BMW E36 Baur Sunroof Fabrication – Restoring a Rare Classic

This BMW E36 Baur sunroof fabrication project involved 3D scanning, reverse engineering, CAD design, and custom manufacturing to recreate an extremely rare discontinued automotive component.

With only 321 BMW E36 Baur vehicles ever produced worldwide, sourcing original replacement parts is practically impossible today.

Recently, we were contacted by a client who needed a sunroof solution for his BMW E36 Baur. Since no original replacement parts were available anywhere on the market, the only realistic option was to recreate the part from scratch using modern 3D scanning and 3D printing technologies.

3D Scanning the BMW E36 Baur Roof

To ensure maximum accuracy, we traveled directly to the client with professional 3D scanning equipment. The first step was digitally scanning the vehicle’s roof geometry and surrounding mounting areas.

Using high-precision 3D scanning allowed us to capture:

• Exact roof dimensions
• Mounting locations
• Curvature and contours
• Factory fitment tolerances

This process is essential when reproducing rare automotive components, especially for vehicles where OEM documentation and replacement parts no longer exist.

Designing the Custom Sunroof

Using the 3D scan data, the part was reverse engineered inside CAD software to ensure OEM-style fitment and accurate alignment with the original roof geometry.

The goal was clear:

• Maintain OEM-style fitment
• Replicate the original appearance
• Ensure reliable installation
  

Every detail was carefully modeled to match the factory design as closely as possible.

3D Printing the Replacement Part

Once the design phase was completed, the sunroof component was manufactured using advanced 3D printing technology.

This approach offers several major advantages for rare automotive restoration projects:

• No need for unavailable OEM parts
• Fast prototyping and adjustments
• High dimensional accuracy
• Cost-effective low-volume manufacturing

For ultra-rare cars like the BMW E36 Baur, additive manufacturing has become one of the most effective ways to keep these vehicles on the road.

Final Result

The final result exceeded expectations. The newly manufactured sunroof fit the vehicle just like the original factory component.

The client’s problem was fully resolved, and another rare BMW was successfully preserved using modern reverse engineering and 3D printing technologies.

The custom BMW E36 Baur sunroof replacement panel is now available through our store for restoration and custom fabrication projects.
