3D printed car for the race track

3D printed car for the race track

The Shell Eco-Marathon Europe, a fuel-efficiency challenge, took place in Rotterdam in July 2015. Among Polish teams, the Iron Warriors achieved the most fuel-efficient performance. The team highlights the fact that 3D printing was an important factor in their score.

Szymon Madziara from the Iron Warriors said that the low weight yet durable elements 3D printed on Zortrax M200, helped them to reduce the vehicle mass. "By using 3D printing technology we could reduce the weight of the vehicle and boost the score in Rotterdam.

3D printed gear, which is a part of propulsion transmission, is both durable and three times lighter than if we did it with the aluminium. To reduce the mass, we have 3D printed parts for carrying heavy loads, and then cover them with carbon fibre. The effect was fantastic, so we decided to use this technique for our next vehicle - the goal is to score 1,000 km on 1 litre."

The Iron Warriers are not alone in their preference for 3D printing. KU e-Racing of Kingston University, London, used a Zortrax 3D printer to create the model for their car that was later tested in the wind tunnel. The 3D printed model helped in the examination of the air resistance, and so helped the team to determine the shape of the new vehicle. The team was able to improve aerodynamic properties and maximise the downforce on the car which improves the handling of the car.

The vehicle used several parts 3D printed on Zortrax M200 to reduce the vehicle mass and cost. The pedals, housing for telemetry devices and even components for the cockpit to name just a few. The use of 3D printing allows the use of elements specially designed for the project and difficult to obtain.

Both teams believe 3D printing will lead to a revolution in automotive design, providing the possibility to create durable yet low cost parts for a specified shape.
