The 3D scanning of an object in the industrial field can have a double utility: acquire the 3D geometry of an object to use it in a software environment or check the physical product by comparing it with the 3D geometry that generated it.
Our ATOS CORE 300 three-dimensional optical scanning system from GOM uses Blue Light technology to scan the geometry of physical objects. Thanks to its system of stereoscopic cameras, it digitizes images in real time to return a 3D file that can be worked in any CAD application.
Its stability sensor recalibrates the system automatically, making it particularly suited to production contexts and two specific main applications:
Digitalization of a physical model and three-dimensional reconstruction in CAD: accelerates product innovation by starting from an existing model. The system obtains:
- Point cloud and structural mesh
- Mathematisation of the data acquired
- .STL file for prototypes production
Metrological non-destructiveinspection of components and devices: software performs a comparison with the original CAD model and creates a report highlighting with a colour scale the following:
- Global deviations from the CAD model
- Specific deviations from the CAD model
- Integrated measurements and analysis
Following are the main features of the ATOS CORE 300 system:
- Measurement volume: 300x230x230 mm – larger dimensions measurements can be made in various sections
- Dimensional accuracy: 0.01 mm
- Distance accuracy: 0.05 mm
Frequently Asked Questions
Is there is a maximum size of objects that can be scanned?
The maximum measurement volume for a single scan is 300x230x230mm. However, larger objects can be scanned in several sections.
How long does it take to scan?
A single scan takes only a few seconds, but the total duration of the process depends on the size of the object and complexity of forms, because, when combined, each individual scan must include at least three markers from the previous scan.
Can transparent or glossy parts be scanned?
Yes, but first they will need to be covered with a titanium oxide based spray that renders them matte and opaque and visible to the scanner.
Is the spray used on objects permanent or damaging to them?
No, the powder can easily be washed away with water and can be used on any material, except skin.
Can black objects be scanned?
Yes, simply by increasing the scan exposure time or by spraying.
Can I modify the scanned part?
Of course, once the object file has been acquired, it can be modified at will.
Is it possible to compare the object with my 3D image?
Yes, with the software we use, we can superimpose our scan, or mesh as it is often called, on the 3D image, preferably in .stp or .igs format, and, via an analysis of the surface, we can obtain a colour map that, at a glance, shows the product’s mathematical correspondence.
What if I have a very large object that I cannot easily move?
Our equipment is portable, so we can come to our customer if necessary.
What degree of accuracy can be guaranteed?
The system guarantees a dimensional accuracy of 0.01mm and a distance accuracy of 0.05mm.
What is the output of the scanning process?
The first output of the scanning process is a point cloud that the software gives in .stl format. This is then processed to give the customer fully workable 3D files for any CAD environment.
Can you help me digitize and renew an old product that I don’t have the original 3D data for?
Our system of reverse engineering is ideal for this purpose. After acquisition of the physical form of the object and creation of its 3D CAD files, you can modify its surface at will. This is a process that we can take care of according to the every need of our customer by leveraging the synergy of our design team just as an outsourced design studio.
Can I scan parts of my production line and then reproduce them accurately?
Of course, the file from the scanning process replicates the physical object entirely. If you do not need to modify it to meet new standards, then it is all ready for the creation of a prototype or mass production, in either plastic or metal.
How can I be sure that the part corresponds perfectly to the original design, at least within a certain tolerance?
Optical scanning is ideal for quality assurance and industrial metrology. Our software allows us to compare the file obtained by scanning with the original file from which the prototype or injection moulded part derive. A chromatic scale is used to display the areas within a certain tolerance and any measured deviations and to provide a final fully detailed report.
