Application Spotlight: Lead Time of Automotive Upright Reduced From 4 Days to 4 Hours with Metal Additive Manufacturing

Why It Matters

Cutting lead times and weight without sacrificing strength gives suppliers a decisive edge in fast‑moving automotive supply chains, accelerating time‑to‑market for new models.

Key Takeaways

• Additive manufacturing cut lead time to four hours
• Part weight reduced via topology optimization
• CDS platform integrates design and manufacturability analysis
• Traditional casting required four days per part
• Supplier maintained structural performance after redesign

Pulse Analysis

Additive manufacturing (AM) is reshaping automotive component production, offering designers the freedom to create complex geometries that traditional casting cannot achieve. However, the transition often stalls due to lengthy redesign cycles and uncertainty about how AM compares to established processes. By slashing the suspension upright’s lead time from days to hours, the tier‑1 supplier proved that AM can meet the industry’s demand for rapid iteration, especially for high‑performance vehicles where weight savings translate directly into efficiency and handling gains.

The breakthrough stemmed from Cognitive Design Systems’ integrated platform, which consolidates topology optimization, material selection, and manufacturability analysis into a single workflow. Engineers no longer toggle between disparate tools, reducing manual hand‑offs and the risk of data loss. This concurrent engineering approach accelerates decision‑making, allowing the supplier to evaluate multiple AM pathways—such as powder bed fusion and directed energy deposition—side‑by‑side with conventional casting. The result is a data‑driven redesign that trims excess steel, meets load requirements, and shortens production cycles without additional tooling costs.

For the broader automotive ecosystem, the case signals a shift toward more agile, digital‑first supply chains. OEMs can now expect suppliers to deliver lightweight, high‑strength parts on demand, supporting rapid model updates and low‑volume specialty builds. As platforms like CDS become commonplace, the barrier to entry for AM diminishes, encouraging wider adoption across chassis, powertrain, and interior components. Companies that embed such capabilities early will capture cost savings, improve sustainability metrics, and gain a competitive advantage in an increasingly fast‑paced market.
