3D Scanning Service

The accuracy depends on the size of the object to be scanned and the scanning technology used. Our structured blue light scanners achieve a measurement uncertainty of 0.01 mm to 0.05 mm and are the most accurate for precision parts. Laser line scanners offer a measurement uncertainty of ± 0.02 mm + 0.015 mm/m and are particularly suitable for medium to large parts. Our tracking system achieves a measurement uncertainty down to ± 0.025 mm over distances up to 8.5 m. For parts smaller than 50 mm, we achieve an accuracy of approximately 0.005 mm or better. Our scanners are certified according to the international VDI/VDE 2634 Part 3 standard. See our FAQ for a full overview per object size.

The standard output is an STL file (mesh built from triangles). We can also export to G3D, POL, PLY, OBJ, 3DS, WRL, or JT. Do you need a CAD file in STEP, IGES, or Parasolid? Then an additional reverse engineering step is needed where we convert the scan to an editable CAD model.

Yes. In addition to our measurement lab in Boutersem, we have various mobile scanners for on-site measurements, ranging from small handheld 3D scanners to very large tracking systems. This is ideal for large objects that cannot be moved, production lines that are temporarily shut down, or parts in the automotive and mechanical engineering sectors.

With optical 3D scanning, we capture the external geometry of an object. Within this, we use different technologies: structured blue light for maximum accuracy on precision parts, laser line scanners for fast and mobile measurements, photogrammetry as a basis for large structures, and tracking systems for real-time wireless measurement over large distances. X-ray CT scanning goes a step further: it also maps the internal structure, such as porosity, internal defects and hidden features. CT scanning is non-destructive and delivers 100% data, both internal and external.

We also frequently use CT scanning when, for example, we only need to scan the outside of plastic parts. The major advantage is that we can scan multiple samples simultaneously. Our experience is that when we can combine 4 parts in 1 scan, CT scanning becomes cheaper than optical scanning. With, for example, 100 samples at once, CT becomes unbeatable in terms of price.

Depending on your part and specific question, we advise which method is most suitable.

Yes. Thanks to our automated measurement cell and specific fixtures, we can scan multiple parts simultaneously. With CT scanning, we can often scan multiple objects together in 1 scan as well. This makes series measurements cost and time efficient. Think of golden samples, pre-production inspection, SPC measurements, and final inspections. Also visit our quality inspection page for more information about measurement reports and inspection options.

Our standard lead time for a 3D scan is approximately 5 working days. Depending on the complexity of the project and any accompanying reporting, this may vary. Contact us for a concrete estimate, we always respond within 24 hours.

The price depends on the type of object, the desired accuracy, the number of pieces, and any additional services such as reverse engineering or a detailed measurement report. We create a customized quote for each project. Request your quote here, you will receive it within 24 hours.

The applications are broad. You can use the scan data for quality inspection (actual-to-nominal comparison, GD&T analyses), reverse engineering (conversion to CAD model), 3D printing, product validation, or visual inspection. We also always provide a free ZEISS Inspect viewer file so you can view the results in 3D yourself.

Yes. TetraVision has held an ISO 17025 accreditation since late 2023, granted by BELAC (Belgian Accreditation Body). This guarantees that our measurement results are reliable, accurate, and traceable. ISO 17025 goes beyond ISO 9001: it also assesses the technical competence of our lab and our measurement technicians.

Our 3D scanning service is used in various sectors, including automotive, healthcare, packaging industry, additive manufacturing, and injection molding. Whether it’s a single prototype or series production, we adapt our approach to your specific situation.

Optical 3D scanners work excellently on most materials and surfaces. Transparent, highly reflective or very dark surfaces pose a challenge, because the light is not reflected correctly.

This is especially the case for structured light scanners, but less so for laser line scanners.

Should it still be a problem, the solution is straightforward: a scanning spray applies a thin, temporary layer that ensures optimal reflection.

For parts with hidden or internal geometry that is not optically accessible, we switch to X-ray CT scanning or work with a plastiform cast.

Every part and every application requires a different balance between accuracy, speed and range. We scan a small precision part with our structured blue light scanners for maximum detail. A large industrial structure is tackled with a tracking 3D scanner. By choosing from multiple technologies, we find the most efficient approach for every project.
