CT Scanning Offers Analytical Benefits Over 3D Modeling Services
ATS now provides CT scanning services – it's like 3D scanning, but better

Often when a critical part fails in a piece of equipment, it is not immediately apparent why. In these instances, companies turn to failure analysis services to gain an understanding of what went wrong. One of the most effective methods for initially determining a part’s cause of failure is to model it with 3D scanning. The tester can examine and manipulate these models with greater ease and in more ways than the physical test sample. Finding surface flaws is easy when comparing the 3D scan of the part to its CAD model, and measuring those flaws with an exact precision is possible due to computer assistance. These features make 3D scanning services very attractive to industrial businesses for not only failure analysis, but metrology and preventative maintenance efforts as well.

Shortcomings of 3D Scanning

There are, however, certain limitations to this process: parts can have internal components which may have contributed to the part failure, the structural flaws may not be visible on the surface, or voids may exist within the surface material itself. 3D scanning cannot pick up on any of these issues on its own, and not all specimens can be subjected to destructive testing. Computed Tomography (CT) scanning addresses these concerns, proving more useful than 3D scanning in these scenarios.

The Case for CT over 3D

CT scanning takes a series X-rays of the test material from various angles. These grayscale projections show a cross-sectional view of the test material as if it had been cut perfectly in half, allowing engineers to look inside without dismantling the part. The imaging is precise enough to show and measure microscopic structural flaws – either outside or inside of the test material. All of the projections can be assembled to create an X-rayed 3D model of the test material, which allows engineers to easily view and scale the model of the internal components for closer analysis. Engineers may then put together a 3D simulation of the part performing its function, and view the stresses and pressures exerted on internal components in an actual use scenario. Computed Tomography combines the insight yielded by older radiography methods and the versatility of scanning a 3D model into one multifaceted testing service.

One of the most compelling points in CT’s favor over 3D scanning is the comprehensive nature of the inspection. While 3D scanning is more helpful in large projects (CT scanners are only used for parts and components, not entire tanks and buildings), Computed Tomography can be used to find test results for a variety of areas that would otherwise demand multiple tests to discover. 3D scanning cannot, for instance, measure the thickness of a test subject’s surface material by itself. Finding out this information would usually require a second inspection, such as an ultrasonic thickness test; CT scanning enables us to find all this information in a single CT inspection.

ATS and CT Scanning

Applied Technical Services now offers CT scanning services due to recent improvements in supporting technology. Our trained and certified technicians examine test materials with the unparalleled detail afforded by Computed Tomography and quickly produce accurate findings. ATS is one of few testing services that currently offers CT scanning, and so is breaking new ground on this method as it applies to industrial inspections. We provide businesses extended support regarding their part sample – explaining test results and sending clients off with a copy of the 3D model we generated with CT to compare against their CAD models.

The same technology empowering doctors to find miniscule tumors in a patient’s brain is now being used by our engineers to find tiny voids in casings. Allow us to give your equipment’s critical parts a clean bill of health with our comprehensive CT scanning services.
