If you restore classic cars, you already know the hardest part is rarely the paint or the engine rebuild — it’s finding that one discontinued trim piece, bracket, or knob that hasn’t been manufactured in fifty years. 3D scanning for classic car restoration solves this problem by turning an original part, even a broken or worn one, into an accurate digital model that can be remanufactured. At our Glendale studio, we’ve spent over two decades helping restorers, custom builders, and collectors across Los Angeles bring obsolete parts back into existence.
How 3D Scanning for Classic Car Restoration Works
The process starts with the physical part — or what’s left of it. Using laser and structured light scanners, we capture millions of surface points to build a precise digital replica. For larger components like body panels or dashboards, photogrammetry can supplement the scan data.
A raw scan is only the first step. The scan mesh is then converted into a clean CAD model through reverse engineering, where we rebuild the part’s true design intent: restoring symmetry, sharpening worn edges, and correcting damage. If a part is cracked or half-missing, we can mirror the intact side or reconstruct the geometry from reference photos and measurements. The result is a manufacturable file, not just a digital snapshot. You can read more about our capabilities on our 3D scanning service page.
What Parts Can Be Reproduced?
Almost anything that unbolts from the car can be scanned and reproduced. Common requests we see include interior trim pieces, knobs, and switch bezels; emblems, badges, and grille components; brackets, clips, and mounting hardware; dashboard components and vent housings; lenses and light housings; intake components and carburetor parts; and side mirrors and exterior trim.
Chrome and highly reflective parts scan poorly in their raw state, but a light temporary matting spray solves that without harming the finish. Even heavily pitted or corroded parts usually retain enough geometry to reconstruct.
From Scan to Finished Part: Your Manufacturing Options
Once a clean CAD model exists, there are several paths to a physical part.
3D Printing
For prototypes and many end-use parts, 3D printing is the fastest route. SLS nylon works well for clips and brackets, SLA resin captures fine detail on trim and emblems, and DMLS metal printing can produce functional metal components directly.
Casting and Machining
The CAD model can also drive traditional manufacturing — CNC machining for billet aluminum parts, or investment casting when you need the part in the original alloy. For decorative pieces, a printed master can be used to cast metal parts that are then plated or polished.
Small Production Runs
If you run a restoration shop and need the same obsolete part repeatedly, one scan becomes a permanent digital inventory. We can produce parts on demand, so you never hunt swap meets for that component again. Our product design team can also adapt the design — strengthening a known weak point or updating a mount for modern hardware.
What Does It Cost?
Every part is different, but as a rough guide: scanning and reverse engineering a small-to-medium part typically runs a few hundred dollars, with complex assemblies or large panels costing more. Reproducing the part adds printing, machining, or casting costs on top. Compared with months of searching for NOS (new old stock) parts — or paying collector prices when one finally surfaces — digitizing the part is often the more economical path, especially when you factor in that the digital file never wears out.
Why Work with a Local LA Shop?
Classic car parts are exactly the kind of project that benefits from being handled in person. You can bring the part to our Glendale facility, we can evaluate it on the spot, and you avoid shipping an irreplaceable original across the country. Being local also means faster iterations: if a test-fit print needs a tweak, the revised part can be in your hands in days.
