3D Printing for Race Cars: Enhanced Cooling Efficiency

Race Car Cooling System

Small University Race Car with LED lighting

Monash Motorsport, Monash University’s premiere Formula Student team, in collaboration with Formero, needed to improve the cooling efficiency of their race car engines. Utilising Formero’s expertise in 3D printing for race cars and the wide range of materials available, custom cooling solutions were developed to ensure the motors operated at optimal temperatures during high-performance racing.


Monash Motorsport needed to prevent potential overheating in their race car motors and inverters during intense racing sessions. The challenge was to create durable, heat-resistant parts that would not only manage thermal loads effectively but also provide strain relief and waterproofing for sensitive electrical connections.

Formero suggested that the motorsport team implement Selective Laser Sintering (SLS) technology to manufacture the bespoke cooling jackets and motor shrouds from nylon PA-12. This material was chosen for its excellent thermal and mechanical properties. The SLS process enabled the creation of complex geometries essential for efficient cooling. Additionally, Formero implemented Z-bonding techniques to enhance the structural integrity and durability of the 3D printed parts.

  • Material Selection: Nylon PA-12 was selected for its thermal resistance and mechanical strength, crucial for the high-performance environment of race car engines.
  • 3D Printing Process: SLS technology allowed for the precision manufacturing of parts with intricate designs that traditional methods couldn’t achieve.
  • Z-bonding: This process improved the overall strength and durability of the printed parts, ensuring they could withstand the stresses of racing.


The custom cooling jackets and motor shrouds significantly improved thermal management for Monash Motorsport’s race cars. These enhancements prevented potential overheating, ensuring the motors maintained safe operating temperatures. The improved cooling efficiency contributed to better reliability and performance, giving Monash Motorsport a competitive edge in racing events.
