Transformative Advances in Automotive Manufacturing
MacLean-Fogg Company and Fraunhofer Institute for Laser Technology ILT are setting the stage for revolutionary changes in the automotive sector with their cutting-edge innovation. They have successfully created the world’s largest nearly solid die casting tool insert made from 3D printing. This remarkable achievement weighs 156 kg (350 lbs) and is designed for the Yaris hybrid transmission housing.
Innovative Solutions Through Additive Manufacturing
The partnership between MacLean-Fogg and Fraunhofer ILT opens doors to unprecedented tooling solutions that promise shorter lead times and improved durability in manufacturing processes. Through the use of advanced additive manufacturing techniques, the companies aim to meet the evolving needs of the automotive industry.
A Landmark Achievement in Tooling
The innovative insert was manufactured using Fraunhofer ILT's state-of-the-art multi-laser Laser Powder Bed Fusion (LPBF) technology. This process employs MacLean-Fogg’s proprietary L-40 tool steel powder, which is crafted specifically for additive manufacturing, ensuring optimal performance and reliability.
Pushing Boundaries in Production Technologies
MacLean-Fogg’s L-40 powder showcases remarkable hardness and toughness, significantly reducing issues like crack formation during the printing process. This enhancement leads to decreased needs for post-build heat treatment, thus expediting product delivery to the market.
Highlights of this advancement include:
- Enhanced lifespan of tooling, doubling the durability compared to traditional aluminum inserts.
- Notable reduction in maintenance demands.
- Commitment to sustainability, as the material avoids cobalt and minimizes nickel content.
Collaboration with Toyota Europe
Dr. Magdalena Coventry and Dr. Andrew Willett from Toyota Europe have expressed their enthusiasm for the partnership, recognizing the potential to streamline production with this innovative approach. They believe that this collaboration can elevate the efficiency of metal 3D printing in meeting demanding specifications while keeping costs manageable.
Advancements in Laser Technology
Fraunhofer ILT’s five-laser LPBF system is at the forefront of this revolutionary process, capable of handling larger components while maintaining accuracy. This system enables the production of inserts over 50 cm in dimension, which is key to fulfilling the requirements for large-scale automotive tooling.
Future Directions in Manufacturing
This collaboration looks to expand into structural die casting applications, targeting larger hot or cold forming tools traditionally underserved by conventional materials. This move aligns with trends in the automotive industry to enhance efficiency, reduce weight, and solidify supply chain resilience.
