Japanese automaker Toyota is the first to use HP‘s Multi Jet Fusion 3D printing technology to produce a production part for the Lexus LC500 luxury sports car. The printed part is an oil cooler duct that is offered as an accessory.
The part was developed and manufactured by technology service provider SOLIZE. Toyota and SOLIZE have been working in partnership on 3D printing of replacement parts since 2021. Now SOLIZE is registered as an approved supplier for Toyota.
The printed oil cooler duct is designed to prevent automatic transmission oil from overheating during circuit driving. According to Toyota, smoother gear changes and more driving comfort can thus be achieved.
Extensive material and pressure tests were conducted during development to achieve robust properties. In addition, Toyota and SOLIZE optimized design and layout for cost-effective manufacturing. Compared to conventional manufacturing, greenhouse gas emissions were reduced by 37 percent, according to SOLIZE.
Before being approved as a supplier, SOLIZE had to establish management systems for the environment, processes and employee training. Toyota sees additive manufacturing as a way to avoid costly mold-making tools and inventory in the future.
The oil cooler duct is the first time Toyota has introduced an approved production part from the 3D printer. This underscores the company’s confidence in the maturity of the technology for automotive production. SOLIZE was able to position itself as a partner with the necessary know-how.
