Reconstruction of Replacement Parts for Classic and Vintage Cars
Welcome to Oldtimerparts! We rely on state-of-the-art technologies to digitize and manufacture spare parts for classic cars. Our goal is to precisely map the geometry of spare parts in digital models to enable efficient reproduction. In this article, we give you an insight into the different methods of digitization.

Digitization
How to get a digital model?
In digitization, the physical spare part is converted into a digital model. This means that the shape and dimensions of the part are recorded on a 1:1 scale. They are then represented in CAD software, creating a digital replica of a real component.
This process forms the basis for 3D printing and takes place only once. Basically, there are two methods.
- CAD construction
- 3D scan

Digitization
CAD construction
CAD construction enables digitization by measuring spare parts and recording them in CAD software. The resulting digital file contains all dimensions, geometry, and positional information.
Even defective parts, such as cracks, breaks, or deformations, can be digitally reconstructed if the original shape and structure are still recognizable.
Through our spare part request, you can request a custom construction task. We will be happy to advise you and provide a cost estimate.
The first step in the reconstruction is the measurement of the component, followed by the selection of an appropriate digital imaging strategy. Every detail is recorded using special CAD programs, which create a CAD model step by step.
This model can then be exported in various formats, with the STL format being predominantly used in 3D printing. You can find more information in ourBlog.
This construction method can also restore defective components.

Digitization
3D scan
As a second reconstruction method, there is the 3D scan. Unlike CAD construction, the component is not measured but captured optically.
Spare parts with complex geometries and multiple different freeform surfaces, as well as curved shapes, are very difficult to capture through CAD construction.
Here, 3D scanning offers a possibility for digitization.
The spare part is scanned optically using a laser and captured from all sides by the scanner. In 3D scanning, a point cloud is first created, capturing the contours and shapes of the part.
