Optical 3D scanning &
CT Scanning Services
For everyone who needs a digital twin of their object
Optical 3D scanning &
Capture the smallest details
Our scanning systems are specifically chosen for quality and the best possible data. With a resolution of up to 0.01 mm, they are capable of capturing even the smallest details.
If your products or objects contain small features like tiny holes or mould split lines, no worries we can scan it. Over the years we have developed special procedures for dealing with small objects so that we can capture the necessary data for your application.
Metrology grade accuracy
ACCURACY and PRECISION is part of our DNA as we strive for perfection in everything that we do.
We make exact digital twins of your products. Therefore we only use state-of-the-art Optical and CT Scanning systems in our metrology lab. This way you can rely on the data that you get from us.
We deliver 3D scans suitable for Dimensional Quality Control, Reverse Engineering and 3D printing
Our systems are certified according to the international VDI/VDE 2634 norm.
CT Scanning Services
Measure the invisible
Are your objects very complex and/or contain hidden features ?
With our CT Scanning Services we are able to scan these hidden features which cannot be reached with other scanning systems.
We can even measure internal defects like porosity or inclusions.
Any Size
Thanks to the modularity of our systems,
we are able to scan objects of different sizes.
Ranging from 1 mm, up to 5 m!

FAQ
Why TetraVision?
At TetraVision, we like to think together with our clients, to clearly understand your needs so that we can provide the most adequate solution and file format.
We have years of experience using all sorts of 3D scanning systems.
We also believe in service of the highest quality and will make sure that you are helped in a timely and professional manner.
If for a reason we think that one of our scanners is not the best suitable for the job,
then we will inform you and bring you in contact with one of our partners.
We have a great network of trusted partners with complementary equipement.
Scanning at your facilities?
Smaller objects that are not too heavy can easily be transported to our office and we ship them back afterwards.
For big objects that cannot be transported we also have the possibility to do the scanning at your facilities.
Extra transportation costs do apply based on the travel distance etc.
Wat is the accuracy of the scans?
Our scanners are certified according to the international VDI/VDE 2634 part 3 norm. This norm certifies the scanner against a calibrated artifact. We can provide the certificate on request.
The following rule of thumbs can be applied to estimate the measurement accuracy:
For parts:
- < 50 mm: about 0,005 mm or better
- < 150 mm: about 0,008 mm or better
- < 300 mm: about 0,016 mm or better
- < 550 mm: about 0,028 mm or better
- < 700 mm: about 0,035 mm or better
- > 1500 mm: about 0,035 mm + 0,015mm/m or better
The exact achieved accuracy depends on multiple factors like the part geometry, the part material, the part flexibility, the measurement environment (when on-site) and measurement setup.
When the application requires it, we perform a MSA (Measurement System Analysis) to determine the exact system performance, on a specific part. We often ends up with better results than shown in this table.
What is the resolution of the scan? What is the smallest feature you can measure?
The resolution depends on the part size as well.
We can achieve the following resolutions for objects:
- < 50 mm: up to 0,012 mm resolution, or about 83 points / mm
- < 100 mm: up to 0,031 mm resolution, or about 32 points / mm
- < 150 mm: up to 0,065 mm resolution, or about 15 points / mm
- < 300 mm: up to 0,112 mm resolution, or about 9 points / mm
- < 550 mm: up to 0,176 mm resolution, or about 6 points / mm
- > 700 mm: up to 0,212 mm resolution, or about 5 points / mm
What is the file format ?
The standard output of a 3D scan is a .STL file. It is a mesh built out of small triangles.
We can export it as well as a .G3D, .POL, .PLY, .OBJ, .3DS, .WRL or .JT file.
After reverse engineering, we can deliver a CAD file with these file formats: .IGES, .STEP, .X_T or .X_B file (Parasolid)
Please check our reverse engineering service for more info as this involves an extra step and costs after 3D scanning.
How can I open the file?
Usually you can open .STL files in your native CAD software.
Depending on this software you might have limited options to process the scans.
If your own software doesn’t allow you to open the files, you can use the free GOM Inspect viewer
This software can be downloaded here (https://www.gom.com/3d-software/gom-inspect.html).
