Windform 3D printing composite materials from CRP Technology have been utilised in the development of the Deltawing race car, which has been designed to perform at the same level as other Le Mans prototype vehicles but with half of the available horsepower.

At the design level, this meant the car could only have half the mass and half the drag of the normal race vehicles.

To make the car work, an extreme weight-loss programme was initiated. However, time was very short, with only seven months from design to first track test.

The team used 3D printing technology together with Windform high-performance materials where applicable to speed up manufacturing time and to save as much weight as possible.

Key information

  • Laser-sintered Windform XT 2.0 was used in tooling, prototyping and testing, in areas including brake inlets and ducting, air inlet ducting, filter enclosure and the BLAT (underbody extension flange).
  • It was also utilised in mission-critical applications on the car, including bespoke electronics enclosures, electrical breakout boxes, transmission seal covers with integrated pressurised oil feed passages and the tow hook plinth.
  • Windform XT 2.0 was also used to construct the gearbox side covers.
  • Deltawing engineer Zack Eakin said the fact that Windform XT 2.0 could be used as a raceable part at the elevated temperatures and pressures the gearbox oil is run at opened up design possibilities that previously would have been too expensive in both time and cost.
  • The use of 3D printing and Windform materials were fundamental to shortening the timing of car construction.
