Welcome back to our application spotlight series, where we highlight how UltiMaker 3D printing technology powers innovation across industries: from manufacturing and education to high-performance motorsports. Each story shows how additive manufacturing helps teams cut costs, save time, and stay ahead of the competition.
This week, we’re heading to the racetrack in Amersfoort, where a Formula 3 racing team used 3D printing to produce a lightweight, high-performance side pod blower.
Keeping cool under pressure
In motorsport, every component has a role to play in maximizing performance. The side pod blower helps regulate airflow to cool critical systems in the car. Traditionally, manufacturing such a part requires custom tooling and specialist machining—an expensive and time-consuming process that isn’t always compatible with the fast pace of racing.
High-performance parts, printed in-house
By turning to UltiMaker 3D printing, the racing team created a functional side pod blower in-house, combining PET CF for strength and rigidity with TPU 95A for flexible elements. This material pairing delivered the durability needed for racing conditions while reducing both cost and lead time dramatically.
And when iterations were needed? The team could print updated versions directly in the workshop, without waiting weeks for suppliers.
Efficiency gains at a glance
- Cost reduced from ~€700 to just €120
- Lead time cut from 3 weeks to only 1 day 19 hours
- Materials: PET CF for strength, TPU 95A for flexibility
Engineered for speed
The 3D printed blower was optimized for both airflow and fit, ensuring maximum cooling efficiency without adding unnecessary weight. The flexibility of TPU allowed for smoother integration, while PET CF provided the structural stability needed under high stress.
