such as automotive, aerospace, and consumer goods, where rapid prototyping and product development cycles are key.
Future Expansion Plans
As the Forze team's work continues to evolve, they look forward to increasing their use of 3D printing.
The printer's ability to handle larger builds and complex designs opens up opportunities for 3D printing more components, including structural parts and custom fixtures.
"We've printed a lot of things by now, and as we continue to iterate, we will likely increase our use of 3D printing," says Chief Chassis Officer Koen Vogels. "Having a reliable and easy-to-use printer has already given us an advantage. It allows us to experiment with new ideas quickly and effectively.
Competitive Advantage
3D printing has become an essential tool in their development of hydrogen-powered vehicles, while also providing them with indispensable skills for their future careers.
Many engineers now need to know how to use 3D printing in product development, and teams like Forze offer students the chance to cultivate these skills in a real-world environment before graduation.
