Description

Michelin has been utilizing laser Powder Bed Fusion since the early 2000’s to manufacture tire sipes used within their tire molds. Sipes for tires are designed to improve road holding on wet or wintery roads, while still allowing the rubber to remain rigid, and maintain these levels of rigidity, when the tire is new or worn. By completely transforming the process used to produce parts, additive changed manufacturing at Michelin. There is no longer any need to go through several preliminary steps, nor assemble different components to obtain the desired part.

Impact & Result

- Achieved a 60% reduction in global environmental impact compared to the previous aluminum casting solution.
- Cut development time from 9 weeks to just 2 weeks, optimizing resource allocation and project timelines.

Solution Spotlight

The Formup 350 by Addup is an additive manufacturing production machine using the Laser-Powder bed Fusion (L-PBF) technology. A powder bed is locally melted by 4 lasers, drawing on the surface the slice of a part. This routine is repeated consecutively until the height of the part is reached. Our 3D metal printer offers three recoating systems (Brush, roller, silicon blade) allowing unique flexibility to customers and maximizing the reach of the metal 3D technology. FormUp 350 machines are safe, efficient, and scalable, integrating more than ten years of experience built by AddUp and Michelin in PBF technology, with safety at the heart of our concerns.
