CT and Reverse Engineering for Industry
It’s now possible to completely digitise any industrial objects in 3-dimensions with Computed Tomography.
By using X-Ray technology and multiscale acquisition, CT (and microCT) is a very efficient tool to model manufactured parts, casts, assemblies, components.
After X-ray acquisition process, the 3D reconstruction of Digisens directly render the model in 3D voxels (volume rendering). The SRF plugin of the software suite DigiCT provides surface rendering capabilities from the reconstructed 3D CT volume rendering. 3D surface models can be saved in CAD compatible format such as STL, IGS or cloud points.

3. Surface rendering (triangles)
The surface is determined with a grey-scale isovalue, and a texture is automatically generated on the surface.
It’s possible to render the objet in semi-transparent mode. It highlights the eventual defection (air inclusion, porosity) and internal geometry as well. 3D model real time cross section is also possible.
3D surface model can be represented in wire frame mode. From a 256x256x256 voxels microCT volume, an approx. 600000 faces surface model is generated. This can be up to 5 millions faces.
A surface optimisation option is also included in SRF plugin of DigiCT. Then user can easily low wireframe number to optimise CAD file size.
Surface with 436 000 faces
Surface with 24 000 faces
SRF plugin is user friendly and efficient for object scanning, Reverse Engineering, and Rapid Prototyping as well. From a 3D CT volume or a 2D CT slices series, a complete 3D surface model can be computed and stored in STL, OBJ, IGS, cloud points...
