X-ray CT scanning technology is used to reconstruct the volume of a workpiece (3D point cloud) using X-ray image projections of the object.
Our X-ray technicians can inspect your workpieces using this non-destructive inspection technology (porosities, cracks, inclusions, internal defects, leak detection, fibre visualisation, etc.), and measure workpieces (plastic and aluminium) with a precision of 10+L/50 (or approximately +-12µm).
“If you would like to perform in-house workpiece post-processing, you also have the option of forwarding a 3D scan of your workpiece to us and getting in touch with our teams.
VG studio max volume graphics software is available to purchase; please feel free to ask your point of contact for more details.”

Aims:
– Obtain the CAD file for a workpiece for which plans are not available or for which you need a file quickly (e.g. prototype).
– View and compare workpiece form errors compared to the nominal CAD file.
– Analyse mould deformations according to wear over time or a change of material.
Step 1: Workpiece 3D Digitisation / Scanning
This process allows you to scan your workpieces to generate a “point cloud” digital model.
Our 3D digitisation resources
We can provide this service with several specialised tools based on workpiece type:
• CT scanning (in air-conditioned laboratory at 20°C).
Used for small-size workpieces requiring high precision, this tool can also be used to digitise internal workpiece surfaces using X-rays. In fact, given that the CT scanner scans the entire workpiece, we can thus access even the most inaccessible surfaces.
• Scanning measurement arm.
Used to model workpieces from a few centimetres to several metres.
This mobile equipment is suitable for use in our laboratories and/or on-site.
• Laser tracker coupled with scanning system.
Used for models of several metres.
This mobile equipment is suitable for use in our laboratories and/or on-site.
Step 2: Reverse engineering
Also known as 3D reconstruction, this step consists of using the digitisation from step 1 to output files compatible with CAD or 3D printing software.
– 3D printing from file in STL format (raw digitisation format)
– CAD reconstruction into multiple recognised formats such as STEP, IGES, CATIA, CREO, SOLIDWORKS, FUSION360.
