This long-term investment reflects Audi’s foresight into the transformative potential of 3D printing. Over the years, this facility has accumulated a comprehensive array of polymer 3D printers, encompassing various technologies, including FDM (Fused Deposition Modeling) for strong functional parts and existing PolyJet systems for detailed visual prototypes. These machines have been instrumental in enabling Audi’s engineers and designers to rapidly iterate on different prototypes before a vehicle enters its final production phase.

The existing 3D printing infrastructure has allowed Audi to evaluate a vast range of design concepts and functional prototypes, from intricate wheel covers and distinctive grilles to ergonomic door handles and dashboard components. The integration of the Stratasys J750 marks a significant evolution in this capability, pushing the boundaries of what’s possible for realistic design verification. By adding the J750 to their robust lineup, Audi specifically targets the production of highly detailed, multi-colored, and transparent parts that were previously challenging or impossible to create with such fidelity and in a single step. This includes, but is not limited to, critical components like intricate taillight cabochons, which are crucial for a vehicle’s aesthetic appeal and safety signaling.

Transforming Taillight Cabochon Production: Unprecedented Speed and Precision

One of the most compelling applications of the Stratasys J750 within Audi’s workflow is the streamlined production of taillight cabochons. Traditionally, these complex components, vital for both vehicle aesthetics and functional lighting, are designed and manufactured through a laborious multi-step process.
