The DeltaWing Race Car Engine Was Created with Additive Manufacturing

 - Apr 2, 2015
A testament to the practical applications of 3D printing for the automotive industry is that the professional racing DeltaWing uses 3D-printed car parts. The DeltaWing was first debuted at the 24 Hours of Le Mans back in 2012, but it continues to evolve at the same speed as technology.

What really sets the DeltaWing apart is its lightweight body, power and low drag. These features make the car supremely sustainable because it requires less fuel and tire replacements during a race. Engineer Christian Yaeger continues to improve on the design of the car by implementing a 3D-printed intake manifold, the part of the engine that provides air to the cylinders. This component was created in a composite called Windform SP, a polyamide based material that's filled with carbon. Although the shaping of the engine part was a challenge, CAD software was integral to problem solving. As Yaeger says "We could not have made this motor happen if we couldn’t produce parts directly from CAD files."
