We at CAD / CAM Services are amongst the leading lights of 3D scanning and as a matter of fact, consider it to be the very future of CAD / CAM technology as it exists today.

What exactly is 3D Scanning really?

3D Laser Scanning is widely referred to as a process that is not just non-contact but non-destructive as well. As a matter of fact, this 3D scanning technology digitally captures the actual shape of the physical objects per se. For this purpose, it uses a particular line of sight laser light. In this case, the typical 3D laser scanner actively creates a “point cloud” of data that it subsequently lifts from the surface of the object itself.

In other words, we can so say that 3D laser scanning is a great method to capture any specific physical object’s exact size as well as shape and transfer that precious data into the original computer world as a form of digital 3-dimensional representation of the whole.

In fact, if we were to study them a bit more we will realize that 3D laser scanners are fully capable of measuring the fine details and also quite capable of capturing many, if not most free-form shapes so as to quickly and efficiently generate highly accurate point clouds of the same data. 3D laser scanning is widely considered by many industry experts to be ideally suited for both the measurement as well as the inspection of many different contoured surfaces along with their complex geometries that typically require huge amounts of data transfer to be able to give a completely accurate description. They can easily be used when it is deemed highly impractical to use various traditional measurement techniques, such as a touch probe for instance.

The whole3D scanning process

In order to laser scan an object, it has to be first and foremost place on the very bed of the digitizer component. Certain highly specialized software programs also help drive the laser probes over and above the actual surface of the object being scanned. In this case, the real world laser probe projects a thin beam or line of laser light directly onto the surface of the object sitting on the digitizer bed.

At the same time, multiple sensor cameras continuously keep recording the fast-changing distance as well as the shape of the laser line in its original three dimensions (ABC) even as it sweeps aright along the object that is being scanned.

The resultant shape of the real world (physical) object then proceeds to appears as literally millions of points that are colloquially referred to as a “point cloud” on the computer’s monitor, even as the laser moves all around the object capturing the entire surface shape of the object.

We at CAD / CAM services are more than capable of handling even the toughest of 3D scanning chores easily enough.
